Hortica said: It looks like a variety of an Asian persimmon, but I may be mistaken, as I only see a few varieties of the American species.
Is it astringent when firm ripe? Does it have seeds? Can you post a pic of the fruit sliced across and one sliced from top to bottom?

Hortica said: "a hint of astringency " would be normal for a non-astringent variety; true astringent varieties would be inedible when firm, and only loose the pucker power as they get very soft.
