As the step numbers are written on each, it's common for visitors to work out which step corresponds to their own birthday and take a commemorative photo on it. There are 3 free footbaths at the bottom, middle, and top of the stone steps, perfect for soaking in between strolls!

Our Top Tips

JR Pass for Whole Japan

Explore Japan in the most convenient and economical way with a Japan Rail Pass! It is valid for the majority of railways and local buses operated by JR. 

Both sides of the steps are lined with unique stores, such as retro shooting shops where you can play with cork guns to hit prizes like toys and sweets and ones selling manju buns, a traditional sweet made by wrapping red bean paste boiled in sugar in a thin dough and steaming it. Ikaho Shrine, located at the very top of the stone steps, is a popular shrine to pray for good luck in love and marriage. At night, the stone steps are illuminated in an enchanting display.

There are two types of hot spring water in Ikaho Onsen: the "Golden Hot Spring," which is actually more brown and contains calcium and sodium, and the "Silver Hot Spring," which is clear, odorless, and suitable for those recovering from illnesses. There is a beautiful vermilion red bridge near the source of the Golden Hot Spring, which is about a 15-minute walk from the stone steps and a famous spot for lush greenery and autumn leaves.

Shima Onsen: Straight Out of a Ghibli Movie?! (Gunma)

Shima Onsen is a deeply historical hot spring resort with 1,000 to 1,200 years of history and a legend that it can cure 40,000 diseases. The hot spring water here is said to be good for the digestive system when drunk and great for the skin when bathed in, which explains the many drinking fountains available. With numerous inns utilizing seasonal ingredients to craft exquisite Japanese dishes, visitors can get a taste of tradition through local cuisine alongside its atmospheric streets.

Ghibli fans will also love how Shima Onsen’s Sekizenkan Ryokan looks like the bathhouse in the hit Ghibli anime "Spirited Away." In fact, many of the town’s hot spring inns with 300+ years of history bear a striking resemblance to those in Spirited Away.

With the Hinata Miyakushido shrine and Lake Okushima nearby, Shima Onsen is the ideal place to appreciate the fresh greenery and vibrant fall colors of Japan.

Kusatsu Onsen: Japan's Largest Natural Spring Water Yield with Antibacterial Powers! (Gunma)

The Yubatake is the symbol and heart of Kusatsu Onsen. It has a high acidity level of pH 2.1 and a hot spring water output of 3,000 to 4,000 liters per minute! The source of the hot spring is located right in the city center of Kusatsu, and is lit up in a magnificent display come the evening.

When exploring Kusatsu Onsen, a visit to the hot spring facility "Netsunoyu" to see the tradition of "yumomi" should not be missed. Yumomi is a method of lowering the temperature of Kusatsu's extremely hot spring water, which can range from 50°C to 95°C, by stirring it up without diluting it. Visitors can watch the jovial song and dance performance that accompanies the stirring of the bath, and you can even have a go at it yourself!

Another recommended spot is Sainokawara Park, a 10-minute walk from Yubatake. The park is filled with greenery and natural hot springs gushing out from the ground, providing the ultimate onsen landscape. There are also free foot baths with different temperatures depending on the location, so choose one just right for you for a relaxing soak. Just don't forget to bring your own towel!


Nasu Onsen: Nature, Theme Parks, and 1,300 Years of History! (Tochigi)

Nasu Onsen is located in a highland resort close to renowned sightseeing spots like Komagataki, famous for the amusement park Nasu Highland Park and stunning autumn foliage, as well as Mt. Chausu, which can be ascended via ropeway.

While there are lots of accommodation facilities including ryokan (traditional Japanese inns), resort hotels, and guest houses, as well as various hot springs scattered throughout the area, we recommend visitors take a dip at Shikanoyu, which has a 1,300 year history. The wooden building was built in 1936 and, while being clean and well-maintained, one can definitely sense its long history.

Shikanoyu, which was said to have been discovered from deer healing their wounds in the water, has a special bathing method called "kaburi-yu." Before hopping in, bathers are meant to use a “hishaku” (a Japanese water ladle that has a small cup with a long handle) to pour hot water over the back of the head and neck 200 times for adults and 100 times for children. This ritual is said to increase the effect of the hot spring and to prevent people from getting dizzy when bathing. The hishaku is free to borrow, so don't hesitate to give it a try! The spring is a plain acidic sulfur hot spring, filling the area with the smell of sulfur typical of a hot spring resort.

Kinugawa Onsen: Hot Springs by a Magnificent Valley (Tochigi)

Kinugawa Onsen is a hot spring resort boasting hotels and ryokan dotted along a stunning valley. The gentle spring water has a weak alkalinity and is said to be effective for burns.

There are plenty of sightseeing activities in the area, such as visiting the Edo Wonderland Nikko Edomura, a theme park that recreates the streets and lifestyle of the Edo period (1603-1867), or enjoying a boat ride down the valley river.

Another must-see in the area is Nikko Tosho-gu Shrine, a UNESCO World Heritage Site. It has a history of approximately 400 years and is chock full of gems to discover and appreciate, including the magnificent gate and exquisitely detailed sculptures.
