Japan Moves to Revise Space Activities Act for Future Growth

The Japanese government plans to amend the Space Activities Act to adapt to evolving space industry needs. This decision follows discussions in recent meetings, including the 118th session of the Committee on National Space Policy on May 21, 2025, where a committee member highlighted the necessity for legislative updates to accommodate emerging space activities.

During the 32nd meeting of the Strategic Headquarters for Space Development on May 30, 2025, Prime Minister Yoshihide Suga emphasized the urgency of these amendments. He stated, “In order to respond swiftly to the development of new forms of space transportation by private companies, we aim to submit the bill to amend the Space Activities Act to the next ordinary session of the Diet.” The government’s commitment to this revision is part of the broader Basic Policy 2025, aiming to stimulate a diverse range of space activities, particularly in private sector transportation.

Key Legislative Timelines and Objectives

The proposed amendments will be introduced at the next ordinary session of the National Diet, scheduled to commence on January 24, 2026. The session is expected to last for 150 days, during which the government intends to present a comprehensive framework for modernizing the Space Activities Act. This legislative effort aims to foster innovation and ensure that Japan remains competitive in the rapidly evolving global space sector.

The Space Activities Act has been instrumental in shaping Japan’s space industry since its enactment in 2016. It governs the launch of artificial satellites and vehicles, providing a foundational legal framework. However, as the space landscape becomes increasingly dynamic, there is a growing recognition that the current legislation may not sufficiently address the complexities of new space ventures, particularly those driven by private companies.

The GT Advisory on the Basic Policy 2025 offers insights into potential amendments to the Space Activities Act. These changes are anticipated to enhance Japan’s space industry capabilities and facilitate the development of innovative transportation solutions.

As the government prepares for these significant legislative changes, stakeholders in the space sector are keenly watching for the proposed amendments. The outcome of this initiative could redefine Japan’s role in the global space economy, fostering growth and collaboration in a field that is becoming ever more critical to national and international interests.

In conclusion, the Japanese government’s proactive approach to revising the Space Activities Act underscores its commitment to advancing the nation’s space ambitions. By aligning legislation with contemporary technological advancements and private sector initiatives, Japan aims to position itself as a leader in the future of space exploration.
