As temperatures around the country fall, now is the perfect time to indulge in the Japanese pastime of onsen. Best described as a hot spring bathing spa, onsen is a long held tradition in Japan and the near endless supply of geothermal springs is the one positive aspect of living in a nation of constantly shifting tectonic plates. Below are some of the most highly regarded onsen areas in the country.
Kurokawa Onsen, Kyushu
The island of Kyushu is known for being perhaps the best area for onsen, and Kurokawa Onsen is probably the pick of the bunch. Located around 20 kilometres (12 miles) from Mount Aso, it is a beautiful town that has retained its traditional charm and resisted the big money lure of the concrete and neon spa hotels you find elsewhere. Kurokawa Onsen is particularly well known for its ‘rotenburo’ (outside baths) next to rushing rivers, such as the Yamamizuki bath, considered one of the best riverside baths in Japan .
Beppu Onsen, Oita
Another Kyushu based onsen area, Beppu, in Oita prefecture, is one of the country’s best known, and produces eight different springs. One of the most remarkable things about the onsen in Beppu, aside from the fact that you can see the steam rising up all over the city, is the variety of bath types. Rather than just having hot water onsen, Beppu also boasts steam baths, hot mud baths and sand baths where bathers are buried in naturally heated sand. If you want to try out the latter, head to Takegawara Spa. It was constructed in 1879 and is perhaps Beppu’s most famous bathhouse. Though be warned, the building is partially surrounded by a red light district.
Kusatsu Onsen, Gunma
Located in the mountains of Gunma at 1200 metres (4,000 ft) above sea level, Kusatsu Onsen is probably Japan’s most popular spa, and has been listed in Japan’s Top 100 Onsen at number one for the last 12 years in a row. The high quality water, as much as 32,300 liters of it being discharged every year making it the greatest quantity in Japan, is said to cure all diseases bar love sickness. The unique bathing method of jikanyu (where bathers sit in 48 degree water for exactly three minutes) and yumomi (stirring the water with long planks for cooling the temperature of the water, also serving as an important pre-bathing exercise) are customs that have been passed down since the Edo period.
Hakone Onsen, Hakone
If you want an onsen with a view, you can do no worse than gazing out over Mount Fuji as you soak in your spa. It is perhaps more down to its stunning view and its close proximity to Tokyo that makes the spa town of Hakone so popular, but what a view it is! Of course not all spas in the area have the advantage of being in eyeshot of the nation’s most enduring symbol, but if you can find one – particularly during the time of the magical Diamond Fuji – there is possibly a no greater Japanese experience.
Noboribetsu Onsen, Hokkaido
Noboribetsu is considered to be the best onsen in the northern island of Hokkaido. Part of the Shikotsu-Toya National Park, there are nine different kinds of water including various minerals such as iron, salt and sulphur. The latter is considered to be particularly good for the skin, but doesn’t leave you smelling so fresh (as a suggestion: don’t plan a long train journey directly after a sulphur bath. Your fellow passengers will not appreciate it).
Okuhida Onsen, Gifu
This one comes with a personal recommendation. Set up in Gifu Prefecture’s Northern Japanese Alps, the spa valley of Okuhida is a beautiful little spot famed for its outdoor rotenburo baths. There are a variety of bathing types, both segregated and mixed (some prefectures do not allow mixed bathing, though Gifu is not one of them), with five water sources feeding the towns along the valley. The largest, and oldest, is Hirayu Onsen, and is said to have been discovered in the 1560s by Takeda Shingen’s troops as they crossed through the Okuhida region.
