I visited this location June 23 of this year and I have tattoos on my arms which were clearly visible upon arrival and I was not turned away. The robe covered everything when I was buried. And the hot bath (which only fits about 3 people) after the sand bath is optional. I was in Japan for about 3 weeks and always wore short sleeve shirts and my tattoos were very visible. We visited many small restaurants and shops and not once was I ever turned away.

My 6 and 7 year old children were also with us when we went to the sand baths and the attendants accommodated to the adults first and leaf the children with only about five minutes. The kids loved the five minutes they spent buried in the sand but by minute four they were telling me they were getting to hot and wanted to scratch their noses.
