“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.

Whether you can ride it is not stated here
