The shared bath is linked as sister ryokan Rantei's onsen; the facility itself is branded 秋保温泉蘭亭 (Akiu Onsen Rantei) throughout the site. It is unclear whether each room's own private in-room bath is fed by real onsen water (see gaps).

Each dome-tent room has its own private open-air bath on its deck.
Enclosed indoor bathing area
Guests can also use the large indoor communal bath at the on-site sister ryokan Rantei, free of charge (15:00-25:00, 5:00-9:00).

ForestAbout
GLAMPSEASON is a glamping resort in the forest above Akiu Onsen, a short drive from Sendai. Each dome-tent room sits on its own wood deck with a private hinoki (檜) cypress bath and a shower room, so bathing is on your own schedule with nobody else around. Guests also have free run of the large indoor bath next door at sister ryokan Rantei, fed by the Akiu hot spring. The stay revolves around a BBQ dinner cooked at your own deck (Miyagi wagyu is the main event), a poolside Finnish-style sauna you can reserve for a private session, and a free guest lounge stocked with manga and drinks. A few rooms allow dogs, with their own dog run out front.
