Spend a day enjoying the quality hot spring of Zao Onsen.
Zao Hot Spring is said to have been found in AD 110 and beloved for almost 1900 years. This bathhouse offers a place to stop by and enjoy the hot spring of Zao. The water is strongly acidic and sulfuric which is effective to rejuvenate the skin and blood vessels as well as improving skin’s antiseptic properties and strengthening the skin, cherished as “the Beauty Water” since ancient days.
This bathhouse has the tubs close to the abundant in-house source spring, always providing ample amounts of fresh hot water. The hot spring is generously flowing in the outdoor bathroom surrounded by nature and in the elegant indoor bathroom fragrant of cypress. The large outdoor bath surrounded by rich greenery feels like it is in the middle of a forest, so comfortable that you tend to stay longer than you planned.
2-in-1 shampoo and body soap are provided in the bathrooms and hand towels (sold) and bath towels (rental) are available. You can casually stop by empty-handed.

I really love Genshichi Roten no Yu! I visited during the autumn leaves season, and the sulfur hot spring flows directly from the source. The spring water comes straight from the mountain top—so nice!
I really love Japanese hot springs, especially this one! No matter how many times I come, I never get tired of it! 🤣
Genshichi Roten no Yu—I really like the hot springs here. The large open-air bath is filled with milky white sulfur water, and the little white mineral flowers are blooming. I had a super relaxing soak. It was fantastic.
This hot spring in the Zao Onsen area of Yamagata is my absolute favorite ♨️. There's both indoor and outdoor baths—highly recommended! You really have to come and experience these hot springs for yourself ♨️👍
