Castanopsis cuspidata (Japanese chinquapin; Japanese tsuburajii, 円椎) is a species of Castanopsis native to southern Japan and southern Korea.
It is a medium-sized evergreen tree growing to 20–30 m tall, related to beech and oak. The leaves are 5–9 cm long and 2–4 cm broad, leathery in texture, with an entire or irregularly toothed margin.[2] It grows in woods and ravines, especially near the sea.
The cotyledon of the nut is eaten boiled or roasted.[3]
Its dead wood serves as host to many mushroom types, most notably the shiitake, whose Japanese name (椎茸) is composed of shii (椎, the Castanopsis tree), and take (茸; "mushroom").[4]
