Yakushima Hiking Guide 2026: The縄文杉 (Jomon Sugi), the Shiratani Unsuikyo Gorge and Everything You Need to Know Before You Go
Yakushima is the sub-tropical island off the southern tip of Kyushu whose ancient cedar forest — the yakusugi, trees that survive only because their timber is so dense with resin that the Edo-period loggers couldn’t be bothered to cut them — contains individuals estimated at 2,170 years old by the most conservative carbon-dating and 7,200 years old by the most generous, whose moss-covered roots and rain-soaked forest atmosphere inspired Hayao Miyazaki’s Princess Mononoke, and whose UNESCO World Heritage inscription in 1993 as one of Japan’s first two natural World Heritage Sites recognises an ecosystem that receives 10,000 millimetres of rainfall per year on the mountain peaks and produces a biological diversity equivalent to a journey from subtropical coast to subarctic summit in a single day’s hiking. Your complete 2026 guide.
Yakushima is the island that makes the word “ancient” mean something physically real rather than historically abstract — standing at the base of the Jomon Sugi, a cedar tree whose trunk circumference of 16.4 metres and whose estimated age of between 2,170 and 7,200 years (the range reflects the genuine scientific uncertainty about counting growth rings in a tree whose interior has rotted hollow, making direct core sampling impossible) places it at the outer edge of what a living organism can achieve in terms of continuous biological persistence, the traveler’s standard scale reference for “old” recalibrates permanently. The tree has been alive, in the specific forest of Yakushima’s interior, since before the Roman Republic, before the Mauryan Empire, possibly before the domestication of the horse — and it is currently alive now, photosynthesising in the rain of the island that receives more precipitation per square metre than almost any other inhabited landmass in Japan, adding another growth ring so slowly that the resin density of its wood makes it effectively immune to the fungal decay and insect damage that kills ordinary cedar in decades. Yakushima is a roughly circular island 132 kilometres in circumference and 503 square kilometres in area, 60 kilometres south of Kagoshima at the southern tip of Kyushu, whose central mountain peaks reach 1,936 metres (Miyanoura-dake, the highest peak in Kyushu) and whose altitude range from sea level to that summit produces the ecological equivalent of a journey from the subtropical south of Japan to the subarctic north in the 20-kilometre horizontal distance between the beach and the ridge. The island receives 4,000 to 10,000 millimetres of rainfall per year depending on elevation — the coastal villages get the 4,000mm that makes Yakushima Japan’s wettest major inhabited island, the mountain peaks get the 10,000mm that produces the rainforest conditions whose permanent moisture the 1,000-year-old moss carpet on every rock and root in the old-growth forest derives its specific visual quality from. The Miyazaki connection is not marketing mythology — Hayao Miyazaki visited Yakushima’s Shiratani Unsuikyo gorge in the research phase for Princess Mononoke (1997) and the film’s forest deity kodama-inhabited forest is a direct visual transcription of what Shiratani Unsuikyo looks like in the rain: moss-covered boulders, multi-trunked yakusugi rising from root platforms above the accumulated forest floor, pale green light filtering through a canopy so dense that the ground beneath it never fully dries between rainfalls, and the specific silence of a forest whose only sound is the rain on the leaves and the Miyanoura River’s white water in the gorge below.
Understanding Yakushima’s Natural World
Yakushima’s ecological significance rests on the vertical biodiversity compression that the island’s 1,936-metre altitude range produces — the transition from the coastal subtropical forest (banyan, camellia, and warm-temperate broadleaf species at sea level) through the temperate broadleaf zone (oak, laurel, and the lower yakusugi at 500 to 1,000 metres) to the old-growth yakusugi cedar zone (the yakusugi in its true habitat, 1,000 to 1,800 metres, the elevation band where the rainfall, the temperature, and the soil chemistry combine to produce the extreme resin density that makes the trees effectively immortal) to the alpine grassland and dwarf bamboo heath at the summit ridges above 1,800 metres. This vertical journey through what botanists describe as the equivalent of the complete vegetation sequence from Kyushu to Hokkaido — roughly 2,000 kilometres of latitudinal distance compressed into 20 kilometres of vertical altitude gain — is the scientific basis for the UNESCO World Heritage inscription and the experiential basis for the hiker’s sensation of having traversed a continent in a single day. The Yakushima macaque and the Yakushima sika deer are the island’s two endemic subspecies — both present in such high density that they constitute a routine encounter on every trail, the macaques foraging along the Jomon Sugi approach trail with complete indifference to the passing hikers, and the deer whose population the island’s road network has produced the specific evolutionary pressure of vehicle-avoidance on in a single generation. The forest’s biological relationship between the macaque, the deer, and the yakusugi is one of the most studied plant-animal interactions in Japanese ecology — the macaques eat the cedar seeds, the deer eat the fallen cedar bark, and the yakusugi’s fallen branches provide the nurse log substrate on which the next generation of cedar sprouts in the specific regeneration cycle whose slow pace matches the tree’s slow growth and extreme longevity.
The Yakusugi: What Makes These Trees Extraordinary
The designation “yakusugi” applies specifically to the Japanese cedar (Cryptomeria japonica) trees on Yakushima that are more than 1,000 years old — trees below that age are called “kosugi” (small cedar) regardless of their size, a classification whose arbitrary-sounding threshold reflects the genuine biological threshold at which the resin concentration in the wood reaches the density that makes the tree effectively resistant to fungal decay. The yakusugi’s extraordinary longevity is not the result of a particularly favourable growing environment — quite the opposite. The island’s granite geology produces a thin, nutrient-poor soil whose mineral scarcity forces the cedar to grow extremely slowly, adding approximately 1 millimetre of ring width per year compared to 3 to 5 millimetres for the same species on the Japanese mainland. The slow growth concentrates the resin in each annual ring to a density that the faster-growing mainland cedar never achieves, producing a wood so saturated with antimicrobial and anti-fungal chemical compounds that the fungal decay that kills most trees within 500 years cannot penetrate the heartwood in the same timescale — the yakusugi simply outlives everything that would normally kill it by being too dense and too chemical-rich to rot. The Edo-period logging of Yakushima (1640s to 1800s) removed the accessible, lower-elevation cedars but left the high-altitude yakusugi because the extreme terrain cost of transporting the timber down to the coast exceeded the timber value — the logging infrastructure built for the lower-elevation harvest is the network of ancient sled tracks (momoke-do) that the modern hiking trails follow up to the yakusugi zone, whose impracticality for the loggers has become the accessibility that the hikers use 400 years later.
The Jomon Sugi Trail: Complete Guide
The Jomon Sugi trail is the defining Yakushima hike — a 22-kilometre round trip (10 kilometres each way from the Arakawa Trail Head to the tree) that gains 600 metres in elevation and takes between 8 and 10 hours for the average hiking group, passing through the complete vegetation sequence from the lower broadleaf forest to the old-growth yakusugi zone in the most well-maintained and most heavily used single-day hike in Kyushu. The trailhead is at Arakawa-tozan-guchi — accessible by shuttle bus from the Yakusugi Land bus stop in the permit season (March 1 to November 30), when private vehicles are prohibited on the Arakawa Forest Road beyond the Yakusugi Land parking area. The shuttle bus departs from approximately 5:00 AM and runs every 15 minutes through the morning — the first shuttle is the correct departure for the Jomon Sugi day trip, as the 8 to 10-hour round trip requires the earliest possible start to complete before the last return shuttle at approximately 5:00 PM. The trail for the first 8 kilometres follows the abandoned Anbo-gawa Forest Railway — a flat, wide track laid on the former narrow-gauge railway bed that the Taisho-era logging operation built to transport timber from the interior, whose flat grade and wide surface make the initial approach a fast and easy walk before the steeper section above the Wilson Stump junction. Wilson Stump is the first major stop — a hollowed yakusugi stump 13 metres in diameter whose interior is large enough to stand inside (the stump’s hollow core has been used as a shelter, a shrine, and most recently as the most photographed interior space on Yakushima for the heart-shaped sky visible through the opening from the correct crouching position). The stump is the remainder of a tree felled in the Edo-period logging under the order of the daimyo Toyotomi Hideyoshi — the felling was carried out by the botanist Wilson (after whom the stump is named) on his early 20th-century survey, and the stump’s circumference of 13 metres suggests an original tree of approximately 3,000 years. The final section from the Wilson Stump junction to the Jomon Sugi viewing platform is the steepest and most demanding of the trail — the boardwalk approach to the tree’s observation deck gains 300 metres in 3 kilometres on a surface that the rainfall makes slippery throughout the year and especially in the July-August typhoon approach season. The Jomon Sugi itself is viewed from a wooden observation deck 20 metres from the trunk — the barrier was installed after the tree’s bark showed damage from visitor touching, and the 20-metre viewing distance is a conservation compromise whose slight visual frustration the specific quality of being in the physical presence of a 2,000-plus-year-old organism significantly outweighs.
Trail Logistics and Permit Requirements
The Jomon Sugi trail requires registration at the Arakawa Trail Head registration station — a trail count system rather than a permit quota, but the information registered (name, hiking party size, planned route) is used for emergency rescue coordination and is legally required for access to the World Heritage Zone trails. There is no trail fee for the Jomon Sugi route itself, but the Yakushima World Heritage Conservation Centre collects a voluntary environmental contribution of 1,000 yen per person at the trailhead. The shuttle bus from Yakusugi Land to Arakawa-tozan-guchi costs approximately 440 yen each way (2026 rate — confirm at the Anbo Forest Management Office website). Essential gear: waterproof jacket and trousers (the island’s 10,000mm annual mountain rainfall means the probability of rain during any Jomon Sugi day hike is approximately 100% across the full year), hiking boots with ankle support and aggressive tread (the trail’s wet roots and boardwalk sections require grip rather than trail runner rubber), hiking poles (the descent’s steep boardwalk sections are significantly safer with poles), and a headlamp for the early departure and any extended return. Carry 2 litres of water minimum and lunch — there are no facilities between the Arakawa Trailhead and the Jomon Sugi observation deck.
Shiratani Unsuikyo: The Princess Mononoke Forest
Shiratani Unsuikyo is the ravine and forest park 12 kilometres from Miyanoura that the Princess Mononoke art direction team used as the reference landscape for the forest deity sequences — a 426-hectare protected area of old-growth broadleaf and yakusugi forest whose combination of the Shiratani River’s clear water rapids, the moss-covered boulders and root networks of the ancient cedar zone, and the specific quality of the diffused green light in the old-growth canopy produces the precise visual environment that the film’s forest scenes replicate in animation. The park is accessible without a guide and without a shuttle bus restriction — a car or taxi from Miyanoura reaches the park entrance in 30 minutes, and the trail system offers options from the 1-hour easy circuit of the lower gorge to the full-day traverse to the Yakusugi Land junction via the Taikoiwa rock summit viewpoint. The Taikoiwa rock viewpoint is the specific reason to do the full Shiratani Unsuikyo day circuit rather than the lower gorge loop — a massive granite boulder at 920 metres elevation whose summit provides the panoramic view of the island’s forest canopy, the southern Osumi strait, and on clear days the outline of Kuchinoerabu Island to the south-west in the specific visual reward that the 3-hour uphill through the old-growth cedar forest earns. The park entrance fee is 500 yen (2026 rate — confirm at the Yakushima Environment and Culture Foundation website). The trail is open year-round without shuttle bus restrictions, making Shiratani Unsuikyo the accessible alternative for days when the Jomon Sugi shuttle is full or the weather makes the high-elevation Jomon Sugi trail unsafe.
Miyanoura-dake Summit Trek
The Miyanoura-dake summit (1,936 metres) is the highest point in Kyushu and the most physically demanding single day-hike on Yakushima — a 23-kilometre traverse from the Arakawa Trail Head to the Shiratani Unsuikyo entrance via the summit ridge whose 11-hour completion time and 1,600-metre elevation gain place it firmly in the advanced hiking category requiring full alpine day-hike preparation. The route ascends the Arakawa Forest Railway track to the Wilson Stump junction, then diverges north up the increasingly exposed ridgeline to the summit via the Hanano-ego (flower flatland) alpine meadow at 1,550 metres — a plateau of yakushima rhododendron and mountain azalea whose spring bloom from late April to early June produces the most spectacularly coloured high-altitude landscape on the island, the pink and white flower carpet at 1,500 metres with the summit visible above and the forest canopy visible below. The summit in clear conditions provides the view across the East China Sea whose enclosing cloud cover gives Yakushima its perpetual precipitation — the horizon-to-horizon water view from the Kyushu region’s highest point on a rare clear day is the specific reward whose rarity makes it the Yakushima summit experience that the repeat visitor returns for. Weather on the summit ridge changes with the specific rapidity of an ocean island — a clear departure from the trailhead can become a zero-visibility cloud envelopment at the summit plateau in 2 hours, and the summit is not a place to wait out deteriorating weather.
Yakushima’s Other Trails and Natural Sites
Kigensugi and the Northern Circuit — The Kigensugi cedar (estimated 3,000 years old, 8.1 metre trunk circumference) in the island’s northern interior is the most accessible single old-growth yakusugi tree for the visitor who cannot commit to the full 8 to 10-hour Jomon Sugi day — a 2-kilometre return trail from the Kigensugi Forest Road accessible by car, taking approximately 1 hour return. The trail passes the Futago-sugi (Twin Cedars, two trees whose trunks have fused in a single growth) and the Bugyosugi (Magistrate Cedar, another Edo-period survivor) before reaching the Kigensugi clearing whose tree — while smaller than the Jomon Sugi — is accessible without the shuttle bus restriction and without the trail registration requirement that the World Heritage Zone trails impose.
Oko-no-taki Waterfall is the largest waterfall on Yakushima — a 88-metre single-drop fall on the Isso River whose combination of the jungle vegetation on the surrounding cliff face and the spray cloud at the base produces the most spectacularly photogenic single natural feature on the island in the rainy season. Accessible by a 15-minute walk from the road at the western coast — the correct afternoon stop for the circumferential road circuit that connects the island’s coastal settlements.
Nagata Beach Sea Turtle Watching — Nagata Inakahama Beach on the island’s north-west coast is the most important loggerhead sea turtle nesting beach in the East Asian Pacific — the beach where approximately 600 female loggerheads come ashore between May and July each year to nest, producing 10,000 to 20,000 eggs per season in the largest single loggerhead rookery in Japan. The watching programme (Inakahama Sea Turtle Watching, operated under strict protocols by the Yakushima Umigame-Kan conservation centre) provides guided beach access from June to July, the season when both the nesting adults (arriving at night) and the hatchlings (emerging at dawn in August) are simultaneously present on the beach. The watching programme requires advance reservation and the guide supervision that the conservation protocol mandates — no torches, no flash photography, and the specific approach distances that the nesting turtle’s sensitivity to light and disturbance requires. The loggerhead emergence from the water at night — a 130-kilogram, 80-centimetre reptile crossing the beach under the starfield in the complete darkness of the torch-prohibition protocol — is the most directly affecting wildlife encounter on Yakushima and one of the most affecting on the entire Pacific coast of Japan.
Where to Stay
Yakushima’s accommodation is concentrated in three coastal settlements — Miyanoura on the north coast (the ferry terminal and the island’s main commercial centre), Anbo on the east coast (the closest settlement to the Arakawa Jomon Sugi trailhead junction), and Yakushima-cho on the south coast (warmer, less rain, the sea turtle beach access). The correct base for the Jomon Sugi hike is Anbo — 20 minutes’ drive from the Yakusugi Land parking area, the closest settlement to the Arakawa approach. The correct base for the Shiratani Unsuikyo circuit and the island exploration is Miyanoura — the most accommodation-complete settlement, the ferry terminal access, and the 30-minute road connection to Shiratani Unsuikyo. Yakushima Iwasaki Hotel is the island’s most established resort accommodation, on the coast south of Miyanoura at approximately ¥20,000 to ¥45,000 ($133 to $300 USD) per person including dinner and breakfast — the Japanese ryokan-style dinner and the onsen (hot spring bath) providing the precise physical recovery tool that a 10-hour wet-forest hike specifically requires. The Yakushima Sanso and Yakushima Youth Hostel near Miyanoura provide budget accommodation at ¥3,500 to ¥6,500 ($23 to $43 USD) per person — the youth hostel’s hiking community atmosphere, the trail condition information board at the reception, and the shared kitchen and common room where the evening’s trail stories circulate constitute the social infrastructure of the Yakushima hiking community that the resort hotel’s individual room format does not replicate. Mountain huts on the high-altitude routes — the Yodogawa Mountain Hut, the Ishizuka Mountain Hut, and the Shintakatsuka Mountain Hut — provide the basic but genuine shelter for multi-day traverse hikers at free or nominal cost on a first-come basis, sleeping bag required.
Best Time to Visit
Yakushima’s rainfall is its constant and defining condition — the island receives rain on approximately 320 days per year at the mountain interior and approximately 250 days per year at the coast, making the conventional “avoid the rain” travel season planning inapplicable. The rain is not the obstacle to the Yakushima visit — the rain is the Yakushima visit’s specific quality, the moisture that produces the moss carpet, the river volume, the waterfall flow, and the specific diffused green light in the forest canopy that dry-weather visiting would remove along with the inconvenience. The specific seasonal variations: spring from March to May brings the rhododendron and azalea bloom on the high ridges (late April to early June for the Hanano-ego alpine meadow), moderate rainfall, and the warming temperatures that make the full traverse comfortable without the heat management that August requires. The rainy season proper from June through August brings the heaviest rainfall, the most dramatic waterfalls, the sea turtle nesting programme, and the typhoon approach season from August that produces the specific risk of trail closure and ferry cancellation that the August visitor must plan for with flexible travel dates. Autumn from September to November is the most balanced season — reduced typhoon risk after mid-September, autumn colour on the lower broadleaf zone from late October, and the trail conditions at their most stable for the Jomon Sugi and Miyanoura-dake circuits. Winter from December to February is cold at elevation (snow on the Miyanoura-dake summit from December), very few visitors, and the low-elevation coastal forest at its quietest — the Shiratani Unsuikyo in the winter rain is the most atmospherically intense version of the Princess Mononoke forest available, the cold air and the bare-branched deciduous layers above the yakusugi reducing the visual filtering and revealing the forest structure in its most directly architectural form.
Getting to Yakushima
Kagoshima is the gateway to Yakushima — the high-speed Jetfoil ferry from Kagoshima Honko ferry terminal covers the 60 kilometres to Miyanoura in 1 hour 50 minutes (Toppy and Rocket services operated by Cosmo Line and Iwasaki, approximately ¥9,200 each way in 2026 — confirm the current fare and schedule at cosmolinejet.jp). The slower car ferry takes 4 hours and carries vehicles at approximately ¥4,000 per passenger. Kagoshima Airport receives domestic flights from Tokyo Haneda and Osaka Itami — ANA and JAL serve the route with approximately 2-hour flight times and fares from ¥15,000 to ¥40,000 ($100 to $267 USD) depending on advance booking timing. Yakushima Airport (IATA: KUM) on the island’s north coast receives 6 to 8 direct flights daily from Kagoshima Airport on JAL subsidiary Japan Air Commuter (30-minute flight, approximately ¥12,000 to ¥22,000 one way) — the fastest connection from Kagoshima to the island at the cost of the specific transition quality of the ferry approach whose gradual oceanic approach to the island’s forested silhouette the airport connection eliminates.
Trip Planner: Real Costs 2026
Getting There: Tokyo to Kagoshima domestic flight approximately ¥15,000 to ¥35,000 ($100 to $233 USD). Kagoshima to Yakushima Jetfoil approximately ¥9,200 ($61 USD) each way. Delhi to Tokyo return approximately $550 to $900 USD (ANA direct or via Singapore, Kuala Lumpur, or Bangkok).
On-Island Transport: Yakushima has no train — the circumferential road is served by bus (¥180 to ¥1,000 per journey, ¥1,230 for the day pass) and by hire car (approximately ¥6,000 to ¥10,000 per day for a compact car, ¥8,000 to ¥15,000 for a 4WD). The hire car is the correct choice for access to the Kigensugi, the Oko-no-taki Waterfall, and the coastal circuit — the bus covers the main settlements but not the forest road access points. The Arakawa Jomon Sugi shuttle bus is ¥440 each way.

FAQ
Do I need a guide for the Jomon Sugi trail?
A licensed guide is not legally mandatory for the Jomon Sugi trail — the route is well-marked with wooden signboards in Japanese and English throughout, and the flat forest railway approach for the first 8 kilometres cannot be missed regardless of navigation ability. The guide is recommended for first-time visitors for the specific trail knowledge (current conditions of the boardwalk sections, the weather window prediction from the morning sky reading that experienced Yakushima guides perform with remarkable accuracy, and the botanical identification and yakusugi ecology explanation that transforms the trail from a physical challenge into an educational experience) and for the group safety function on the steeper post-Wilson-Stump section in deteriorating conditions. Licensed guide hire approximately ¥30,000 to ¥55,000 ($200 to $367 USD) per group of up to 5 people for the full Jomon Sugi day — the per-person cost shared across a group of 4 is ¥7,500 to ¥13,750 ($50 to $92 USD), which in the context of the trail’s physical demands and the specific forest interpretation value is the most efficiently spent single planning cost in the Yakushima itinerary.
How rainy is Yakushima really and what rain gear do I actually need?
Yakushima receives an average of 4,000mm of rainfall per year at the coast and 10,000mm at the mountain peaks — roughly 4 to 10 times the annual rainfall of Delhi’s monsoon season, distributed across the full year without the dry-season respite that makes the Delhi comparison somewhat misleading in terms of the specific quality of perpetual moisture the island produces. The practical implication for the trail hiker: assume it will rain on every mountain trail day regardless of the morning forecast, because the specific atmospheric dynamics of an ocean island with 1,900-metre peaks generate local orographic rainfall independent of the broader weather system. The gear requirement is fully waterproof jacket and trousers (not water-resistant — genuinely waterproof with sealed seams, Gore-Tex or equivalent), waterproof gaiters for the root and boardwalk sections, and hiking boots that are either fully waterproof or so thoroughly soaked within the first 30 minutes that the hiker accepts the wet-boot reality and focuses on grip rather than dryness. The traveler who arrives on Yakushima with a rain jacket rated “shower resistant” and trail runners with mesh uppers will be cold, wet, and unhappy within 2 hours on the Jomon Sugi trail. The traveler who arrives with the correct rain system will be wet on the outside, dry on the inside, and entirely comfortable in the specific quality of hiking through an ancient rainforest whose visual and sensory dimensions are enhanced rather than diminished by the rain that created them.
Can I combine Yakushima with other southern Japan destinations?
The most natural combination is the Kagoshima-Yakushima-Amami Oshima island circuit of the Kyushu south and the Ryukyu chain — Kagoshima as the gateway with the Sakurajima volcano day trip, Yakushima for 3 to 4 nights for the full hiking circuit, and then the ferry south to Amami Oshima or the Ryukyu archipelago’s northernmost inhabited islands for the coral reef and subtropical beach extension of the same southern Japan nature circuit. The direct ferry service from Yakushima south to Amami Oshima and the Tokara Island chain connects the Yakushima visit to the Ryukyu archipelago without returning to the mainland — a logical southward progression for the traveler whose Japan itinerary is running south toward the Okinawa destination that the Ryukyu circuit’s cultural and marine distinction makes the natural completion. The Tokyo-Osaka-Kyoto-Kagoshima-Yakushima sequence on the Shinkansen south from the main cultural cities and the Yakushima ferry connection produces the most complete single Japan circuit available in 10 to 14 days, combining the Buddhist temple and modern urban Japan of the central cities with the rainforest, volcano, and ocean island Japan of the south whose tourist circuit the Shinkansen has made more accessible than the island geography implies.
Is Yakushima accessible for older or less experienced hikers?
Yakushima provides a full spectrum from completely accessible to highly challenging — the Kigensugi trail (2km return, 1 hour, flat forest path) and the lower Shiratani Unsuikyo gorge circuit (2 to 3 hours, modest elevation gain, well-maintained boardwalk) are accessible for any moderately fit adult without specific hiking experience. The full Jomon Sugi trail (22km, 8 to 10 hours, 600m elevation gain) requires good fitness and prior hiking experience with long trail days — the physical demand is not extreme by alpine standards but is sustained, and the wet surface of the root and boardwalk sections requires the confidence and the grip footwear that first-time hikers on wet trails sometimes underestimate. The Miyanoura-dake summit traverse (23km, 11 hours, 1,600m elevation gain) is an advanced mountain day hike requiring full alpine preparation and prior experience with multi-hour high-altitude trails in variable weather. The correct Yakushima itinerary for the experienced but not specialist hiker is Shiratani Unsuikyo full circuit on Day 1 for the warm-up, Jomon Sugi on Day 2 for the main event, and Kigensugi and coastal circuit on Day 3 for the recovery day — a 3-day programme that covers the island’s most significant natural content within the physical range of the fit recreational hiker without the mountaineering experience that the Miyanoura summit traverse additionally requires.
