Takenaka Corporation to Exhibit at the 3rd SPEXA - International Space Business Exhibition

Takenaka Corporation will participate in the 3rd SPEXA - International Space Business Exhibition, taking place from May 27 (Wednesday) to May 29 (Friday), 2026, at Tokyo Big Sight South Hall. The exhibition hours are 10:00 to 17:00, and admission is free with reservation via the official website (https://www.spexa.jp/tokyo/ja-jp/visit.html). The event is organized by RX Japan. The company's exhibit, themed "Build with us: Creating life on the Moon," will present technologies, development scenarios, and future visions for enhancing "space QOL" in lunar habitation through models and immersive experiences. This includes gradual construction and operation scenarios from short-term stays to long-term settlement. For the first time, structural technologies like lunar regolith solidification blocks and environmental control technologies essential for lunar habitation will be introduced. Realizing lunar habitation requires collaboration across diverse fields such as materials, robotics, ICT, medicine, energy, and environmental control. The exhibition aims to create new connections with partner companies, research institutions, and policymakers involved in technology development, demonstration, and commercialization. Exhibition highlights include: - Immersive experience with visiMax®: A wide-angle visual simulator developed by Takenaka Corporation, allowing visitors to experience a life-sized lunar living space for design review, operation verification, and risk assessment. - Model exhibits: Displaying gradual construction and operation scenarios on a lunar environment model, from initial exploration to long-term settlement. This includes a short-term stay module for closed environments (in collaboration with the University of Tokyo's Jun Sato Laboratory under the MLIT/MEXT "Space Unmanned Construction Innovation Technology Development / Stardust Program"), a long-term operation module for 40 specialists, a 150m vertical deployment structure "Luna Tower" as an infrastructure core, and "Luna Dome" for living and research in craters/vertical shafts. - New technology development for space architecture: - Lunar regolith solidification blocks: Research and development of construction materials using only lunar regolith as raw material, requiring no water or firing energy. This technology, based on in-situ resource utilization (ISRU) on the Moon, is expected to reduce transport costs and contribute to large-scale base formation. Applications include protective walls and road paving for lunar facilities. (In collaboration with Associate Professor Tatsuya Onshina's Lunar Base Development Laboratory at Tokuyama College of Technology). - Hybrid panel structure system: Modular polygonal hybrid panels composed of metal outer frames with excellent weldability in vacuum and lightweight, high-strength surface materials. Intended for large living structures from low Earth orbit to the future Moon. It proposes design and panel connection technologies to build dome-shaped spaces with high airtightness and structural strength, aiming to contribute to sustainable lunar activities and the formation of a space industry foundation. Takenaka Corporation is also a collaborating institution in the "Space-related Medical Integrated Living Space Development Hub" (representative institution: Tokyo Tech), adopted under the "Space Utilization and New Industry Seed Creation Hub (SX-CRANE)" fund. The exhibition will present plans for technology development aimed at realizing healthy and comfortable space living environments.
