The Japan Self-Defense Forces have carried out a variety of lifesaving and support activities since the 3.11 disaster. Not many people know that they provided bathing facilities for people who were experiencing a protracted evacuee life. The JSDF set up its temporary bathing equipment called ‘Field Bathing Set Mk.2’ at 42 different locations. A tank car pumps up water from the river, filters it, and then heats it for 45 minutes to provide 5.4 tons of hot water per hour. It allows 30 people to shower at the same time and 1,200 people to take a bath per day. The baths had a great healing effect on those forced to escape from the tsunami and the nuclear accident with just the clothes they were wearing. This mobile bathing service is unique to Japan with its traditional bathing culture.
