Abstract

“Yato” is a landscape unit that is formed by the first order stream, or at least by very upstream part of a river.“Yato” landscape is a mosaic of fountain, stream, agriculture field, woods on lope, and upper land. Ecologically rich “Yato” is one of the most important element in the concept of Ecocity.This article analyses the distribution and ecosystems of “Yatos” in Yokohama City as a fundamental information or the future of Ecocity Yokohama.“Yato” landscape was created during the Jomon transgression. After the medieval ages, valley bottoms were developed for agricultural purposes and there developed the semi-natural ecosystems. Old topographical maps reveal that there were 3, 751 “Yatos” with the first order stream in the city area, and the “Yatos” were located all over the area. Many hamlets were named after the “Yato”. Yokohama was the city of “Yato”. Recent urban development has drastically changed the landuse and topography of “Yatos”. Today there are 2, 467 “Yatos” remain, and only 944 “Yatos” keep natural and semi-natural landuse.
