Will Accommodate Research in Diverse Business Domains, Including Life Sciences, Semiconductors, Energy, Food Products, Chemistry, and Space Construction Started on MITSUI LINK-Lab TOYOCHO 1 (tentative name) Scheduled for Completion in Summer 2026

Tokyo, Japan, April 10, 2025 - Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, announced today that it began construction on MITSUI LINK-Lab TOYOCHO 1 (tentative name) on April 10, 2025 as an urban proximity-type rental lab and office facility in the new asset class Mitsui Lab & Office business. Construction is scheduled to be completed in summer 2026.

As an “industry developer,” Mitsu Fudosan works to create new industry. In the life sciences domain in particular, as the Mitsui Lab & Office business, it is collaborating with Life Science Innovation Network Japan Inc. (LINK-J) in “community building,” and by “developing sites” it has accelerated ecosystem construction linked to creating and fostering new industry thorough innovation.

MITSUI LINK-Lab TOYOCHO 1 (tentative name), on which construction is beginning, will offer comprehensive support for R&D needs in diverse domains, not just the life sciences. By flexibly accommodating the needs of each company, diverse sites will be developed that will lead to the creation and fostering of new industry and promote the aggregation and collaboration of diverse players.

Characteristics of MITSUI LINK-Lab TOYOCHO 1 (tentative name)

The MITSUI LINK-Lab series thus far has been developed targeting the life sciences, but for this project, the characteristics of an industrial area will be utilized so that it can be used by customers in a broader range of business domains. Specifically, the building is being designed to allow large-scale equipment to be easily brought in and set up. In addition, it will accommodate large-capacity electricity supply and efficient duct routes to comprehensively support the R&D needs of not only the life sciences but also diverse business domains that include semiconductors, energy, food products, chemistry, and space.

MITSUI LINK-Lab TOYOCHO 1 (tentative name) is located a 10-minute walk from Toyocho Station on the Tokyo Metro Tozai Line. It is around a 10-minute train ride to the Otemachi area, offering smooth access to the city center. In addition, taking advantage of its location facing the Shiohama Canal, the design will feature a waterfront terrace and include a side entrance accessible from the canal side, creating a sense of openness.

In addition, in common spaces, there will be a LINK-J lounge and meeting rooms to promote internal and external communication, and the facility will function as a place for social interactions and as a third place. Facilities such as a café and a convenience store will also be included to create a comfortable research environment.

About Life Science Innovation Network Japan Inc. (LINK-J)
LINK-J is a general incorporated association established in March 2016 by Mitsui Fudosan and volunteers from academia and industry. Based in the Nihonbashi, Tokyo area, which has a cluster of pharmaceutical companies, LINK-J’s purpose is to promote open innovation in life sciences through industry-government-academia partnerships and support the creation of new industry. It will promote internal and external personal interactions and technology exchanges beyond any specific field in the life science domain, which is a composite of all the sciences, including medicine, physical science, engineering, ICT, artificial intelligence, and other new technologies.

Sustainability in the Mitsui Fudosan Group
Based on the meaning of its “& mark,” “to generate new value with society through cooperation, coexistence and co-creation, we forge ahead, innovating,” the Mitsui Fudosan Group views the “creation of social value” and the “creation of economic value” as two wheels of a cart. Accordingly, we believe that the creation of social value leads to the creation of economic value, and that this economic value then creates even greater social value.
Moreover, we identified six Group Materiality priority issues when formulating our new management philosophy in April 2024. These Group Materiality priority issues are (1) Contribute to industrial competitiveness, (2) Coexist with the environment, (3) Health and Vitality, (4) Safety and security, (5) Diversity and inclusion, and (6) Compliance and governance. The Mitsui Fudosan Group will work to address each of the materialities through its core business activities and contribute to the promotion of sustainability.
