Arima Onsen 2027: Complete Guide to Kansai's Oldest Hot Spring

Arima is older than Kyoto. It is one of Japan's three ancient onsen (nihon san-ko-sen) with records dating to 631 AD, famously visited by Toyotomi Hideyoshi, and the one onsen town you can reach from Osaka Umeda in 30 minutes by direct bus. The water comes out of the earth two colours — reddish-brown iron-rich kinsen and clear carbonated ginsen.

Quick facts: Arima Onsen 2027

The two waters serve different purposes. Kinsen is the hotter mineral-dense red-brown water famous for skin + joint benefits. Ginsen is the carbonated clear water for circulation. Most ryokan have both. The town itself is a 20-minute stroll of narrow stone-paved lanes, soy-sauce senbei shops, and sake breweries.
