     1763. My deceased father had went to Japan; Lee Chiltan Kwangryo sent a letter on the cultivation of potatoes; at Sasuna on Tsushima island he first attained this; namely, what is called the hyoja-u ("potato of the filial son"). There was a filial son who cultivated it to raise his parents, hence its name.
