In this paper we tried to describe and explain the demand structure of larch timber and the distribution channel of larch timber from forest or port to consumer. Larch timber dealt in Shinshu contains Japanese larch (Larix leptolepis) and Dahurian larch (Larix Gmelini). Japanese larch is mainly produced from larch forest in Shinshu, and Dahurian larch is inported from U.S.S.R.. We have prefered the inquiry by questionnarie for primary dealers of larch timber, which have dealt with larch timber in the first stage in the distribution channel, such as timber dealers or sawmillers. Items in the questionnarie are listed in the following : 1) Purchase volume at every purchase method in 1974 2) Selling volume at every area and at every use in 1974 3) Selling volume at every purchaser in 1974 Larch timber is used to some extent in most industries. The largest larch timber consuming industry is building and civil engineering. But the ratio in the total supply depends on the dealt area (Eastern Shinshu, Southern Shinshu, Central and Northen Shinshu), the used area (Shinshu, Tokaido Megalopolis) and the variety of larch (Japanese larch, Dahurian larch). The demand structure of larch timber dealt in Shinshu in 1974 may be sum-marily illustrated as follows : 1) We had used more Dahurian larch than Japanese larch (68.9 % in Central and Northern Shinshu, 65.4% in Eastern Shinshu, 52.7% in Southern Shinshu). 2) Larch timber was mainly used for saw timber (77.9 %), log pile (11.8 %) and utility pole (4.8 %) in Eastern Shinshu, for saw timber (87.0 %), scaffolding pole (4.8%) and log pile (4.5%) in Southern Shinshu, and for saw timber (87.5%) and utility pole (5.2 %) in Central and Nerthern Shinshu. The other uses of larch timber were for pulp chip and mine timber. 3) Larch timber for Shinshu was mainly used for saw timber (97.4 % in Eastern Shinshu, 96.4 % in Southern Shinshu, 91.7 % in Central and Northen Shinshu), but larch timber for Tokaido Megalopolis was mainly used for log pile (51.3 %) and utility pole (17.8 %) in Eastern Shinshu, for scaffolding pole (48.3 %) and log pile (43.0 %) in Southern Shinshu, and for pulp chip (47.9%) and utility pole (42.2%) in Central Shinshu. The demand structure of larch lumber cut dealt in Shinshu in 1974 may be summarily illustrated as follows : 1) We had used more Dahurian larch than Japanese larch (76.8% in Central and Northern Shinshu, 72.8 % in Eastern Shinshu, 66.7 % in Southern Shinshu). 2) Larch lumber cut was mainly used for house building lumber (40.3 % in Easstern Shinshu, 72.0 % in Southern Shinshu, 83.0 % in Central and Northern Shinshu) and civil engineering rough lumber (48.8 % in Eastern Shinshu, 16.0 % in Southern Shinshu, 15. 0 % in Central and Northern Shinshu). The other use of larch timber was for boxes and crating. 3) Larch timber cut for Shinshu was mainly used for house buildig lumber (78.0 % in Eastern Shinshu, 87.0 % in Southern Shinshu, 83.5 % in Central and Northern Shinshu), but larch lumber cut for Tokaido Megalopolis was mainly used for civil engineering rough lumber (77.9 % in Eastern Shinshu, 55.4 % in Southern Shinshu, 70.3 % in Central and Nothern Shinshu). The distribution structure for larch timber dealt in Shinshu in 1974 may be summarily illustrated as follows : 1) In distribution channel for saw timber and house building lumber, saw millers played a significant role. 2) Wholesalers took a important position in distribution channel for log pile and civil engineering rough lumber.
