Shokanbetsu-Teuri-Yagishiri Quasi-National Park

From Gate Park, the official schematic leads past two suspension bridges and the Hakuryu waterfall area, then up the steep Kenryuzaka section to the wetland terrace. Follow the signed one-way boardwalk before returning down the approach trail. The town gives about 11 km and 4–5 hours for this wetland circuit outing; plan 5–6 hours with rests, or more for photography. That larger allowance is editorial. Do not add the summit traverse shown on older maps.

Published walking time about 4–5 hours; editorial allowance 5–6 hours with rests.

Steep mountain trail, suspension bridges and narrow boardwalk; unsuitable for wheelchairs or strollers.

The tourism map’s island circuit links the port and settlement with Kurozaki, Akaiwa, Chidorigaura and the Kannon viewpoint before returning towards the port. It is a hilly road outing, not a continuous cliff-edge footpath. The map lists roughly 12 km around the island and a three-hour moving-time model; allow 4–6 hours with observation stops as an editorial plan. Shorten it by arranging local transport. Follow signed traffic direction and keep clear of vehicles.

Official model: about 3 hours moving; editorial sightseeing allowance 4–6 hours.

Repeated climbs and descents; accessible vehicle assistance and individual viewpoint access need checking.

The published two-hour forest route begins at the Heart Slope entrance and visits Itsukushima Shrine, Hibarigaoka Park, Onko-no-Sho and Uguisu Valley before finishing by the Aizu samurai graves. It is point-to-point, so add the walk back to your lodging or port. Look closely at the yews’ sideways growth, then pause quietly for woodland birds. The map shows wooden steps and uneven forest paths; no verified route distance is supplied.

Published route about 2 hours, plus port transfers, rests and return arrangements.

Steps and irregular woodland surfaces; not a verified step-free route.

Mashike describes two approaches: Shokan from Shokanso, with steep and roped sections, and Hashibetsu, which climbs through forest before reaching alpine flowers above the seventh station. Both need a full mountain plan and suitable experience. Choose an out-and-back from one trailhead, obtain current route information and set a turnaround time. Use a current mountain map and local advice for navigation.

A dedicated mountain day; obtain route-specific timings before departure.

Mountain terrain with steep sections; unsuitable for mobility-aid sightseeing.

In its open season, the Ofuyu viewpoint and nearby rock park offer a coastal alternative to a summit day. Treat this as a selected stop during a road journey, not a mapped walking link along the entire protected coast. Use designated access and parking; do not stop in tunnels or improvise a route below cliffs. The town lists the viewpoint for late April to mid October and closes it at night and in winter.

Allow 30–60 minutes if access is confirmed; this is an editorial allowance.

Entrance-to-viewpoint step-free access has not been verified.

Stay on Teuri if the auklet return is your priority. A guided visit helps with timing and low-disturbance viewing. The operator’s 2026 night tours ran 25 April–20 July; those dates are now past and do not establish 2027 availability. Let the guide manage lighting, and never point a bright light at birds.

On Yagishiri, children can sketch the shapes of yew branches or compare woodland sounds with the open pasture. Choose a short section and return before anyone is tired. Sheep are managed livestock: watch from the public route and keep gates and working land clear.

At Teuri’s public lookouts, try distinguishing birds resting on the water from birds flying back towards land. Binoculars make this more rewarding than approaching the colony. Keep snacks packed away and never feed wildlife. A quiet five-minute pause often suits children better than a long checklist.

Before or after the islands, the Hokkaido Seabird Center introduces Teuri’s birds through displays, a landscape model and model eggs. It is a useful bad-weather option when open, although it is outside the island park sectors. Ask children how egg shape and nesting place might be connected.

At Uryunuma in the open season, choose one small scene to study: a pool reflection, a flower beside the boards or changing cloud shadows. Photograph from the path and let others pass. Leave flowers and other plants where they grow.

A wild breeding seabird on Teuri, best associated with the seasonal evening return. View through an organized, low-disturbance outing; there is no year-round encounter promise.

Teuri’s celebrated ororon-cho has major conservation significance. Watch from authorized viewpoints and remember that decoys can be present.

One of Teuri’s documented breeding seabirds. Look from public routes, keep food away and allow nesting birds space.

Listed among Uryunuma’s wild grassland birds. Listen from the boardwalk without entering vegetation or playing calls.

These are wild woodland trees. They are shown here under the broader yew genus, Taxus; the island trees are locally called onko or ichii.

The mainland mountain and wetland country is bear habitat. This association is a safety context, not a suggestion to seek or photograph bears.

Look for Teuri’s spectacled guillemot, locally called keimafuri. In the wetland flower calendar, July brings Ezo-kanzo daylilies and hiogi-ayame irises; August includes Uryu-kohone pond lilies. These are seasonal possibilities, not promised sightings.

On Teuri, look out for spectacled guillemots from the public viewing areas. At Uryunuma in the open season, pause on the boardwalk to notice whichever wetland flowers are blooming.

The current quasi-national park was designated on 1 August 1990 by bringing together two earlier prefectural natural parks. That history helps explain why the mountain and island experiences feel so distinct.

Yagishiri’s onko are yews. Severe wind and snow help shape the low, broad branches of the island’s distinctive trees. Onko-no-Sho is a particularly memorable place to notice how a tree can spread without becoming tall.

Teuri is Japan’s only breeding site for the common murre, locally called umigarasu or ororon-cho. Conservation work has used decoys and recorded calls to attract birds back to breeding places. Do not count a stationary black-and-white figure as a living bird without checking.

Yagishiri’s woodland flowers follow snowmelt, while Teuri’s breeding season starts before mainland mountain access settles into summer conditions. An April island trip and an April wetland hike are very different propositions. Check the ferry’s vessel and timetable period.

Uryu’s FAQ points to July through mid August for wetland flowers. Mashike’s alpine flowers and lingering snow can overlap. Expect biting insects on mainland hikes, pack proper rainwear and choose your day for conditions rather than a fixed blossom promise.

Wetland flowers thin out towards autumn, giving way to tawny grasses and foliage. Teuri’s auklet spectacle has a much shorter season than the island’s general sightseeing season. Ferry frequency reduces outside summer, so a quieter visit needs more careful lodging and meal planning.

Uryunuma’s removed bridges rule out the normal visitor hike. Mountain-road closures and strong coastal weather also change access. The islands remain communities with a scheduled winter ferry, but cancellations and limited visitor services make them unsuitable for a casual summer-style day trip.

Haboro Enkai Ferry serves Yagishiri and Teuri. The 2026 October–early April timetable has one ferry circuit daily: it reaches Teuri at 10:45 and leaves at 11:35. Check the live operating notice as well as the timetable. Intercity buses reach Haboro, with a port shuttle tied to sailings; the shuttle is cancelled when boats are cancelled. Free terminal parking is listed. Reserve high-speed seats and any vehicle or bicycle carriage, and leave time for ticketing.

Uryu town’s access guidance says there is no public transport from town to Gate Park. Arrange a car or a taxi and a reliable return pickup before travelling; the road journey is about 50 minutes in normal conditions. Its narrow gravel sections need care, and large buses are not permitted. Mashike’s Shokan and Hashibetsu trailheads are different destinations, not interchangeable ends of a currently open traverse.

At the October 2026 check, general adult second-class ferry fares were JPY 1,600 one way from Haboro to Yagishiri, JPY 2,330 to Teuri and JPY 730 between islands for September–June. July–August fares are higher. These exclude vehicle carriage and high-speed supplements. The operator states cash-only payment, so carry enough cash and check prices again before travelling.

Gate Park has registration facilities, a campsite and Minami-Shokanso, but they are seasonal. There is no food sale, and local water is not potable. The shelter requires your own food and bedding and has no shower. Carry litter out; stoves and other flames are prohibited on the trail and wetland. Use toilets before starting and ask the manager about current facilities rather than assuming services continue after closure.

The municipal listing gives free admission, 09:00–17:00 from April to October and 09:00–16:00 from November to March. It closes Mondays, the day after holidays and 31 December–5 January. Check holiday exceptions and temporary notices before using it as a weather backup.

Haboro’s terminal has tactile paving, a multipurpose toilet with ostomate facilities and a nursing room. The ferry operator says wheelchair users can board with staff help. Confirm ramp conditions, onboard needs, island pickup and accommodation directly. Those facilities do not certify a step-free route to a cliff lookout or through Yagishiri’s forest.

A boardwalk can sound gentle, but Uryunuma’s boardwalk is reached only after a steep mountain approach. For limited stamina, select a short island roadside section with an agreed pickup instead. Exact gradients, path widths and accessible toilets at individual island viewpoints remain unverified.

Check local bear notices, travel in a group, keep food secured and turn back if you see a bear or fresh signs. Carry suitable bear deterrent equipment and know how to use it. Uryu advises planning to return by 16:30, descending by 17:00 at the latest and not entering before 05:00. Poor phone reception means a downloaded map, weather check and shared itinerary matter.

Stay on the public path or observation area, never step onto nesting ground, and keep children away from cliff edges. Teuri’s evening auklet guidance discourages private-car access after sunset and directs visitors to guided viewing. Follow local lighting instructions and leave when the guide ends the visit.

Strong wind or rough seas can cancel ferries and boat tours. Avoid placing a must-catch flight or other fixed commitment immediately after an island return. On walks, wet boards, exposed coast and sudden rain can make a short distance feel much longer; carry a layer you can put on quickly.
