I did mention the tattoo taboo, but I was only able to include this information about two Onsen (Zaboo & Oedo Monogatari) as they were the only places I knew for sure that banned them outright. It's just never been an issue for me. I'll be happy to update should anyone know of others that disapprove of body art.
I can then confirm that LaQua denies (indicated by quite cute, if incomprehensible, cartoons in the elevator and with accompanying text (in Japanese)) tattoo'ed bathers access to their facilities.
As a layover, it's absolutely excellent, except that one is usually unhappy when it's time to leave
