On-take in central Honshu (.by the courtesy of Mr. H. Chimura).. -ft There are several localities where plantations have been established in Japan. Notable plantations can be found at: (6) Asakawa Experiment Forest, Tokyo, Honshu. One plantation was established in 1930, and measured in 1960. At that time, the average diameter was 14 cm (max. 22 cm) and the average height was 10 m (max. 16 m). Another plantation of 1935 origin had an average diameter of 12 cm (max. 20 cm) and height of 12 m (max. 16 m) . (7) Tokyo University Forest in Chiba, in east-central Honshu, where the plantation was established in 1930 and measured in 1960. Vlhen measured it had an average diameter of cm and an average height of m. (8) Kemuriyama, Iwate Prefecture, northern Honshu, where one of the plantations that was planted in 1930 and measured in 1956 showed an.
