the clan government. This species grows in Kyushu and the 

 southern part of Honshu. It really forms pure forest but 

 rather is found mixed with other species of Quercus occupying 

 vast areas. It being shade bearing in nature, well grows 

 under the shelter-wood and the forests may be renewed either 

 through natural regeneration or by means of planting. 



Principal varieties of deciduous broad-leaved trees are 

 Kunugi {Quercus serraia Tkunb.\ Konara [Quercus glandulifera 

 Bl.\ and Shide [Car phi us laxi flora /]/.). 



Kunugi [Quercus serrata Thunb. ). This is used as fuel of a 

 superior quality and the material for making charcoal. It ranks 

 next to the other varieties of Quercus in the quality. Partly 

 owing to the easiness of forming the forests and partly to the 

 fitness for intensive working under the short rotation, this 

 species is largely planted in the private forests. In these daws, 

 with an exception of the northern half of Honshu and 

 Hokkaido, these forests are extensively grown in Shikoku, 

 Kyushu, and the southern part of Honshu. The bark of this 

 species contains tannin and is used for dyeing and in the 

 tannery industry while there is a large demand of this tree as 

 the wood upon which " Shiitake " (a kind of mushrooms) is

Konara [Quercus glandulifera />/.). As the firewood and 

 charcoal, the demand of this species is quite extensive. This 

 is the principal tree in the forests of natural growth comprising 

 various species of trees around mounds and on hills in Honshu. 

 The area covered by these forests is quite extensive, reaching 

 Hokkaido passing through the northern part of I [onshu. Like 

 the Quercus serrata Thunb. % this species having light demand-
