Umeboshi (梅干, 'dried ume') are pickled (brined) ume fruits common in Japan. The word umeboshi is often translated into English as 'salted Japanese plums', 'Japanese plums' or 'preserved plums'. Ume (Prunus mume) is a species of fruit-bearing tree in the genus Prunus, which is often called a "plum", but is actually more closely related to the apricot. Pickled ume which are not dried are also called umezuke (梅漬け).

We start making this when you see plums begin to be on the market. While the plums are being pickled, red shiso leaves begin to be on the market. When the rainy season is over, it's time to get the plums out from the jar and sun dry them. Making homemade umeboshi in Japan is always with feeling the change of the seasons.
