This is a great spa just 10 minutes away from the base, across the street from Mori Town Mall. The spa is on the 2nd and 8th floors of the hotel and has an English-speaking staff. This spa has just about any service you could want, including: deep-clean facials, oil facials, Thai massages, body wraps, manicures and pedicures. Prices range from ¥1500 for an individual service to a package for the day at ¥31000. Most massages range from ¥3500 to ¥8000.
DIRECTIONS: turn right out of the East Gate and stay on that road for approximately 10 minutes (depending on the time of day). You will approach Cainz, a big green building on the left that sells home goods. Pass Cainz and you will see an even larger sign for Mori Town Mall. Turn right on that street—if you pass the sign and reach a dead end you went too far. After turning, you will see a Forest Inn Resort sign. Turn into the second entrance and an attendant will be there. Just ask where to park for the spas services. Linda Frommeyer, 10/06. See comments below by Pam Tubbs.
