Mitsui Fudosan Residential Wellness Co., Ltd.
Mitsui Fudosan Residential Co., Ltd., a leading housing company headquartered in Tokyo, established a senior residence business division in April 2017, and has been considering products and services that provide quality housing and abundant lifestyle to senior citizens.
The company has decided on the brand concept of the senior residence business and an outline of product plans, and will be progressing multiple projects in Tokyo and surrounding areas.
The population of senior citizens and number of households comprising only senior citizens is increasing sharply amid trends such as Japan’s low birth rate and a shift toward smaller households in recent years. The average life expectancy in 2050 is expected to be 84.0 for men and 90.4 for women1, creating a new life stage for the elderly.

The Mitsui Fudosan Group has named a new category of housing suitable for this new life stage “serviced senior residences.” They will allow healthy senior citizens to live full lives that honor their tastes and preferences. In this context, the Group has developed PARK WELLSTATE as a new brand that assumes quality products and services for seniors.
The Group has started development of three properties in Tokyo and Chiba, and plans to accelerate development in major cities, mainly in Tokyo and three neighboring prefectures.
