Cloudy white sulphur water at 500 yen, in a wooden bathhouse standing in the woods below the Unzen village. The spring is a simple sulphur spring of the hydrogen-sulphide type - weakly acidic and hot at the source - and it smells like it. The trade-off is the setting: it is off the village strip, so you get trees and quiet but you are a walk or a short drive from anything else, and the bathhouse charges for amenities.

Every onsen on this site is scored against the same written rubric, and every score has been reviewed by the editor. The ones marked Visited were also bathed in personally.

Why Agoda for Japan: it lists a lot of ryokan and small inns that the Western booking sites never picked up, and it usually prices Japanese properties in yen, so you are not paying a conversion spread on top of the room rate. Worth comparing before you book — the difference on a ryokan is often larger than you would expect.

About the day-pass link: Asoview is the main place day-use onsen in Japan sell entry tickets and discount coupons in advance. It is a Japanese-only site, so use your browser’s translation — you show the ticket on your phone at the door.
