Tokyo, Japan, October 10, 2025 - Mitsui Fudosan Co., Ltd., a leading global real estate company headquartered in Tokyo, and cross U, a general incorporated association also based in Tokyo, announced today that they will hold NIHONBASHI SPACE WEEK 2025 from Tuesday, October 28 to Friday, October 31, 2025 in the Nihonbashi area. NIHONBASHI SPACE WEEK is Asia’s largest space business event where players in the space business from Japan and overseas will gather.

This year’s event will be held for the fifth time. It has expanded in scale to become Asia’s largest space business event, including participation by more than 100 companies and organizations from Japan and overseas, and over 30 space-related events held during the event period. At the same time, the event is further accelerating international co-creation, including more than 20 organizations attending from Europe, North America, and Asia, representing over 10 countries. Through this event, the organizers seek to foster new co-creation in the space business by creating opportunities for event participants to gain exposure to the latest space business trends and interact with key players in industry, government, and academia, with the goal of energizing the global space industry from Nihonbashi.

According to the latest report released in 2024 by the World Economic Forum, the market size of the space business is forecast to grow to $1,800.0 billion (approx. ¥280 trillion) by 2035. In Japan, support programs including the Space Strategy Fund*, which provides funding of around ¥1 trillion over 10 years, have begun full-scale operation. Market entry by players ranging from startups to major non-space companies, and small and medium-sized enterprises from different business sectors is becoming an increasingly realistic option. Furthermore, Japan’s space industry continues to grow rapidly, driven by factors such as accelerating partnerships between major non-space companies and space startups.

Nihonbashi is strengthening its presence as a hub that brings together space-related players in the public and private sectors. Notably, in January 2025, the space business site in Nihonbashi operated by cross U and Mitsui Fudosan was expanded, and JAXA began operations related to the Space Strategy Fund. Going forward, cross U and Mitsui Fudosan will continue to promote public-private collaboration from their base in Nihonbashi, contributing to the further development of space-related industries.

* About the Space Strategy Fund (excerpted from Cabinet Office materials)
The Space Strategy Fund (with up to ¥1 trillion in funding), a 10-year fund for JAXA, was established to support private-sector companies, universities, and other entities over several fiscal years in their efforts to develop, demonstrate, and commercialize advanced space technology.

■Mitsui Fudosan’s Initiatives for Space-Related Industry Creation

Mitsui Fudosan has been promoting the Nihonbashi Revitalization Plan since the second half of the 1990s in a collaboration between the public and private sectors and the local community. A key strategy of the plan is “industry creation,” which supports the development of industries through neighborhood creation. Since 2019, Mitsui Fudosan has been working on space industry creation. In 2023, cross u was founded by Mitsui Fudosan and other parties involved in the space business, and it has since been advancing its activities.

■About cross u

https://www.crossu.org/
A space business co-creation platform founded in 2023 by Mitsui Fudosan and other parties involved in the space business whose goal is to invigorate space-related businesses. In addition to the business matching know-how fostered by Mitsui Fudosan through providing places/locations and creating opportunities, cross U offers a support structure combining industry, government, and academia that encourages relationships, connection, and development that transcend organizational boundaries among players in diverse industries, making Nihonbashi a base for invigorating the global space business. It also seeks to apply space-related technologies to solve the challenges of our planet to achieve a sustainable society.

■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.
