Arima Onsen

Arima Onsen sits about 40 km northwest of Osaka in the Rokko Mountains above Kobe, reached in 60-75 minutes via a combination of Osaka Metro, the Kobe subway, and the Kita-Osaka Kyuko line, or by taxi in 40-60 minutes for groups or those with luggage. One of Japan's oldest hot spring resorts, Arima is known for two distinct spring types: Kin no Yu (Gold Spring), an iron-rich reddish-brown water, and Gin no Yu (Silver Spring), a clear radium and carbonated water, each housed in its own public bathhouse. A relaxed day typically opens with a soak at Kin no Yu (about ¥650 entry) or Gin no Yu (about ¥550), followed by a walk through the compact onsen town's traditional streets, lined with craft shops, sake breweries, and vendors selling tansan senbei, carbonated spring-water crackers unique to the town. Nenbutsuji Temple, a small atmospheric temple in the hills above the town, and the Arima Toy Museum, a quirky collection of historic toys, both make good midday stops for visitors wanting a break from bathing. Many ryokan offer higaeri onsen day-stay packages, letting non-guests use hotel baths for ¥1,500-3,000, which is worth booking for a more private soak than the public bathhouses. Lunch is easiest found among the town's small restaurants serving Tamba beef and seasonal kaiseki-style set meals. Weekday visits are noticeably quieter than weekends, when day-trippers from both Kobe and Osaka fill the narrow streets and baths; the town suits either a half-day soak-and-walk or a fuller day combining both spring types and a temple visit.
