“Rakuten Travel” buttons are affiliate advertising: bookings made through them earn this site a commission. Which places appear, and in what order, is decided by distance alone. A missing button only means we could not find the place on Rakuten Travel — it does not mean it is closed.
Only places found in OpenStreetMap or on Rakuten Travel
appear here. There are very likely more nearby — this table is not a complete list.
Names and locations are collected mechanically from those two sources (huts and campsites
from OpenStreetMap, bookable inns from Rakuten Travel).
The distance is a straight line from the road, not a route you can ride
(500 m across a valley may be unreachable). We do not know whether a place is open,
takes guests, or lets you bathe — neither availability nor rates were checked.
Emergency huts and university lodges are excluded. "onsen" appears only where
bath:type=onsen is mapped; its absence does not mean the water is not hot-spring water.

These dams are mapped in OpenStreetMap. The distance is a straight line from the road, not a route you can ride. We do not know whether you can get close — many dams sit behind maintenance roads that are closed to the public. Check dams (sabo dams) and weirs are excluded: they are flood-control structures and some are dangerous to approach. OpenStreetMap does not record whether a dam is a check dam, so to avoid listing one by mistake we keep only dams with a known operator, an encyclopaedia entry, or an official website. Some real dams are missed as a result.
