Japanese startup Letara raises $16M to expand hybrid rocket systems
Original: Japanese space tech startup Letara expands beyond satellite thrusters with $16M
Why This Matters
Letara's expansion reflects Japan's broader push to build a globally competitive domestic aerospace and defense sector.
Sapporo-based space tech startup Letara has secured ¥2.6 billion (~$16M) in new funding to expand from satellite thrusters into large hybrid rocket systems for space, defense, and security markets. The round was co-led by Headline Asia, JIC Venture Growth Investment, and Incubate Fund.
Letara, a Sapporo-based startup developing hybrid propulsion systems for spacecraft, has raised ¥2.6 billion (~$16 million) in a new funding round. The round was co-led by Headline Asia, JIC Venture Growth Investment, and Incubate Fund, with strategic participation from NES Corporation, Toyoda Gosei (a Toyota Group supplier), and Frontier Innovations, a fund backed by JAXA, Japan's space agency. Previously focused on hybrid thrusters for small satellites, Letara now plans to develop large rocket systems targeting space, defense, and security markets. Co-CEO Shota Hirai stated: 'We plan to explore a much wider set of use cases across both the space domain and the defense and security domain.' Letara's core technology uses a hybrid rocket design that keeps solid fuel — made from inexpensive materials like plastic and rubber — separate from a liquid oxidizer. A proprietary manufacturing process ensures reliable ignition and consistent combustion, delivering more thrust with less waste than conventional hybrid rockets. The global hybrid rocket propulsion market is projected to grow from $848 million in 2024 to $2.6 billion by 2032, at a CAGR of 15%. Competitors include Japan's Interstellar Technologies, Germany's HyImpulse, and Australia's Gilmour Space.
