KOSHU Chestnut
Origin: Yamanashi Prefecture
From the Edo period to the Meiji era, chestnuts were known as one of the “Koshu Eight Delicacies” (Kōshū Hatchinka), a group of Yamanashi’s most renowned fruits. (The others were peaches, grapes, persimmons, pears, apples, plums, and loquats.) The term “Eight Delicacies” signifies the finest quality fruits, which were famous as offerings to the shogunate and as luxury gifts.
As a timber, chestnut wood contains a high amount of tannin, giving it excellent insect-repellent, anti-decay, and highly durable properties. It is also prized for its beautiful grain and stability after drying, making it a first-class material. Known as a foundation wood that can last for a hundred years, it was once commonly used as railroad sleepers, where absolute stability was required.
Meaning: Satisfaction, sincerity, gratitude
