Japanese studio pottery help, please

I thought it looked like crop circle figures (lol) Someone pointed out that it is Japanese studio pottery mark I was wondering if anyone here recognized it I am thinking this is at least MCM or older Any opinions are very welcome as I know nothing about this stuff! TYIA

 

Well my first thoughts as I was looking was California pottery. But the mark isn't Haldeman or Batchelder, who both made this turned lip shape. But not in a 3 point, theirs are 4.

I don't see Japanese characters.
Can you rub a little corn starch into the mark to see if any letters stand out?

Whoever told you Japanese, may be right, I don't know.

I'd say 1940s based on the California ones.

 

if you turn it 90 degrees to the left - could be NB.

 

I will try turning and corn starch and report back here. Ty for helping!

 

Could be Korean. That more rounded script looks Korean, and Koreans love celadon glazes.

 

While trying to look it up, I saw that Korea could be another possibility for it too. The owner was Japanese and had a lot of Japanese items but that’s not to say it couldn’t be Korean.

Does anyone think it’s a quality piece? I am clueless when it comes to this stuff!!

 

I do like it very much.

 

I have not been able to identify anything like it! UGH
