Japanese Chestnut🌳
Castanea crenata
クリ
A deciduous tall tree native to Japan and the Korean Peninsula. The spiny bur-enclosed nuts, which ripen in autumn, have been eaten since the Jomon period. The male catkins appear in early summer as white spike-like clusters with a distinctive odor. It is one of the most representative edible trees of the satoyama landscape.
