Yunokawa Onsen

Yunokawa Onsen (湯の川温泉), over 300 years old, is a nest of relatively built up hotels and spa complexes and has little of the character one might hope for in a venerable old onsen. Yet it's easily accessible from Hakodate by the tram, which makes higaeri (day trips) a breeze.

Jouzankei Onsen

Jouzankei Onsen is one of the nearest major onsen towns close to Sapporo, and those seeking a quick soak without a lot of atmosphere will enjoy the warmth of the various hotel baths.

Namari Onsen

Namari Onsen is in the labyrinthine complex of the Fujisan Ryokan (藤三旅館‎), the highlight of which is the White Monkey Bath (白猿の湯), a 1.4 meter deep, wonderfully hot oval of konyoku perfection with a rough, natural bottom and tiled sides. A small lip at the edge lets one ease in. Though konyoku (mixed gender) the White Monkey Bath has Ladies only hours, so pay attention to the signs outside the entry doors.

Asama Onsen

Just minutes walk from Asama Station, Asama Onsen's "Biwa no Yu" boasts a beautiful and relaxing rotenburo, as well as separate male/female baths.

Aoni Onsen

One of the most beautiful onsen in Japan, Aoni is famous for its great baths and atmospheric, fragrant oil lamps, which are lit nightly.

Houheikyou Onsen

Close to Sapporo and boasting 100% real onsen water, this restaurant/onsen establishment features dark brown water, several uchiburo, and a large rotenburo with views of the surrounding hills.

Zaou Onsen

This ski town offers old-style donation-entry baths, plus giant 200 person rotenburo for anyone who's looking for a crowd.

Shirahama Onsen

Seven public baths to hit along the inlet shore, all within about 20 minutes' walk from each other, with Saki-no-yu (崎の湯) at the top: right by the ocean's shore.
