Akita
cedar was one of the crucial revenue sources of the Satake Clan, in what is
now Akita Prefecture, but the resource became depleted over a hundred years
from the early seventeenth century. This compelled the clan to carry out various
reforms. Among them, "Banyamaguri-seido" is especially famous. It was
an original system of the clan to cut down cedar in specific areas in a thirty
year rotation. The forests conserved by the clan were taken over by the newly
established government after the Meiji Restoration and were included in national
forests. The total area amounted to 95,000 ha.
