Former astronaut Naoko Yamazaki shares her vision for bilateral space cooperation and spaceports in Japan

The United States and Japan share a long history of collaboration in space, working together on projects such as the International Space Station (ISS) and the Artemis program, which aims to return astronauts to the moon by 2024 and can also be seen as a preparatory stage for human missions to Mars.

Cooperation between the two countries in the space industry is growing stronger and represents a great pathway for innovation in the bilateral relationship. A significant player in the space travel industry in Japan is the Space Port Japan Association (SPJ), which was established in 2018 and is attracting considerable attention on both sides of the Pacific.

SPJ co-founder and Representative Director Naoko Yamazaki joined members of the American Chamber of Commerce in Japan (ACCJ) on April 21 for an hour-long online discussion organized by the Chubu Aerospace and Manufacturing Committee.

Licensed to Fly

The accomplishments of Yamazaki, who participated as a panelist at the ACCJ Women in Business Summit in 2014, are impressive. Currently she is a member of the Committee on National Space Policy at Japanese Prime Minister Fumio Kishida’s Cabinet Office. And as a former astronaut with the Japan Aerospace Exploration Agency (JAXA), she became the second Japanese women to fly into space when she took part in an assembly and resupply mission to the ISS in 2010 aboard the space shuttle Discovery. She retired from JAXA in 2011.

Besides appearing in the media to promote the SPJ, Yamazaki occasionally meets with government officials in both the United States and Japan. For example, US Ambassador to Japan Rahm Emanuel greeted her and space startup leaders at the US Embassy, Tokyo, in February to discuss bilateral collaboration on the space front.

Direct Connections

During the April 21 webinar, ACCJ members learned that direct cooperation began with the signing of the 1969 US–Japan Space Agreement and has since blossomed into a relationship involving many US-made products. While a young organization, the SPJ has already established relationships with four regional governments interested in hosting spaceports. The projects include:

• HOSPO (Taiki, Hokkaido Prefecture)
• Spaceport Kii (Kushimoto, Wakayama Prefecture)
• Shimojishima Spaceport (Okinawa Prefecture)
• Spaceport Oita (Beppu, Oita Prefecture)

Other cities in Japan are also interested in such an investment in point-to-point suborbital space transportation hubs.

Besides sending future passengers to other planets, spaceports in Japan could become a launchpad from which to transport time-sensitive food and cargo to other locations on Earth. For example, Yamazaki pointed out, entrepreneur and investor Elon Musk proposed in 2017 a plan to use his SpaceX rockets to fly passengers from New York to Shanghai in just 39 minutes.

Supporting STEM

Yamazaki is recognized as a space policy expert not only in Japan but also in the United States. She was recently invited by the University of Pennsylvania (Penn) as a visiting fellow at the Perry World House, a center for scholarly inquiry, teaching, research, international exchange, policy engagement, and public outreach on pressing global issues. She is lending her expertise to Penn so that its students can develop and advance innovative policy proposals, and hopes to see more Japanese students benefit from the experience of studying abroad.

Finally, Yamazaki spoke about her involvement in the Japanese Rocket Society, where she chairs the Sorajo Committee, whose name means women in aerospace. She is a staunch advocate of inclusivity and gender equality in the Japanese aerospace industry—a goal very much aligned with the beliefs of the ACCJ and its member companies. Science, technology, engineering, and mathematics—or STEM—is a growing area of passion for this former astronaut, and we hope to see her and other members of the SPJ at future ACCJ events.
