Behind Kokusai-dori: one of Okinawa’s few super-sento with genuine spring water
Okinawa has no volcanoes and few hot springs, but “Rikkarikka-yu”, attached to the Naha Central Hotel behind Kokusai-dori, is one of the rare genuine ones, drawing sodium chloride water from 800 m underground. The name means “come on, let’s go” in Okinawan. Two halls, Shiunsen and Togensen, alternate daily between men and women, each with an open-air-style tub of pale-brown moor water, jet and electric baths, three saunas (dry, salt, mist), a 17–18 °C cold plunge and a stone sauna — a mainland-style super-sento that tops Naha and ranks third in Okinawa in sauna-fan polls, a true base for local enthusiasts. Open 06:00–23:00 even on weekdays, it suits early arrivals wanting a wash or travellers unwinding before a night flight, and it is 5 minutes from Miebashi monorail station and 1 minute from Kokusai-dori — within 20 minutes of the airport by monorail. At about ¥1,250 on weekdays with your own towel it is reasonable for Okinawa; the facilities are a little tired, but reviewers keep mentioning the friendly desk staff and easy-going Okinawan mood. A good “anchor onsen” for the first or last day of an Okinawa trip.
Tips & cautions
- Pricing is complex (towels or not, weekday/weekend, time-band promotions) — check at reception. Raised since 2024.
- Dry and salt saunas open from 09:00 on weekdays (06:00 weekends/holidays); mist sauna from 06:00 daily.
- Lockers need a ¥100 coin (refunded).
- Only the open-air-style tub is spring water; the rest is heated tap water. Treat it as a sauna-plus-onsen package.
- Evenings and weekends fill with locals and the sauna queues — mornings are best.
- Tattoo rules may be restrictive, as at most super-sento — confirm first (098-867-1126).
- Free for hotel guests — worth pairing with a stay as your Naha base.
Getting there
