A sense of purpose
“When he was over 50, my grandfather (Taikichiro Mori) embarked upon the modernization of Tokyo's Minato Ward with a strong conviction that urban Tokyo must be built upon competitive business infrastructure,” Date said, “and he believed in the role of our family business as a public vessel.”
This philosophy has been passed on from grandfather to father to Date.
“Long-term commitment runs through the family,” said Yoriko Soma, Date’s long-term close friend and president of Conceptasia, a wellness and spa consultancy. The Mori family's approach is to ensure long-term prosperity for any property it develops, Soma said, a stark contrast with the “sell-off-while-developing” transactional attitude commonly observed in Asian real estate developers.
“He was an educator,” Date said of her grandfather, who was originally an economist at Yokohama City University until the age of 55, after which he turned his full attention to real estate development.
"I would go visit him as he sat in a wheelchair, and he would ask me questions that felt like an interview to me,” she said. “My aunt later told me that my grandfather would confide in her that my answers were 'excellent.'"
Ark Hills, the first of the modern “Hills” developments in Tokyo's Minato Ward — combining office and commercial space, residences, a hotel and the acclaimed Suntory Hall concert venue — was inaugurated in 1986 and is a prime example of Taikichiro Mori’s large-scale redevelopment projects. Date, who was a teenager when Ark Hills was completed, etched the before-and-after contrast into her heart — “Before they started construction, there was not much. Then Ark Hills came into shape with sparkles changing the whole landscape.”
Of Taikichiro Mori’s three sons, the younger two inherited the family business while the eldest became an academic. The second son, Minoru Mori, who died in 2012, took the helm of Mori Building, originally a Mori Group company that focused on long-term urban redevelopment consolidating fragmented residential ownership, from his father in 1993. He further expanded urban development with large, multi-decade projects in Minato Ward, exemplified by Roppongi Hills, which was completed in 2003.
The youngest son of Taikichiro Mori, Akira Mori, Date’s father, built his career with Mori Building alongside Minoru Mori and later became CEO of Mori Trust, another Mori Group company. Mori Trust focused on the midterm proprietary development of urban complexes, as well as the development and running of resort and hotel operations throughout Japan. While Mori Building chose to stay close to its roots in Minato Ward, Mori Trust took an expansionary approach, eventually broadening its real estate investment portfolio beyond Japan.
The dissolution from 1999 of the capital relationship between the two businesses — Mori Building and Mori Trust — meant an increased degree of management freedom for both, while the family stayed united in its core principle of long-term commitment to the properties it developed.
According to Date, it is a Mori family tradition to lunch together every week. Originally, her grandfather, father and uncle would huddle over every project at these lunches. Hearing about these conversations from her father as a college student helped Date prepare herself for the family business. When she joined Mori Trust in 1998 at the age of 27, she had graduated with a master’s degree in urban planning from Keio University and had spent several years at a think tank. To this date, Date carries on the family work lunch tradition with her father.
“The Mori family is truly one of a kind, in terms of its contribution to the modern Japanese economy,” said Kengo Kuma, an acclaimed architect known for his involvement in the design of Japan's National Stadium and who frequently collaborates with Mori Trust. He attributes the sustained global competitiveness of urban real estate development in Tokyo, despite a decadeslong relative decline in the country’s economic prowess, largely to the Mori family.
