One of the must-have Japan holiday experiences is a therapeutic soak in a relaxing onsen (hot spring bath). It is common knowledge that the onsen is an important part of Japanese culture, and they have various curative benefits for the body. But other than enjoying the healing benefits of the hot spring water, there are many unique onsens in the country offering the wacky experience for extraordinary travel memories. Let’s discover these quirky onsens in the Land of the Rising Sun together!
It can be quite entertaining to watch the monkeys interact with one another in their large group, especially when you can observe them up close given there are no fences in the park. Like humans, the younger monkeys are typically more energetic and play freely in the bath, while the adult monkeys usually rest and enjoy the soak with their eyes closed. After watching the Snow Monkeys enjoy their onsen, warm yourselves up in the only Japanese onsen ryokan in Jigokudani just across the river at Korakukan. Who knows, the monkeys may just come to the inn’s open air bath and join you in your relaxing dip!

2. Hottarakashi Onsen in Yamanashi
Although it is no longer a free public bath, Hottarakashi Onsen has retained much of its original charm with the most breathtaking scenery you can imagine in Japan. Besides its strategic location atop Kofu Basin opposite from Mount Fuji, it is awesome that Hottarakashi is open daily one hour before sunrise, and only closes late at night. Not only does this allow you ample time to enjoy the hot spring, you should also go there early to admire the stunning sunrise. After that, you may enjoy a good breakfast in one of the on-site restaurants, explore the region for its picturesque scenery or go fruit-picking. Finally, return to the rustic onsen for the amazing night scenery. This is certainly one onsen that you feel like soaking in forever!

3. Kawayu Onsen in Wakayama
The pure spring water at Kawayu Onsen has a high temperature of about 73 degree Celsius (about 163 Fahrenheit). Due to its strong acidic nature, it is said to be good for the skin because of its bactericidal effect. But because of this, the water is unfit for circulation pipes as it will corrode the metal, hence all the hot springs in the town are flowing freely. If you happen to pass by the town, don’t miss the chance to enjoy a free quick soak! Kawayu Onsen is good to visit any time of the year. If you visit during the winter months, join in the fun at the Sennin-buro River Bath, a giant outdoor bath that literally means 1,000 people can bathe at the same time in the steamy onsen.
Kawayu Onsen (川湯温泉)
Address: Kawayu, Hongu Town, Wakayama Prefecture
Price: Free for baths in the river. 250 JPY (2.40 USD) for Kawayu Onsen public bath.

4. Shyosenkaku Onsen in Nagano
Besides the unique made-for-monkey onsen in Nagano Prefecture, there is another amusing onsen in the prefecture - Shyosenkaku Onsen (中尾山温泉 松仙閣). This is an open-air bath with a matchmaking facility, a novel concept in Japan. There is a matchmaking shrine surrounded by a window, separating the male and female bath. The window can only be opened from the female bath using a string attached to the window. Once a lady guest who is game to try this facility pulls the string, she will be able to see a little bit of the other bath and get to chat with her “match” if she likes who she sees.
It is said that there have been three couples who have walked down the isle since they got to know each other through this quirky matchmaking concept. Of course, whether you are really successfully match-made in the end depends on your luck. Nonetheless, this can be a fun way to add some spice to your orthodox hot spring bath in Japan. You never know if this could be your golden opportunity to meet the right one!
Shyosenkaku Onsen (中尾山温泉 松仙閣)
Address: 2475 Shinonoi Komatsubara, Nagano Prefecture
Price: 650 JPY - 6.20 USD) per adult.

Every year in winter, the annual Lake Shikaribetsu Kotan event will be held in the highest-elevation lake of 801 metres (2,657 feet) in Hokkaido’s Shikaoi City.
