Healthy Spa Sunroad Shimobe-no-Yu is a day spa in Minobu, Yamanashi Prefecture, offering a distinctive combination of hot springs, fitness, dining and relaxation in a scenic mountain setting. The facility is recognized by Japan’s Ministry of Health as a health promotion facility that supports the safe use of hot springs and exercise. Its baths draw on two different therapeutic springs: the high-temperature Shimobe Okunoyu source and the cooler Amagawachi source, associated with the historic Shimobe Onsen area, known as one of Takeda Shingen’s hidden retreats.

Guests can enjoy spacious indoor and open-air baths, a Finnish-style löyly sauna, a cold plunge, walking bath and reclining bath. Additional amenities include a relaxation room with massage chairs, a changing area and a free outdoor footbath. Fitness facilities and relaxation treatments complement the bathing experience.

On-site Healthy Restaurant Parsley serves meals and local specialties, including Yamanashi Gensui ramen, alongside seasonal dishes. The spa welcomes visitors daily, with longer morning access on weekends and holidays, and offers admission options for local and out-of-town guests
