Aesculus turbinata, common name Japanese horse-chestnut (), is native to Japan but cultivated elsewhere. It is a tree up to tall. Flowers are white to pale yellowish with red spots. Capsules are dark brown, obovoid to pyriform. The seeds were traditionally eaten, after leaching, by the Jōmon people of Japan over about four millennia, until 300 AD. Today the seeds are used in Japanese cuisine to prepare "Tochimochi". Etymology Aesculus was named by Linnaeus, and the name is derived from the Roman name, aesculus, of the durmast oak. Turbinata means ‘conical’, ‘turbinate’, or ‘top-shaped’. References turbinata Endemic flora of Japan Trees of Japan
