I don’t know if this is the right community to ask about this. I’ll delete the post if it’s not.
I got this tea set at a thrift store today and I tried to look up the makers mark out of curiosity, but I’m awful with kanji and I havent been able to get any online tools to help figure it out. I know it’s probably not anything special, but I’m still curious.
I think it’s a ware mark. The calligraphy used can make the kanji neigh illegible even for native Japanese readers.
