男湯は大丈夫。ただ見える所にある、自分はタトゥー無しでも連れがタトゥーだとわかると受付の人がしつこく見にきます。隣の薬局のおかみもタトゥー嫌いらしくうるさいです。

I sent my husband without a tattoo because I could not enter, and I waited, just when my aunt came over again and again.

About the tattoo it was absolutely forbidden, big and small. Even if it was completely hidden by a seal etc, it was NG.
