　“Shonan Natural Hot Spring Yunokura Garden” is a famous super sento accessible by free shuttle bus from JR “Hiratsuka Station” and Odakyu “Isehara Station.” It is especially known for offering one of Japan’s highest calcium-concentration hot springs without adding water. The facility also features sulfur springs, allowing visitors to enjoy two different types of hot spring water.

　One of the main attractions of this bath facility is the wide variety of baths available. There are 14 different bath types, including high-concentration carbonated baths, family baths, electric baths, powerful jet baths, jet baths, lower back massage baths, foot massage baths, cold baths, large open-air rock baths, sulfur springs, silky bubble baths, pot baths, bedrock reclining baths, and flowing spring benches.

　The facility also features a high-temperature sauna with multiple tiered seating levels, allowing guests to choose their preferred temperature zone. Another highlight is the automatic löyly service held every 15 minutes.

　The restaurant and relaxation area (with approximately 3,000 manga books) are also well-equipped, making this one of the most recommended super sento facilities in the Shonan area!
