I have a set of souvenir cups purchased in Japan during the 1990's depicting Tokyo locales. There are no markings or production information, only the kanji depicted on the cup design.
To me, it looks like 缶田門. I suppose 缶田 phonetically could be Kanda, but as far as I know only 神田 is used.
Or could it be some some antiquated usage? Or something completely different?
