If you plan to travel to Japan’s Kansai region and want to visit an authentic hot spring town, Arima Onsen in Kobe should be your top choice. It is Toyotomi Hideyoshi’s favorite onsen! The mineral quality of the hot spring here is excellent, as it contains seven of the nine main components listed by the Ministry of the Environment as present in recuperation or recovery springs. In addition, the hot spring town has two completely different types of hot springs. One of Arima Onsen public baths, known as Kinsen (金泉), or gold spring, has a reddish-brown colour and contains iron and salt. Its salt concentration is twice that of seawater, forming a thin film that keeps your skin moisturized. It is also good for low back pain and muscle/joint pain.
Important: Kin no Yu is closed for maintenance from January 7, 2026, to late March 2026.
About the Public Bathhouse, Kin no Yu (金の湯)
When you come to Arima Onsen, Arima Onsen Kin no Yu spa is definitely the bathhouse you should visit. It is located at a three-way junction near the main street, Yumotozaka, and opposite the Arima Toy Museum.
Each gender has a separate onsen pool: Ichi no Yu (一の湯) for men and Ni no Yu (二の湯) for women. Unfortunately, like most public bathhouses in Japan, there is no private onsen pool you can rent. Instead, there is a free foot spa next to Kin no Yu onsen that you can utilize when the bathhouse is open.
Tip: Make sure you rinse your body after you get out of the onsen pool so the brown iron components in the hot spring don’t turn your clothes a different color (=ﾟωﾟ)ﾉ.
As you enter the onsen pool, you will find the hot spring is really cloudy, almost like a lot of chocolate has melted in the pool, so that you can’t see your arms or legs at all (´▽｀*).
You might find that the water gushing into the onsen from the spring is transparent. Please don’t mistake it for the staff adding normal hot water to the pool. The iron minerals in the hot spring only turn brown when they come into contact with air.
Because of the richness of the minerals in the onsen, it is not recommended that you indulge yourself there for too long. As a rough guide, 15 minutes is the maximum time you should spend in the pool.
Note that the temperatures of the two pools in both male and female areas are different. One is at 44 degrees, and the other is at 42 degrees. Pick the best one that suits you (^_-)-☆.
Taikō’s Hot Spring Drinking Fountain (太閤の飲泉場)
Because of Toyotomi Hideyoshi’s love for Arima Onsen, you will see many attractions named after and/or related to him. This drinking fountain, which is part of the Kin no Yu spa, is one of them. And when we say “named”, it is the last government position he obtained – Taikō (太閤) in his life. So instead of Hideyoshi’s Drinking Fountain, it is Taikō’s Drinking Fountain.
Note that you might expect Kinsen to come out of the fountain, but as Kinsen is only suitable for bathing, the fountain connects to Ginsen’s hot spring source.
The gourd above the spring outlet wasn’t chosen at random as a decoration. It is a symbol of Hideyoshi. Not only here, but as you stroll around the onsen town, you will also find many more gourds!
Tip: Avoid weekends and public holidays as they can be crowded.
