Escape to Natural Hot Spring Spa Royal Kawaguchi, a Balinese-themed retreat easily accessible from JR Akabane and Kawaguchi stations via the International Kogyo Bus (get off at Hinotsume) or a 10-minute walk from Saitama Rapid Railway's Minamihatogaya Station. Open from 9 AM to 1 AM (6 AM to 1 AM on weekends and holidays), this spa offers a variety of baths, including a natural hot spring drawn from 1300 meters below ground, known for its sodium-chloride properties. Enjoy the unique black waters, said to have a slightly viscous texture, alongside amenities like a sauna, bedrock bath, and relaxation spaces. Note that the facility occasionally undergoes maintenance closures twice a year. With its South Pacific atmosphere, diverse bathing options, and convenient access, Spa Royal Kawaguchi provides a relaxing getaway for locals and tourists alike.
