Kumagaya Hanayu Spa Resort
One of the largest spa complexes in Saitama, in Kumagaya in the north of the prefecture. Its own alkaline simple spring, pumped from 1,500 m at over 600 litres a minute, feeds a wide range of tubs — a free-flowing open-air 'raw source' bath, pot baths, lie-down baths and a high-concentration carbonated bath. There is a löyly sauna, cold plunge and a garden-view outdoor rest deck. The optional 'Onkatsu Café Nest' adds eight kinds of bedrock-bath rooms, manga and free drinks for an all-day stay. Admission ¥950 on weekdays, ¥1,100 on weekends and holidays; open 10:00–23:00 (last entry 22:30), no closing days. Private rooms with an open-air pot bath can be reserved by phone. About 10 minutes by bus or taxi from JR Kumagaya Station; 300 free parking spaces. Kumagaya is about 40 minutes from central Tokyo by Shinkansen — combine with rugby at the stadium or Menuma Shōdenzan temple.
