The water
Water is drawn from the Bandaiko source: one reviewer states it is piped from the strongly sterilizing Bandaiko gensen and warns that cuts and sensitive skin will sting badly; another notes the bath sits nearest to Bandaiko. Two further reviewers independently describe the water as strongly acidic.
