Production. The raw materials are grown by the Tsujiki tea garden, represented by Tsujiki Yoshiharu, a fifth-generation grower working his family's own tea garden. According to Royal Blue Tea, the Tsujiki garden lies along the Uji River, where morning mist rises, with well-drained sandy soil and minimal frost.^[4]

The wooden box is made from domestic Aizu paulownia, domestic cherry wood, and domestic ebony, crafted by artisan Hiroki Tahara of Kyoto Kiribako Kogei in Yamashina, Kyoto.
