The charm of Shima Onsen with its nostalgic atmosphere

Gunma Prefecture is a hot spring country with many hot spring areas such as Kusatsu Onsen and Ikaho Onsen. Among these, Shima Onsen, which is located in Joshinetsu Kogen National Park and spreads along the clear Shima River, is attractive for its Showa-era retro townscape and the high quality of its spring water, which is not often seen as a tourist destination.

The quality of the spring water is said to be ``a spiritual spring that heals 40,000 illnesses.''

Due to its excellent spring quality, Shima Onsen has been designated as a national recreational hot spring area . The quality of the spring water is ``sodium/calcium-chloride/sulfate spring (weak saline spring)'', and you will feel a slight salty taste when you drink it. It is said to be effective for gastrointestinal diseases, neuralgia, and rheumatism, and is also known as a hot spring that does not easily cool you down due to the heat-retaining effect of the salt.

Shima Onsen is also characterized by the fact that most of its sources are natural. Although there are various theories, one theory is that Sakanoue Tamuramaro, a general of the Conquerors during the era of Emperor Kanmu (737-806), took a bath in this area, which indicates that there was an abundance of hot springs gushing out from ancient times. . From here, we will introduce recommended spots you should visit at Shima Onsen.

A communal hot spring located in the Hinatami district, a little further inside Shima Onsen. It is also a place where there is a legend that a long time ago, a mountain god who had a dream come true and said, ``I will give you a spiritual spring that will heal 40,000 illnesses,'' and when you woke up, the hot spring was gushing out from under your pillow.

The wooden and bathhouse-style buildings also have a nice atmosphere! This is a spot where you can relax and enjoy the view from the large windows of the indoor bath, which has a bathtub carved out of stone.

“Hinatami Yakushi Footbath” is right in front of your eyes.

Hinatami Yakushido and footbath are right next to Gomuso no Yu. The temple was built to commemorate the birth of the hot springs, and is said to be where Yakushi Nyorai, who is said to be able to cure all ailments, is enshrined as the hot springs healed injuries and illnesses. It might be a good idea to visit the hot springs after visiting Yakushido.

[One-day hot spring] Enjoy the high-quality architecture and hot springs at the long-established “Sekizenkan”

Sekizenkan, located in the Shinyu district, is a long-established inn founded in 1694 (Genroku 7). As Japan's oldest and rare hot spring inn building, it has also been designated as an important cultural property of Gunma Prefecture. In addition to staying overnight, we also offer day-trip bathing, so be sure to give it a visit.

On the red bridge leading to the inn, there is a stately building... Expectations are high for the exterior, which is reminiscent of Hayao Miyazaki's ``Spirited Away.'' Call the receptionist, pay the 1500 yen day trip bathing fee (face towel and toothbrush included), and head to the hot spring!

Genroku no Yu (Important Cultural Property) was built in 1930. Five stone bathtubs are lined up in the hall-style bathroom, which lets in plenty of light from outside, and hot water gushes out from the bottom of the bathtubs. (Because large bathtubs were not common at that time)

Another attraction is that you can enjoy hot spring architecture from the early Showa period, such as the ``steam bath'' which is said to be the origin of baths, and the architecture where the dressing room and bathroom were integrated. After bathing, it might be a good idea to relax in the footbath or after-bath area.

[Accommodation] Enjoy 3 private open-air baths! "Kashiwaya Ryokan"

Kashiwaya Ryokan , which has a modern Japanese atmosphere, is a place where you can enjoy hot springs while staying overnight. There are three private open-air baths that guests can use free of charge, so you can enjoy bathing in a private space without worrying about anyone seeing you.

The large public bath with beautiful light shining through the stained glass has an open and attractive feel. There are so many baths that you might want to take a bath in, so it can be confusing.
