Aesculus turbinata
Species of tree
Aesculus turbinata, common name Japanese horse-chestnut (Tochinoki or Tochi (トチノキ(栃の木) or トチ(栃、橡))), is native to Japan but cultivated elsewhere. It is a tree up to 30 m (98 ft) tall. Flowers are white to pale yellowish with red spots. Capsules are dark brown, obovoid to pyriform.[4][1] The seeds were traditionally eaten, after leaching, by the Jōmon people of Japan over about four millennia, until 300 AD.[5] Today the seeds are used in Japanese cuisine to prepare "Tochimochi".
