Japan Onsen are the place to unwind. We focus on local mountain onsen (hot springs) in Niigata and Nagano such as Myoko Onsen, Akakura Onsen, Suginosawa Onsen, Ikenotaira Onsen, Tsubame Onsen, Seki Onsen, Madarao, Iiyama and many more. Jigoku-dani valley between Mt. Myoko and Mt. Mae is the rich source of the local onsen hot springs.

Opened in 1816, Akakura Onsen is the largest of Myoko's onsen, and one long popular with Japanese and international tourists. The Akakura Hot Spring is located at the foot of the 800-meter tall Mt. Myoko in Niigata Prefecture and draws its sulfate water from this mountain - one of the hundred famous mountains of Japan with a height of 2454 meters. The spring has two types of water quality and has a good reputation for making the skin beautiful while also curing wounds. The water is renown for its rejuvenating properties, so some Japanese names for it translate as “water for beautiful women” and “natural skin toner”. Taki no Yu (pictured at right) gets about 3000 litres per minute of gensen kakinagashi (pure onsen in and out). It is closed in winter |

Set on a spectacular cliff-side setting, Tsubame Onsen has long been a destination for those desiring the road less traveled. The spring boasts white yubana (flower shaped crystals) in its mineral rich waters. The atmosphere here is somewhat nostalgic - reflecting a Japan of the post-war era. Some Tsubame Onsen hotels and facilities close here in the wintertime due to the famous heavy snows but others offer a unique wintertime experience - some only with access by snow cat. Ougon no Yu (pictured above), which has pools separated by bamboo mats, is one of the two free onsen that can be reached by hiking out on one of the trails leading up to Mt. Myoko from the top of the village area. Take the path to the left for about 3 minutes up a steep hill (the old ski area). The other, Kawara no Yu, is a konyoku rotemburo onsen (mixed gender outdoor bath). For this one you have to take the right track for about ten minutes, cross over a suspension bridge, then take the small river path to the left for about 5 minutes. Pack your own towels (and modesty). |
