What is "Mansion Mirai Value Research Institute"?

Established in 2019 as the first comprehensive research institute by a condominium management company. It analyzes various problems existing in condominiums, which have become a "social infrastructure" in Japan, such as the shortage of board members due to the aging of residents and the shortage of repair reserve funds due to rising construction costs caused by the aging of buildings and soaring labor costs. It disseminates research reports to contribute to the creation of new value for condominiums.
