Representative image — not a photograph of this location.

Kinchakuda is a loop of flat land inside a hairpin bend of the Koma river, shaped like a drawstring purse, which is what the name means. For most of the year it is a field. For about two weeks around the autumn equinox roughly five million red spider lilies open under the trees along the riverbank in what is generally reckoned the largest natural stand in Japan, and the ground goes an unbroken crimson that photographs badly and looks unreal in person.

The flowers were not planted. Seeds are thought to have washed down the river and lodged in the bend, and the colony spread on its own. The area has a second history: Goguryeo refugees were settled here in 716 and Koma Shrine, a short walk away, is dedicated to their leader — which is why the river, the station and the district all carry the Korean kingdom's name.

Insider Guide

Premium

**The window is about two weeks and it moves.** Hidaka publishes bloom status through September. Arriving a week early gets you a field of stems; a week late gets you brown. **Early bloom and late bloom areas are separate.** The colony is split into sections that open days apart, which extends the season and means one part is usually at its best. The signage marks them. **Go on a weekday morning.** Five million flowers in a small bend of a river draws very large crowds at weekends, and the paths are narrow. **The flowers grow under trees.** Deep shade with red beneath. Bright midday sun blows out the colour; overcast or early light is what the photographs are made in. **Koma Shrine is a ten-minute walk.** Founded for the Goguryeo refugees settled here in 716, and the reason everything in this valley is named after a Korean kingdom. It is quiet even in flower season. **Cosmos in the same field in October.** After the lilies finish, the open part of the bend is planted with cosmos, and admission returns to free.
