What Travellers Say
Reviews Summary
Visitors consistently praise Tsubo-yu for its historical significance as Japan's oldest onsen and its unique UNESCO World Heritage status. The experience of cooking eggs in the communal hot springs is a highlight, offering a fun and delicious interaction with the natural environment. However, some find the wait times for Tsubo-yu to be long, and the intense heat of the water requires careful management.
"You need to bring your own towel. There’s no queue for the public bath, but if you want to try the special blue onsen, you’ll need to purchase an additional ticket. The blue onsen allows 1–2 people at a time for 30 minutes per session. When buying the ticket, you’ll be informed of the wait time. You can also buy onsen eggs nearby."

"This is the oldest hot spring in Japan. Strong smell of sulphur in the area. It is also part of kumano kodo pilgrimage area. Pilgrims soaked here to purify themselves before visiting kumano shrines. The color of the hot spring water changes several times a day due to natural minerals. You are allowed to buy eggs at the nearby convenient stores and cook in the boiling hot spring water. It will cook in about 12 minutes. You can pay small amount of money to bathe in a tub of a tiny stone hut privately about 30 minutes per session, but it is a long wait."

"Great experience! Tsuboyu was quite an experience.
1) buy the tickets at the automated machine close to the normal onsen (800yen); the person there will give you a number
2) buy towels there or bring your own
3) line up (if necessary) according to the number you received
4) remember: shower before coming here, there are no showers
5) enter the barrack after taking off your shoes
6) check the water temperature: if it is too hot, you can use the massive water outlet to cool it down (recommended)
7) mix the water with the wooden stick
8) enjoy!
9) use the small warm water tap to fill the buckets and rinse yourself"
