Do you know this Raku vase artist's seal mark?

I bought this at a flea market. It has a tiny chip but I love the colors. At least believe it is raku and Japanese? Do you know the seal mark? It measures about 3.5 inches by 5 inches. The bottom is different that any vase I've seen. Thank you.

 

I don’t know anything helpful(but others will) But I really like this,different and very cool. Never see such a bottom. Looks to have age. Nice buy!

 

Yes, thank you. I usually will not touch anything with a chip but this was too lovely.

 

Am I to assume no one else saw this or knew about it?

 

I'm assuming most of us don't have anything pertinent to add. The base is quite different from the usual flat base. I think it is a nice piece of studio pottery. You might be able to find someone to decipher the "chop" mark. (Did you try google lens?) I dunno if it's Chinese or Japanese. However, it could be a piece of art pottery by someone we've never heard of.
