The mark is reading from right to left: Hizen 肥前 Arita 有田 Yamaguchi 山口 Zo 造 = Made by Yamaguchi in (the town of) Arita (in the former) Hizen province, see picture below.
This is an Arita Imari vase - not Kutani - made in the style of Hichozan, Fukagawa and Zoshuntei from about the same period (Meiji).
The vase is made about 1880-1900, probably by Yamaguchi Kogetsu (1844-1904), who was one of the most famous Japanese woodblock-prints painters. Occasionally he seemed to paint ceramics as well on demand (vases and plates), there are a few more marks with his name found on ceramics.
The characters on the neck read:
Migi 右 Go 五 (five 5), so it was the right vase of a pair. No idea what the 5 means in this case.
