Life in the dormitory is led by a unit that consists of bed rooms, a common room and service area so as to “Group (Gun).” 30-40 students from the first year to the fifth year belong to each Group. Members of each Group determine their own “rules of life” led by a leader of the Group and strive to carry out the communal life they think the best; they improve each member’s self-discipline and sociality, and demonstrate that in rather liberal atmosphere according to those rules. Chiefs of administrative staff of the dormitory, all of group leaders, and members of the relevant faculty give instructions and discuss problems in daily life at the Group Leaders’ meeting held every Tuesday.
