Mizuhashi Onsen / Gokuraku no Yu, located in Toyama, draws sodium-chloride water at 41°C. The facility offers an indoor bath, an outdoor rotenburo, and a sauna for a relaxing stop near Toyama Bay.
Insider tip — Gokuraku no Yu, the Paradise Hot Spring, serves the Mizuhashi coastal district of Toyama City where Toyama Bay opens to the Sea of Japan beneath the Tateyama Range, a wall of peaks rising 3,015 metres from sea level in one of the world greatest elevation gradients. Toyama Bay is famous for hotaruika firefly squid that glow bioluminescent blue in mass spawning events each spring along the shore.
