Visit Tsuboyu Onsen

Yunomine Onsen – Tsuboyu Onsen 1

This century-old onsen is the crown jewel of Yunomine Onsen. It’s said to be dated all the way back to the 12th century, making it one of the oldest baths in all of Japan. It’s situated in a small cabin on top of the creek that flows through Yunomine Onsen, and from its exterior all the way inside, there is this old-world vibe you can’t shake, making this onsen more special than the norm. 

Historically, it’s believed that the water here is extremely potent and has many health effects on the body. Hangan Oguri, a famous historical figure who was the son of a provincial lord, was said to have restored his health by bathing in these waters. It is also believed that the water changes color seven times a day here.

The process in order to bath here is that you need to purchase a ticket from the vending machine nearby. From there, you can exchange the ticket for a number at the nearby counter, and wait until it is your turn. There is only a maximum of 1-2 people allowed in at a time, so this is a great activity for couples or solo travelers. Once you get inside, place your clothes in a basket, rinse your body, and then enter the hot spring for some rest and relaxation. If it becomes too hot, turn on the tap for some cold water and mix the water with the stir tool provided. Every visitor is only allowed 30-minutes.

Have you ever heard of the Japanese cooking vegetables and other ingredients using the hot, hot steam from onsens? Well, you can experience this in person in Yunomine Onsen! Here, it is a popular activity to purchase some raw eggs and vegetables (which come with a net and rope) at the small local stores near the river.

After that, head to the Yuzutsu, the square ‘hell’ pit in the middle of the village. Tie all their ingredients inside the net and sling them into the hole, tied to a plank on a side, letting the food sink below the surface of the water.

Most people wait around for their food to be cooked (12-15 minutes), others walk around and go for a dip in the water or explore the street on food whilst they wait. Either way, when time’s up, simply lift your bag out of the water and you’re done!
