Japan's Largest Aerospace Exhibition Held After Six-Year Hiatus

The International Aerospace Exhibition 2024 took place in Tokyo from October 16 to 19. Featuring over 600 companies from 23 countries, it is Japan's largest comprehensive aerospace industry exhibition. 

Originally scheduled for 2020, the event was delayed due to the pandemic, making this its first occurrence in six years. The defense industry presence was particularly notable, reflecting recent global political instability.

The Future of Civil Aviation

As of 2024, Japan has approximately 650 registered civil aircraft, positioning itself as a key hub in Asia. With the end of the pandemic, passenger demand for air travel is increasing. In response, the civil aviation sector is advancing research and development in lightweight materials and components to improve fuel efficiency. 

Japan is also making strides in hydrogen fuel systems, with Airbus, Kansai Airport, and Kawasaki Heavy Industries — renowned for its hydrogen technology — collaborating to prepare for hydrogen-powered aircraft. Additionally, experiments with hydrogen systems at airports are underway, generating optimism for the next-generation civil aviation market.

At the exhibition, aircraft manufacturers, parts and materials suppliers, inspection equipment makers, and information service companies showcased their latest products and cutting-edge innovations.

Technological Advancements in Space

As interest in space exploration and research grows, Japan highlighted its world-class precision and exploration technologies. Among private companies, there is a shift toward space development, leading to advancements in small and lightweight components and materials. 

Space has also become increasingly important for national security, and as India and China expand their presence in this sector, Japan's advanced technologies are attracting attention.

The Defense Industry Enters a New Phase

The defense industry had a bigger presence than usual at the exhibition, with exhibitors from the United States, Israel, South Korea, and Europe participating. A model of the next-generation fighter jet, developed jointly by Japan, the UK, and Italy under the Global Combat Air Programme (GCAP), was also on display. 

Drone demand is rising in conflict areas, with both small and large unmanned aerial vehicles (UAVs) being developed. Countries are racing to bring these drones and robots, which utilize digital and robotic technologies, into practical use. 

Japanese-developed aircraft for defense and surveillance were also on display, including fixed-wing VTOL (vertical takeoff and landing) drones. Unmanned aircraft currently being developed by the Japan Air Self-Defense Force were also featured.

The date for the next International Aerospace Exhibition in Japan has yet to be determined.
