Arima Onsen nestled in the mountains above Kobe is one of Japan's three oldest hot springs, with records of therapeutic bathing dating to the 7th century. What makes Arima truly unique is its two entirely different types of spring water: the rust-orange kinsen (gold spring) rich in iron and salt, and the clear ginsen (silver spring) with carbonated and radium waters. Just 30 minutes from Kobe, this charming spa town of lantern-lit alleys and traditional craft shops offers a world apart from the city below.

Frequently Asked Questions
How do I get to Arima Onsen from Kobe or Osaka?
From Shin-Kobe Station, take the Kobe Municipal Subway Seishin-Yamate Line to Tanigami, then the Kobe Electric Railway Arima Line to Arima Onsen — total about 30 minutes (¥720). From Osaka Umeda, take the Hankyu Line to Takarazuka, then change to the Kobe Electric Railway for about 60–70 minutes total (¥850). Direct buses from Osaka (Shin-Osaka, Umeda) and Kyoto also serve Arima, taking about 70–90 minutes. Arima is also directly accessible from Kobe Sannomiya by express bus (40 min, ¥900).
What is the difference between gold and silver springs in Arima?
Arima has two entirely different types of spring water. Kinsen (Gold Spring) is iron-rich and saline — the orange-brown color comes from iron minerals that oxidize on contact with air. The water is said to relieve fatigue, rheumatism, and poor circulation. Ginsen (Silver Spring) is colorless and carbonated — it contains radium and carbonic acid, distinctly cooler and different in therapeutic effect, believed to improve skin and circulation. Most Arima ryokan have both types. The two public baths — Kinnosyu and Taiko no Yu for gold, Ginsensui for silver — allow day visitors to try both for under ¥1,500 total.
Is Arima Onsen a good day trip?
Arima is a comfortable day trip from Kobe (30 min), Osaka (60–70 min), or Kyoto (90 min). Day-trip visitors can use the public bath houses — Kinnosyu (¥650), Taiko no Yu (¥800), and Ginsensui (¥550) — without staying at a ryokan. The narrow streets with craft shops and Arima senbei crackers can fill 2–3 hours of browsing. For the full experience, an overnight ryokan stay with dinner and private baths is recommended — the town is most atmospheric after the day-trippers leave in the afternoon.
What should I eat in Arima Onsen?
Arima senbei (有馬煎餅) are the town's signature snack — light, crispy rice crackers with various flavors including sesame and gold flake, perfect for omiyage. Kobe beef is nearby and featured at many ryokan restaurants and the town's teppanyaki restaurants. Arima is also known for bamboo-woven crafts and chopsticks, and craft sake is produced locally. Most ryokan kaiseki dinners highlight seasonal Hyogo ingredients — fresh seafood from Akashi, mountain vegetables, and high-quality Kobe or Tajima beef.
What is the best season to visit Arima Onsen?
Arima is a year-round destination. Autumn (late October–November) is peak season for maple foliage on the surrounding Rokko Mountains — the forested hillsides above the town turn spectacular, but accommodation books up 2 months ahead. Winter (December–February) is atmospheric with fewer crowds and the gold spring is particularly soothing in the cold. Spring (March–April) brings cherry blossoms to the surrounding valleys. Summer can be humid but the mountain elevation keeps temperatures a few degrees cooler than Kobe or Osaka. Weekends are always busier than weekdays at this popular domestic resort.
