Bathing indications
The outdoor-bath page lists general indications including neuralgia, muscle pain, frozen shoulder and joint pain. These are not a guarantee of medical benefit.
The facility had a temporary tub-cleaning and inspection closure on April 22–23, 2026; those dates have passed. Fuji Rock early hours were also special event hours, not the usual schedule.
How to read a bath profile
