Illustration of Shomyo Falls, จังหวัดโทยามะ — ภาพประกอบ (ไม่ใช่ภาพถ่าย)

Shomyo is the tallest waterfall in Japan: 350 metres in four stages down a wall of columnar rock at the western edge of the Tateyama massif. At full flow it moves more than a hundred tonnes of water a second, and the noise reaches you well before the falls come into view. It is designated both a national Place of Scenic Beauty and a Natural Monument.

In spring, and after heavy rain, a second fall appears alongside it. Hannoki is seasonal and therefore not counted in the official rankings, but at around 500 metres it is taller than Shomyo — for a few weeks each year Japan's highest waterfall is standing right next to its highest waterfall and nobody lists it. Access is by a road that closes in winter and in bad weather, from a car park half an hour's walk below the viewing point. It is the only part of the Tateyama area you can reach without buying an Alpine Route ticket.

การเดินทางไป

ข้อมูลการเดินทาง

Ashikuraji, Tateyama, Nakaniikawa District. From Tateyama Station take the Shomyo Falls sightseeing bus, about 15 minutes, or drive from Tateyama IC to the Shomyodaira car park; from there it is Near the falls. Free to visit. The access road generally operates 7:00 AM – 6:00 PM in April to June and September to November, with adjusted hours in peak summer, and closes in winter. It also closes in bad weather — thresholds are around 70 mm of cumulative rain, 30 mm an hour, or 30 m/s winds.

คู่มือจากคนใน

**Late spring for two waterfalls.** Snowmelt in late April through June brings Hannoki Falls out beside Shomyo at around 500 metres. It is the single best reason to time a visit, and it disappears when the melt ends. **Thirty minutes uphill from the car park.** The walk is on a paved road with a steady gradient. It is not difficult but it is not a viewpoint you drive to, and you do it twice. **The road closes on rain thresholds, not on judgement.** Cumulative rainfall of about 70 mm or 30 mm in an hour shuts the access road. Check the Tateyama town notice before setting out in unsettled weather. **It is outside the Alpine Route ticket.** Everything else at this altitude in Tateyama requires an expensive multi-vehicle pass. Shomyo does not, which makes it the cheapest way to see the scale of this mountain wall. **Winter closes it entirely.** The road shuts under snow from roughly December to April. There is no winter access.
