Best Area for Autumn Season Chestnuts in Japan

Chestnuts from the Tanba region in the north of Kyoto are particularly famed for being big and perfectly shaped. These regional autumn season treats are also well-known for their sweetness.

Also, Ibaraki Prefecture, neighboring Tokyo, has the highest chestnut production in Japan! Since it is so close the sprawling Tokyo metropolis, Ibaraki Prefecture welcomes many nearby visitors in the autumn season to enjoy Japanese food including fresh chestnuts.

Autumn Season Chestnut Picking Activities

Like all of Japan’s lovely seasons, fall is full of fun activities that can be enjoyed during this time of year. Among the autumn activities, like tsukimi and maple leaf hunting, gathering chestnuts at a local farm creates great memories with friends and family in the fresh, cool autumn air. Each year, groups venture out into the countryside to find some delicious chestnuts to roast.

Freshly picked chestnuts can last for about 3 to 4 months when kept in a plastic bag and refrigerated. As the chestnuts cool, their starch turns to sweet sugar, making them even more tasty. So, it is recommended to store these autumn season treats for about month.

About Sh旬n

Shun (旬) translates directly into “season”, but strictly speaking in Japan refers to the ten days in which a food (be it a fruit, vegetable, fish or dish) is deemed to be at its tastiest and best period in which it is to be eaten. 季節(kisetsu), which also translates into “season”, refers to six periods within each season (spring, summer, autumn, winter), according to the solar calendar in which a change in the season is deemed to occur – an indication of the Japanese sensitivity to changes in the weather and climate, and its impact on crops and catches of the day. 「A Taste of Sh旬n」aims to bring you the freshest and best harvests, catches and dishes of the day.
