Steamed remaining fragile hibukuro (accordion inside) to reveal the original structure, kanji and painting. On 1-15-2024 Nick Cladis reported

“The kanji here is 倉嶋, which can be read "kurashima" or "kurajima" and is a surname.

The "rising sun" flag was used by the Japanese military almost right after the Meiji restoration (I think it was naval first, but I might be wrong), so it was used for a good 70+ years or so including the war. There are forms of the image (like the "asahi" sunrise icon/emblem) prior to Meiji, but this lantern clearly shows the red rays on a flagpole, so I would say it is no earlier than that.

Hope it helps! The cat / cartoonish imagery is really interesting. The lightness of those images counterbalances the intensity of the flag/nationalist icon, which may even be intentional. A place of business might utilize both... hey, we see this today, in our own country, in all kinds of branding.”
