? Japanese mark

Hello, if anybody knows whose mark this represents, please would you let me know? Thank you very much.
It is on a small pot (as indicated by hand and satsuma), and on the side only. There is no mark on the base.

It could well be a Japanese sake cup (guinomi in Japanese) but other images would help.

Looks like Bizen ware, which is unglazed pottery from the Bizen area in Japan; the colour is from the natural ash produced during firing. The stamp would be kanji characters but I’m afraid I can’t read then

Bizen is one of the 6 Ancient kilns of Japan and today in and around Bizen City there are hundreds of kilns.

As Naomi says, the mark shows Japanese characters (kanji). I don't read Japanese but, if you were a native Japanese speaker then the likelihood is that you would not be able to decipher it either.

The mark is a kiln mark, i.e. showing in which kiln the sake cup was fired. In Bizen pottery an individual potter's mark is almost always an incised mark.

The stoneware body suggests that it is relatively modern, as it isn't the smoother more tradition stoneware that has been used from ancient times.

Thank you so much for that, Naomi and studio-pots. I'll try and discover which kiln it was.

Thank you potterymad62, that was a very interesting link to use and know.
