Apparently my in-laws have a Japanese plum tree in their yard. I never knew this, but today it had the fruit on it. I don't think this is a true Ume tree, but my FIL said it was called Japanese plum. He described the taste as between an orange and a plum. I tried it, but it was pretty sour. He said someone nearby comes and picks them and makes a nice jelly out of them.
