Outdoor BathNo

Open-air outdoor bath

Two independent recent reviews describe indoor-only baths (stone/wood, gender-alternating), and neither the official site nor any of the 5 Google reviews mentions an outdoor bath; one aggregator listing ambiguously flagged 露天風呂 in a generic feature-icon list but could not be verified as an actual statement about this facility, so it was not used.
