 note = {The forest-areas called "Okureki-yama" in Ina-gun of Shinsyu (now a part of Nagano prefecture) was under the direct control of the Tokugawa Shogunate throughout the early modern Japan (1600-1868;the Edo period).After the fifth large scale logging of Okureki-yama, during 1760-1764, the village officials of Ohkawara-village offered a document about trees on Okureki-yama in 1766. In the document they reported that bigger Hinoki cypress (Chamaecyparis obtusa) and Japanese arbor vitae ( Thuja standishii) trees were lost from the forest due to rock slides, floods and stand-decaying. The finance ministry (Kanjo bugyo-sho) of the Tokugawa shogunate had some doubts about it, and investigated the village officials and the state of the forest. Nowadays the sites investigated are called Arakawa dai-hokaichi (Arakawa gigantic Rock slide) and Hirokawara (wide dry river bed formed on the waste-filled valley). Two illustration maps of these sites in 1763 and 1769 have remained in the storehouse of the one-time chief official of the village. This paper deals with geographic features of these sites shown by the illustration maps and related one.},
