In 1911, Mizoguchi's parents, too poor to continue paying for their son's primary school training, sent him to stay with an uncle in Morioka, in northern Japan, for a year - a period that saw the onset of crippling rheumatoid arthritis that was to afflict him during adolescence and leave him with a lop-sided walking gait for the rest of his life. The year 1912, back with his parents, was spent almost entirely in bed. In 1913 Mizoguchi's sister Suzu secured him work as an apprentice, designing patterns for kimonos and yukatas. In 1915 his mother died, and Suzu brought her younger brothers into her own house and looked after them. In 1916 he enrolled for a course at the Aoibashi Yoga Kenkyuko art school in Tokyo, which taught Western painting techniques. At this time too he pursued a new interest in opera, particularly at the Royal Theatre at Akasaka where he began, in due course, to help the set decorators.
