“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.
No accommodation listed on Rakuten Travel was found within 3 km of this road. The search was therefore widened to 10 km, nearest first. Distances are straight-line distances from the road, not road distances — 5 km with a mountain in between can still take an hour to ride. We do not know whether these places are open or have rooms free — availability and prices are not checked. Only places listed on Rakuten Travel appear here, so this is not everything within range, and only places in the same prefecture are searched: somewhere just across a prefectural border may well be closer.
| Name | Operator | Straight-line distance | Map |

| 下久保ダム | － | 4.5km | GSI Maps / Google Maps |
| 合角ダム | － | 4.8km | GSI Maps / Google Maps |
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.
