What makes Arima Onsen unique in Japan — and indeed in the world — is the presence of two completely different types of hot spring water at the same location. Gold Spring (Kinsen / 金泉): The water emerges clear from the ground but turns reddish-brown when it contacts oxygen, due to its high iron and salt content. This is the famous "golden" water that Arima is known for. The salt content is extremely high — about 5 times saltier than seawater — which means the water clings to your skin after bathing, keeping you warm for hours. Effects: warming, moisturizing, good for fatigue recovery, muscle pain, and skin conditions. Silver Spring (Ginsen / 銀泉): Arima actually has two types of Silver Spring: a radium spring (radon water) and a carbonated spring. Both are colorless and clear. The carbonated spring is particularly rare — it's one of only a handful of naturally carbonated hot springs in the world. You can actually drink the carbonated spring water at designated spots in town. Effects: skin-softening, good for high blood pressure, arteriosclerosis (carbonated spring). Public Bathhouses: • Kin-no-yu (Gold Spring public bath): Adults ¥650. Open 8:00–22:00. Closed 2nd and 4th Tuesday. • Gin-no-yu (Silver Spring public bath): Adults ¥550. Open 9:00–21:00. Closed 1st and 3rd Tuesday. • Taikono-yu (large resort facility with both springs): Adults ¥3,300+. Open daily.

Practical Tips for First-Time Visitors: 1. Tattoo policy: Most public baths and ryokan in Arima do NOT allow tattoos. If you have tattoos, check with your accommodation in advance. Some facilities offer private baths (kashikiri-buro) that can be reserved. 2. What to bring: Towels are available for purchase or rental at the public baths. Most ryokan provide yukata (casual kimono) for guests to wear around town. 3. Etiquette: Wash thoroughly at the shower stations before entering the bath. No swimwear in traditional baths. Tie up long hair. 4. Day trip vs. overnight: Arima is excellent as a day trip from Kobe or Osaka, but staying overnight at a ryokan gives you access to the baths in the evening and early morning when they're least crowded. 5. English support: The tourist information center near Arima Onsen Station has English-speaking staff and maps.

Arima Onsen has its own unique food and souvenir culture. Must-Try Foods: • Tansan Senbei (炭酸せんべい): Thin, crispy crackers made with Arima's natural carbonated spring water. Light and slightly sweet, they're the quintessential Arima souvenir. Available at multiple shops throughout town, from ¥500 per box. • Arima beef: Local wagyu beef served at ryokan and restaurants. Not as famous as Kobe beef but excellent quality at lower prices. • Sake: The Rokko mountain area has good water for sake brewing. Several local sake brands are available in Arima. Shopping: • Tansan Senbei shops: Multiple shops sell these crackers, each with slightly different recipes. Try a few to find your favorite. • Bamboo crafts: Arima has a tradition of bamboo craft (take-zaiku). Baskets, containers, and decorative items make unique souvenirs. • Onsen cosmetics: Several shops sell skincare products made with Arima's mineral-rich spring water.
