Onyado Nono

A chain rule, with the largest seals of any chain — when they are in stock

Onyado Nono is Dormy Inn’s ryokan-styled brand, and its FAQ page gives the chain’s answer word for word: refused in principle, but a tattoo that a cover seal hides completely may bathe. Three seal sizes — 85×105, 100×140 and 118×172 mm (4.6×6.8 in) — and two per guest, so two large ones cover about 400 cm², the most of any chain on this site.

The same FAQ adds that seals are provided “depending on the facility” and that “stock is limited”. Bring your own of the right size and the rule works in your favour every time.
