💡 Tips for Visitors

The water is extremely hot and acidic, so limit your initial bathing time to 5-10 minutes and rinse off afterward. Cash is typically required for entrance fees as card payment may not be available. English signage may be limited, so familiarize yourself with basic onsen etiquette beforehand, including bathing nude in gender-separated areas.
