This is Japanese Satsuma ware, I believe late Meiji period (1890-1910)
The mark reads: Satsuma 薩广 Yaki 焼 - Tomo 伴 = Satsuma ware - Tomo (is a family name).
Satsuma is normally written as 薩摩, but in this case a shortened form 广 of the 2nd Kanji is used.
Tomo is the native Japanese translation of 伴, in Sino Japanese reading it might be Han or Ban, also family names.
Perhaps that someone else knows more.
Anyway, I have no information about the artist.
I've found marks without the Satsuma Yaki part, see my picture.
