Motoori Norinaga
Haruniwa followed his father and studied the Japanese language from childhood. His father, Norinaga made Haruniwa copy literature of antiquity. Haruniwa wrote down what his father lectured by oral. He contracted an eye disease from August 1791, eventually going blind in 1795. His disease is supposed to be an Uveitis by Adachi Kenichi (足立巻一, a student of Haruniwa.). Haruniwa transferred a Katoku（家督, patria potestas of Japan）of Motoori house to Motoori Ōhira, who was an adoptive son of Motoori Norinaga.
