川中島温泉テルメドーム

Great hot spring, spa, and sauna complex in Kawanakajima, priced JPY950 for weekdays and 1,000 for weekends within tax. Also body massage, scrubbing, and restaurant are available. Always crowded even on weekdays, I don’t recommend to visit on weekend if you want to get settled. Later payment, credit card, some e-money and QR code payments are accepted. Huge car parking lot is available.

The people working there went way and beyond to help us have a good time and to get a taxi back home.

Fantastic hot spring with the most powerful jet massage bath I ever experienced… wonderful

Clean and new, wonderfully relaxing bath and great menu selection at the restaurant.

English is ok, baths are brilliant, hot, cold, jet, warm, outside, inside, electrified (like a massage type thing). Restaurant is nice. Has massages available and the Korean thing where they scrub the hell out of ya. And it's connected to pretty much a child care center and a fitness room+studio with lots of programs (mostly cardio/zumba stuff but one new weight lifting program)
