Japan's Largest* 300 Companies Exhibit: The Forefront of Rapidly Expanding Space Business with Cross-Industry Entry Gathers! The 3rd SPEXA - International Space Business Expo - Held for 3 Days from May 27, 2026, at Tokyo Big Sight

RX Japan G.K. (Headquarters: Chuo-ku, Tokyo; Representative Executive Officer and President: Takeshi Tanaka) will host the "3rd SPEXA - International Space Business Expo -," Japan's largest comprehensive space business exhibition, for three days from May 27 (Wednesday) to 29 (Friday), 2026, at Tokyo Big Sight.

Following the successful launch of NASA's manned lunar mission "Artemis II" in April 2026, global expectations for space development are rising. In Japan, the space industry is now positioned as the "most important issue" in the new growth strategy advocated by the Takaichi administration, accelerating focused national efforts and investment. As space technology begins to be utilized as a cornerstone of national strategies such as disaster prevention, communication, and advanced infrastructure, it has entered a phase of "social implementation," with successive entries from diverse industries including construction, housing, aviation, and travel. This exhibition, featuring 300 companies* (1.6 times more than last year), will be held as a "Space Business Festival" where visitors can grasp and experience the potential of Japan's new growth industry, from cutting-edge equipment leading space development to new space businesses proposed by companies close to our daily lives.

Will Space Business Save the Structural Transformation of the Automotive Industry!? Space as Japan's New Growth Industry

Due to the shift from gasoline cars to EVs (electric vehicles) and the spread of autonomous driving, the number of automotive parts has drastically decreased from approximately 100,000 to about 10,000, raising concerns about the loss of approximately 300,000 jobs in domestic parts manufacturers. Japan's core industries are currently undergoing a once-in-a-century transformation. Amidst this, "space business" is attracting keen attention as a new growth industry.

The "high reliability" and "precision processing technology" cultivated in automotive parts development, as well as the "advanced sensor technology" in the autonomous driving domain, are indispensable elements for rocket and satellite manufacturing. Especially now, as we enter the "satellite constellation era" with hundreds of small satellites being launched, and space development shifts to mass production, Japan's manufacturing prowess and extensive supply chain are becoming an opportunity to open up the global space market.

This exhibition aims to open up the space industry, which was once a "village society" of a few specialists, and serve as a bridge connecting the space industry with other sectors, thereby fostering the creation of Japanese space companies and economic growth.

【Experiential, Near-Future Technology】 From Space Solar Power Generation to Probes

The exhibition also features a wealth of actual displays of near-future technology and experiential content.

・Space Solar Cells: Sharp's actual display of solar power generation operating in harsh space environments. It was mounted on the small lunar lander "SLIM," which successfully made a high-precision landing on the moon in January 2024. It has demonstrated reliable performance in harsh environments, continuing to supply power necessary for communication with Earth for several months after landing on the moon.
