Overview
Arima Onsen is recognized as one of the "Three Ancient Springs of Japan," alongside Dogo Onsen in Ehime and Shirahama Onsen in Wakayama. Its history is said to date back to the age of myths and is mentioned in the "Nihon Shoki," Japan's oldest official history chronicle. It has been cherished by many historical figures, including Emperor Jomei and the powerful warlord Toyotomi Hideyoshi.
Located on the northern slope of Mt. Rokko, it is conveniently accessible, about a 30-minute drive or train ride from central Kobe. The town itself has a charming, traditional atmosphere with its winding narrow streets and hills. Visitors can enjoy a stroll through the steamy townscape, experiencing both history and nature.
The most unique feature of Arima Onsen is that its hot springs gush from a depth of 60 km, despite the absence of a volcano. The waters are broadly categorized into two types based on their mineral composition: "Kinsen" (Golden Spring) and "Ginsen" (Silver Spring).
Main Spring Qualities and Indications
Arima is famous for its "Kinsen" and "Ginsen" springs. Kinsen is an iron-rich [Iron-rich spring] and [Chloride spring] that is clear when it emerges but turns a distinctive reddish-brown as the iron oxidizes in the air. Ginsen is a clear, colorless water, categorized as either a [Carbon dioxide spring] or a [Radioactive spring], known for its refreshing feel.

Water Characteristics and Best Season to Visit
The source temperature in Arima is extremely high, reaching up to 98°C (208°F). Thanks to the abundant flow, many facilities offer gensen-kakenagashi (free-flowing spring water), though some may add cool water to regulate the temperature. The high salt content of Kinsen is excellent for heat and moisture retention. Ginsen is said to help improve blood circulation.
While enjoyable year-round, autumn (around November) is particularly spectacular when the fall foliage of Mt. Rokko paints the town in vibrant colors. Winter also offers a magical experience, soaking in a hot bath amidst a snowy landscape.
