I have a set of teacups from sushi restaurants in Furubira, Hokkaido, that I received during the Showa era. They're retro! * Shinya Sushi * Iyo Sushi (now closed) * Kiku Sushi (now closed) They come with boxes. Only one teacup from Iyo Sushi is without a box. How about adding them to your collection? Recommended as antiques and retro items. Teacups from closed sushi restaurants are hard to come by.
