Mitsui Fudosan said on July 31 that it had completed its Mitsui Link Lab Toyocho 1 rental lab-and-office facility and started development of a second site in the same Tokyo district, tentatively named Mitsui Link Lab Toyocho 2, as the property developer expands its life sciences footprint in the Kanto region.
The two Toyocho properties will bring the Mitsui Link Lab series to 10 locations in the Kanto area, including planned sites. The series already has locations in areas including Shinkiba in Tokyo, Kashiwanoha in Chiba and Yokohama in Kanagawa.
Toyocho 1 is the first project in the Mitsui Link Lab series to be located in an industrial-exclusive zone, a Japanese land-use category generally designated for factory and industrial activities.
Mitsui Fudosan has positioned itself as an “industrial developer” focused on creating new industries. In life sciences, it has worked with LINK-J, a general incorporated association that supports networking in the sector, combining community-building efforts with the development of physical lab and office space.
The company said it aims to broaden the life sciences cluster spanning Shinkiba and Toyocho. Mitsui Fudosan has until now mainly concentrated its lab-and-office accumulation in Shinkiba, and the move into Toyocho extends that ecosystem into a new area.
Japan has been seeking to strengthen its domestic life sciences and biotechnology base through industry, academic and medical collaboration, particularly in urban clusters that can combine research functions with startup and corporate activity. In Tokyo, waterfront and eastern districts including Shinkiba and Toyocho have industrial land and transport access that can accommodate laboratory uses.
