It's until the beginning of December that the persimmon leaf sushi which turned red can be enjoyed from November. Time besides that, persimmon leaf sushi using a new leaf can be enjoyed from corned leaf and May to October until December-May.
Persimmon leaf sushi from Mr. vicinity in a mountain can be bought at a online shop, unfortunately it's said that this year's persimmon leaf sushi is sold out already.
It itself is each place by Nara-shi, and it's said that leaf sushi of a free persimmon is also sold at the unpleasant station, so when dropping in at Nara, how about looking for "persimmon leaf sushi"?
