Kamisuwa Onsen
One of Japan’s premier hot springs towns, Kamisuwa Onsen gets much of its water from the springs underneath Lake Suwa. The water is of high quality and the main onsen are in the areas directly surrounding the lake. Footbaths, a regular feature in the region, are often complemented with smooth stones on the floor of the bath, which are superbly therapeutic for your feet.
Shimosuwa Onsen
There are a variety of hot springs in this area, which is known for water with an extraordinarily high sulfur and salt content and, historically, as a healing spot for wounded samurai. For those looking to test their mettle, try the extremely hot baths at Tanga no Yu that reach up to 52°C (125°F). Baths of standard temperature are available next to the ultra hot baths. There are also many traditional bathhouses in the area that appeal to locals.
Tateshina Onsen
Tateshina has been considered a health resort area for a long time. The water can vary greatly in temperature and be quite beneficial to healing. Hot springs in the area are often a part of Japanese inns, but there are a few public bathhouses as well. Many of the baths are built outdoors in the traditional style, with views of the surrounds. The area is especially famous for its stunning mountain views. Tateshina is known as a stopping point for the famous daimyo (feudal lord) Takeda Shingen (1521-73) during his visits through Suwa.
Incredibly Hot Onsen
A few of the bathhouses in the Suwa area are outfitted with extremely hot pools. Legend says the hot waters of the area were perfect for healing wounded samurai. Try the extremely high temperature baths at Tanga no Yu that reach up to 52°C (125°F). For the most part, people dare to submerge or partially submerge themselves for mere seconds. Baths of normal temperature are also available.
