Karumaru Ikebukuro (かるまる池袋)

Opened December 2019. Four sauna types (stone, kelo, steam, firewood) plus four water baths — the Thunder Tornado is an ultra-cold jet flow bath. The Kelo sauna is built with rare Finnish wood and offers self-directed löyly. Unlimited manga, co-working space, and a restaurant on site. 30 seconds from Ikebukuro Station West Exit C6. Men only — keep that in mind.
