>hachiya vs. fuyu
There is a persimmon tree on a street where I take occasional walks. There is still plenty of ripe fruit remaining on the reachable branches.
???
1) People in this neighborhood wouldn't think of taking someone else's fruit, even when it belongs to the city, or
2) Many people must still be oblivious to this one of the tastiest fruits on this planet, or
3) People are very knowledgeable indeed - they know this is hachiya, on the left, a pointy shaped, soft-ripening persimmon, which can be extremely bitter when not completely ripe.
...as opposed to flat-shaped fuyu, on the right, which ripens firm, and almost always tasty.
This versatile, universally liked sweet fruit is also my favorite. Some people even call it Sharon fruit!
