Insider tip — Nagomi at Mori no Seseragi serves Kuki City on the Kanto plain north of Tokyo where the Sakai River preserves a narrow riparian forest corridor through the heavily urbanized landscape of central Saitama. Kuki City was historically the market town for the silk-producing communities of the northern Kanto uplands, and the city station district preserves the commercial architecture of the Meiji and Taisho silk-trading era when Saitama raw silk was transported to Yokohama for export aboard the Tobu railway that made Kuki a prosperous entrepot on the edge of the metropolitan region.
