Sauna Fuji — Sakae's Retro Capsule-and-Cold-Pool Sauna

Down a side street off Nishiki-dori in the middle of Nagoya’s Sakae district, behind an unassuming entrance, is a building that’s been quietly perfecting one very specific combination since long before “sauna” became a buzzword: brutal heat, immediate cold, repeat. Sauna Fuji is a men-only capsule hotel and public bathhouse built around a genuinely oversized cold plunge pool, wrapped in a Showa-era retro atmosphere that a 2022 renovation cleaned up without sanding off the character.

Why It’s Interesting

Most sauna facilities offer a cold shower or a small tub; Sauna Fuji has a 20-meter-long, 110-centimeter-deep pool, reportedly the largest of its kind in the area, alongside a 100°C main sauna room. Upstairs, 368 capsule rooms stack the building into one of Sakae’s largest capsule hotels — enough that regulars use it as a business-trip base as much as a bathhouse. The retro tilework, low lighting, and unhurried Showa-era pacing give it a genuinely different feel from Japan’s newer, minimalist sauna boom spots, while the 2022 refresh kept it clean and comfortable rather than nostalgic-for-nostalgia’s-sake.

Best Time to Visit

Open 24 hours, so there’s no bad season — locals favor late-night or early-morning sessions when the bath floor is quietest. A ¥1,000 late-night surcharge applies after 2am if you’re still inside.

Getting There

About 5 minutes on foot from Sakae Station on the Nagoya Municipal Subway (Higashiyama and Meijo lines): from Exit 8, walk west along Nishiki-dori and turn at the third traffic light. It also sits directly on Nagoya’s well-known Horikawa River running route — many runners follow the river greenway down through Meijo Park and Kanayama, then cut over into Sakae to finish here, sauna and cold plunge doubling as the reward lap.
