Interstellar Technologies Opens New Tohoku Branch as a Strategic Hub to Strengthen ZERO Rocket Manufacturing

Fukushima (Japan), December 18, 2025 – Interstellar Technologies(“Interstellar”), a leading space infrastructure company, is pleased to announce the establishment of its Tohoku Branch in Minamisoma City, Fukushima Prefecture, in December 2025. This new strategic site will reinforce the production framework for ZERO, Interstellar’s orbital launch vehicle currently under development for its inaugural mission. With this expansion, the Tohoku Branch becomes the company’s fourth manufacturing-capable site, joining the Taiki Headquarters, Tokyo Branch, and Obihiro Branch.

Interstellar, a pioneer in private space transportation in Japan, was the first domestic private company to reach space with its suborbital vehicle, MOMO. The company is currently developing ZERO, an orbital vehicle designed to launch small satellites in response to the global shortage of launch capacity and in alignment with the Japanese government’s goal to enhance domestic launch capabilities.

Fukushima’s coastal Hamadori region, which includes Minamisoma City, has long been recognized for its strong manufacturing base, particularly in the aviation sector. In July 2021 Interstellar became the first space launch vehicle manufacturer to establish a presence in the region utilizing the city’s Industrial Creation Center for its operations. The company’s operations in the region will now be expanded and integrated into the new Tohoku Branch. The facility consolidates and enhances Interstellar’s electrical and mechanical component manufacturing, launch site support systems development, and testing capabilities, and includes office space for up to 30 employees. Several team members, including new local hires, have already begun working at the site.

The opening ceremony for the new branch was held on December 18, 2025, with attendees coming from the local government, financial institutions and other related partners. With the launch of the Tohoku Branch, Interstellar will further contribute to the advancement of the space industry in Fukushima through manufacturing excellence, while accelerating the development of a robust and cost-competitive launch service capable of high-frequency missions.
