In this study, I drafted a super-long-term repair plan. As a result, I made it clear that: (1)Super-long-term repair plans cannot accurately calculate future payment amount for repair reserve. However, it is possible to predict when there will be a significant shortage of repair reserve fund. (2)A factor that will increase future repair costs is the life environment improvement work that is carried out in conjunction with extensive renovations. (3)For ultra-aged condominiums, it is important to announce in advance that the payment amount for repair reserve will increase by using super-long-term repair plans.
