As I wrote before at your earlier post, the mark reads: Kutani 九谷 Itsuzan 逸山 Ga 画 (Kutani painted by Itsuzan), mark of Hatta Itsuzan.
In the mean time I found a little information about this Hatta Itsuzan on a Japanese website.
Hatta Itsuzan was a pottery painter from the Kutani region in the Meiji Period. He learned from Sasada Yuzan, who was a ceramics worker active during the early Meiji era and the middle term. Later, Itsuzan was the teacher of Ishino Ryuzan. So this mark of yours might date something like 1880-1910.
Itsuzan was a painter for overseas pottery merchants such as Marunaka Magoji, Matsubara, the Watano Kichiji studio and even for Kinkozan (Satsuma). I found an Itsuzan mark on the body of a vase with on the bottom an impressed Kinkozan mark.
Date of birth and death are unknown.
