Castanopsis sieboldii is a species of flowering plant in the family Fagaceae.[2][3] This evergreen tree is sometime referred to by the common names Itajii chinkapin or Itajii. It is native to Japan, including the Ryukyu Islands, and Korea.[2][4][5]
This is a climax species that is commonly found in the Japanese temperate rainforest.[6] Specimens are also present within the forest area of the Tokyo Imperial Palace.
Castanopsis sieboldii was once thought to be a subspecies of the similar Castanopsis cuspidata.
Plants and animals associated with this tree include:
- Mitrastemon yamamotoi, a non-photosynthetic plant that parasitizes Castanopsis sieboldii.
- Aspidistra elatior, the cast-iron plant, grows in the understorey.
- Acrocercops mantica, Chrysocercops castanopsidis, and Lymantria albescens[7] larvae of these Asian moths likely mine the leaves.
- Amantis nawai, a small praying mantis species native to Eastern Asia is known to live around C. sieboldii where it eats insects.
- Okinawa rail, a Japanese bird, lives among these trees.
