Yaizu Onsen serves one of Japan's most important fishing ports, where massive tuna and bonito fleets land catches that supply sashimi restaurants and katsuobushi producers across the entire country, making Yaizu Port a beating heart of Japan's seafood economy. The city also holds an unexpected artistic distinction as the longtime home of Ota Hisa — known in Europe as Hanako — the Japanese performer who modeled for the sculptor Auguste Rodin in Paris and maintained a decades-long correspondence with him that left a remarkable mark on European art history. The onsen's mineral-rich waters provide warm recovery after days spent at the fish market docks or exploring the unlikely international story that unfolded in this unassuming Pacific port city.

Insider tip — Yaizu is Shizuoka's major fishing port on Suruga Bay, landing some of Japan's finest bonito (katsuo) and tuna and home to a lively harborside fish market. The city's onsen draws bicarbonate-rich thermal water that locals have used for generations to relieve fatigue after long fishing voyages. A post-market breakfast of tataki-style bonito sashimi followed by a mineral bath makes for an authentically local Shizuoka morning.
