Noriko, his husband Hirotaka, their seven children and Noriko's sister, Kotomi founded the Kaori Tea Farm near Dark Cloud Village, in the inhospitable Uebe Marshes. The temperature was well suited to these plants, but the soil contained too much moisture. To combat this problem, the family went to great lengths to obtain sand, which they had mixed with the soil. Tea leaves from the Kaori farm had unusual restorative properties. [1]
