Ichi no Yu, The Landmark of Kinosaki Onsen
Ichi no Yu is located in the middle of the hot spring town in front of the Ōbashi Bridge (王橋). It is the landmark of Kinosaki Onsen. The building is so magnificent that many mistake it for a Kabuki Theater (歌舞伎座)!
Remember to walk past Ichi no Yu at night, again. Both the Ōbashi Bridge and Ichi no Yu’s building are lit up, which makes the bathhouses appear extra majestic.
Because Japan’s Father of Hot Spring Medicine praised the hot spring source here (Arayu, 新湯) as the best in the country (天下一の湯) in 1734, the bathhouse was named Ichi no Yu. This is also why the stone monument in the small garden beside the bathhouse has the phrase Kainai Daiichisen (海内第一泉) written. As expected, Ichi no Yu is one of the most visited public bathhouses in Kinosaki Onsen.
In addition, probably because the word “First (Ichi, 一)” is in the bathhouse’s name, the onsen here is known as the hot spring that helps you pass exams and bring you good fortune (合格祈願・開運招福の湯).
The bathhouse is most renowned for its cave bath. Some even said that being surrounded by rocky surfaces while indulging in the warm onsen simulates being in a mother’s womb.
After enjoying the hot spring, you can continue relaxing on the second floor. The floor is heated for the guests to lie on all year round!
Tip: There may be a queue on weekend evenings at Ichi no Yu. A morning bath is recommended.
What to Bring to Ichi no Yu
Like other bathhouses in Kinosaki, the amenities at Ichi no Yu are limited. Shampoo and body soap are available in the shower area. However, no toner or lotion is provided.
Also, towels are only provided for a fee. We paid 200 yen for a regular towel for the visit. A bath towel can also be rented.
Ichi no Yu’s Cave Bath
The bathhouse’s cave bath was created utilizing the natural rocky hill. Soaking in the onsen in the semi-open-air bath while feeling the rugged rock surface will make you feel as if you are bathing in the wild. It is both relaxing and spiritual to bathe here.
The cave bath has a capacity of a maximum of 15 people. As it is semi-open-air, you can enjoy it even on a rainy and snowy day. The rock ceiling will shield you from the snow so it won’t accumulate on your head!
Moreover, this outdoor bath generally has the perfect bath temperature if you don’t usually take scorching hot showers.
The Private Onsen Tub at Ichi no Yu
If bathing with strangers isn’t your cup of tea, you can pay extra to utilize Ichi no Yu’s private onsen on the second floor.
The Hand and Foot Spa Next to Ichi no Yu
If you don’t have time to bathe in a bathhouse, how about spending a couple of minutes at the hand and foot spa next to Ichi no Yu’s stone monument?
While foot spas are commonly found in Japan’s hot spring towns, not many have one that also has a hand spa. Especially on a cold winter day, this little spot is gold to warm you up!
The facility is free to use but popular. Thus, it may get crowded. If there aren’t many people at the hand and foot spa, take off your shoes and put your tired feet into the hot spring before resuming your exploration of Kinosaki Onsen again!

The Hot Spring Drinking Fountain in Front of Ichi no Yu
There is also a drinking fountain across the road beside the Ōbashi Bridge. You can use it to wash your hands, and the warm water will smoothen your skin, too!
As there are no cups around, use your water bottle or your hands to taste the onsen. The hot spring flows continuously, so there is no hygiene issue.
It has a slightly salty taste.
