 Some of them were "uchi-deshi", live-in students.Ueshiba placed many demands on his "uchi-deshi", expecting them to attend him at all times, act as training partners (even in the middle of the night), arrange his travel plans, massage and bathe him, and assist with household chores.There were roughly four generations of students, comprising the pre-war students (training 1921–1935), students who trained during the Second World War (c.1936–1945), the post-war students in Iwama (c.1946–1955) and the students who trained with Ueshiba during his final years (c.1956–c.1969).
