The mark is upside down and reads:
Hizen 肥前 Arita 有田 Yaki 焼 Teizan 貞山 Saku 作
= Hizen Arita ware Work by Teizan.
Teizan Gama is a prestigious Arita ware pottery located in Yamauchi-machi, Takeo. Dedicated to pottery as a designated kiln for preserving one of the few craftsmanship techniques before the war. It is still a pottery that makes many products by hand.
These looks like old marks, but they are not. Estimated to be from the early Showa, but might even be later (1940's - 1950's).
