This is a mark of "Kinkozan Zo", the Japanese Kinkozan studio in Kyoto, which was active during the late 19th-early 20th century.
I've provided a link to the same mark, with an added "Made in Japan", which would date that piece to 1920 or later, and yours probably not far behind. If you use the forum's search feature to query the Kinkozan name, you'll get a better appreciation of this historic studio.
