Interstellar Technologies Completes Series F Round With 20.1 Billion JPY ( 129.7 Million USD)

Tokyo (Japan), January 15, 2026 – Interstellar Technologies (“Interstellar”), a leading space infrastructure company, announces the completion of 20.1 billion JPY (129.7 million USD¹) in Series F funding through a third-party allotment of new shares. The round was completed with the investments from SBI Group, Nomura Real Estate Development, B Dash Venture, SMBC Edge, and existing shareholders, in addition to the previously announced investors.

Interstellar’s Series F round represents one of the largest fundraising to date by a privately held space startup in Japan², bringing Interstellar’s cumulative funding to 44.6 billion JPY (287.7 million USD). The round, led by Woven by Toyota, raised 14.8 billion JPY (95.5 million USD) through a third-party allotment of preferred shares in an up-round.

In addition, the company secured 5.3 billion JPY (34.2 million USD) in debt financing from financial institutions, including 1.8 billion JPY (11.6 million USD) in loan facilities with stock acquisition rights provided by the Japan Finance Corporation. Alongside the fundraising, secondary transactions with existing shareholders were also conducted to optimize the company’s capital structure. Nomura Securities provided advisory support in this series, including the introduction of several potential investors, some of which resulted in fundraising.

As a leading private space transportation company in Japan, Interstellar is working to realize the country’s first vertically integrated business combining launch vehicle services and satellite communications. In its launch vehicle business, the development of orbital launch vehicle ZERO has been selected for Phase 3 of the Ministry of Education, Culture, Sports, Science and Technology’s (MEXT) Small Business Innovation Research (SBIR) program, with Interstellar being chosen as one of only three companies to successfully pass the latest stage-gate review.

For ZERO’s first launch, seven domestic and international satellites have already been confirmed as customers, with launch contracts signed with a total of eight companies, organizations, and universities, including one company conducting a demonstration of a satellite separation system. In parallel, Interstellar has established a manufacturing-focused business alliance with Toyota Motor Corporation and Woven by Toyota is advancing efforts to establish a robust production system, an area that has traditionally been challenging to develop within Japan’s relatively small space industry. Through these initiatives, Interstellar aims to deliver highly competitive space transportation services from Japan, capable of supporting high-frequency launches for customers both domestically and internationally.

On the satellite business side, Interstellar is focusing on communications satellites, which typically require frequent launches and represent an area where a vertically integrated company can maximize its competitive advantage by utilizing its own launch vehicle. Research and development for this project is being advanced through commissioned projects from the Ministry of Internal Affairs and Communications, as well as initiatives such as the Space Strategy Fund implemented by the Japan Aerospace Exploration Agency (JAXA).

The funds raised in this round will be used primarily for the development of ZERO’s first launch vehicle, strengthening the manufacturing system toward future commercialization, and the research and development of satellites, thereby driving further expansion of both businesses.

Comments from new investors

“Following our participation in the previous round, we have made an additional investment in the current round. Space transportation represents a critical infrastructure underpinning the industrial foundation of the rapidly expanding global space market; however, the number of operators in Japan remains limited. In this context, Interstellar Technologies　has established itself as a leading domestic player, distinguished by its robust technological capabilities and strong execution track record, and we expect it to further enhance its presence in the global market going forward. Together with newly participating investors who provide strong strategic support, the SBI Group will continue to fully support Interstellar’s business growth and the ongoing strengthening of its organizational structure.” – Hiroyuki Ono, General Manager, SBI Investment (SBI Group)

“The global space industry is experiencing rapid growth, and within it, the rocket business plays a core role in the space industry. Interstellar Technologies has, from an early stage, taken a global perspective and steadily built a strong business foundation by combining technological development with commercialization efforts and strategic partnerships. We look forward to supporting Interstellar Technologies as it continues to scale further and achieves success in the global market.” – Hiroyuki Watanabe, CEO, B Dash Ventures.

“Interstellar Technologies, guided by its mission of “Empowering Society Through Space Infrastructure,” is a core startup in Japan’s space industry that is pioneering private-sector–led access to space. Through this investment, we will go beyond providing financial capital and deliver integrated support in business development and talent acquisition to accelerate the company’s growth. Together with Interstellar Technologies, we will take on the challenge of building a new space industry in the strategically and nationally important field of space transportation.” – Spokesperson, SMBC Edge.
