Thatched roofs in Japan, known as kayabuki, primarily use kaya (a general term for thatch) harvested from Miscanthus grass, specifically Japanese pampas grass susuki (Miscanthus sinensis) and kariyasu. Other materials include reed (yoshi), cogongrass (chigaya), and rice straw. These materials are harvested, dried, and bundled to create a durable, insulating 30–40 year roof.
