This mark is from the Eisei-sha 永世舎 pottery.
Eisei-sha was established in 1877 in Himeji (Himezi) in the Hyōgo Prefecture by Tatsumasa Matsumura (1838-1915), born in Hizen, Arita, Saga Prefecture.
Eisei-sha is a pottery located in former Okurae-cho, Himeji, Hyogo Prefecture. It was active for about 6 years in the Meiji Period from 1877 till 1883. The director was Shibata Zenpei (also named Shibata Yoshihira), a potter of the Oyama kiln. Eisei-sha made mainly appreciated trade items.
The logo is the character 永 (= Ei) in a diamond (rhombus).
