I agree it looks like go, despite the stones not all being on the intersections of the lines. Also, the board has only 17x17 lines. I believe that by the Edo period it was standardized to 19x19; earlier boards had more variation. It's a plausible board position, could have been taken from depictions in Chinese or Japanese art. Black seems to have a solid lead.
A Chinese Go (Yi) Board with a 17 x 17 grid was found in a tomb (apparently, improvised so the tomb guards could play) dated to Eastern Han (20 - 220 CE or so) while the earliest (Chinese) 19 x 19 board was a ceramic board dated to the Sui Dynasty (581 - 618 CE)
Interestingly, the 17 x 17 board is still played in Tibet. Alas, nothing else in the picture looks Tibetan, but wouldn't that be Something Different!
I suspect a Classical Chinese Faction of Han Dynasty . . .
