The story
Rice farming began here about 2,000 years ago, on flat land by the river fed by clean water from the Kikuchi gorge. From around the 8th century, the plains were divided into a grid of paddies of about 1 ha each, and the Yamato court built Kikuchi Castle, a hilltop fort with rice stores, to guard this rich land. The grid has barely changed in over a thousand years.
Later, canals brought water to the hills. The 11 km Hara-ide canal, with 454 m of tunnels dug by hand, opened terraces in the mountains over 300 years ago and still waters them. The river also carried rice to market: at Takase, bales were rolled down a stone slope onto boats bound for Osaka, and in Yamaga, rice merchants, koji makers and sake brewers lined the streets.
