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".

Aesculus was named by Linnaeus, and the name is derived from the Roman name, aesculus, of the durmast oak.^[6]

Turbinata means ‘conical’, ‘turbinate’, or ‘top-shaped’.^[6]
