Asian impressed mark or studio mark?

I'm baffled. Picked up an attractive, well made bowl ( 5" DIA, 3" high) thinking I'd be able to find the mark on Gotheberg ... but no luck even finding any similar marks. I don't believe it to be very old (just from the glaze pattern) ... and it isn't porcelain.

The glaze is matte gold, metallic dark gray, white and a bit of red with a crazed ivory interior. Originally thought it might be raku from the tiny black cracks on the edges of some of the glaze, but wouldn't the unglazed clay also be black?

Does the impressed mark actually say something? Is it a studio pottery mark that someone recognizes?

Thanks,
Kat


The stripes are solid ... there are reflections in the metallic glaze making it look spotty.

 

Looks like 尚泉 "Syousen" or "Shousen."

 

Thank you khl!

My japan to english translator is returning some strange results? Government railway? Cruise line?

 

Just the potter's name.

 

There is a pottery named with those characters, though I can't say whether it made your piece.
