First visited this place about 5 years with an aquaintance and an old classmate from college who was visiting Japan. Most non-Japanese would be hesitant about walking around a public bath completely naked around other women but I really didn’t mind. I even brought my mother, aunt and cousin when they visited and they ended up enjoying the experience. The hot springs water used are from the Hakone and Atami areas and hauled in every day. There’s also a steam sauna, regular sauna and a salt sauna where you can scrub off the dead skin cells on your body with salt. The amenities offered are great as well. There’s even a free shuttle service that runs hourly between Manyo and Yokohama station(near the West Gate). The foot bath on the 9th(roof) floor has an amazing view of Cosmo World as well as the port of Yokohama(especially at night!). Great place to spend the day soaking up the hot tubs and relax.
