Japan Fusion Technology Showcase Powered by Plug and Play Japan
Showcasing Japan’s Fusion Technology Edge and Building the US–Japan Bridge for Capital and Collaboration

■Overview Japan Fusion Technology Showcase is an event designed to showcase Japan’s advanced fusion technologies and industrial capabilities to investors, corporations, startups, and ecosystem stakeholders in the U.S. and Silicon Valley, while creating new opportunities for Japan–U.S. collaboration, investment, and business development. The commercialization of fusion energy requires much more than the reactor itself. A broad range of industrial technologies—including superconductivity, advanced materials, fuel-cycle technologies, heating systems, plant engineering, and critical components—will play an important role. In addition to pitches from Japanese fusion startups and companies, this event will explore the commercialization of the fusion industry and the potential of a global fusion ecosystem from the perspectives of Japanese corporations, CVCs, and U.S. investors. Plug and Play will serve as a bridge between Japan and the United States, creating new connections within the Japan–U.S. Fusion Ecosystem. ■Who Should Attend ・Companies and investors interested in fusion technology and business development ・U.S. companies and investors seeking investment and collaboration opportunities with Japanese deep-tech companies ・Fusion-related startups, CVCs, corporations, research institutions, and engineering companies ・Professionals exploring technology partnerships, joint ventures, and U.S. expansion opportunities with Japanese companies ■What You Will Gain ・Insights into the latest technologies and business developments from Japanese fusion startups and companies ・Perspectives from Japanese corporations, CVCs, and U.S. investors on the commercialization of fusion energy ・Potential investment, technology collaboration, and business development opportunities between Japan and the U.S. ・Networking opportunities across the fusion ecosystem, particularly in Silicon Valley ■Featured Fusion Startups Three Japan-born Fusion Startups will showcase their technologies and business strategies, each taking a different approach toward the commercialization of fusion energy. Helical Fusion|Fusion Reactor A Japanese fusion startup pursuing the commercialization of fusion energy through a uniquely Japanese helical fusion reactor approach. By integrating key technologies including high-temperature superconducting magnets and blankets, the company aims to demonstrate fusion power generation in the 2030s. Portfolio company of Plug and Play Japan. Yosuke Kubo|Executive Officer, COO Heads the business development function. Prior to joining Helical Fusion in 2023, he spent approximately 15 years at Mitsui & Co., working in energy business development, resource development, M&A, and related fields. LiSTie|Lithium Recovery / Fusion Fuel Cycle Based on research originating at the National Institutes for Quantum Science and Technology (QST), LiSTie is developing a high-purity lithium recovery technology based on its proprietary LiSMIC (Li Separation Method by Ionic Conductor) technology. The company aims to apply its technology to the stable supply of lithium resources required for the fusion fuel cycle. LiSTie was selected for and supported through Plug and Play Japan’s Tokyo SusHi Tech Global and accelerator programs. Takeshi Hoshino|Representative Director & CEO The inventor of LiSMIC, he conducted research on lithium required for fusion reactor fuel production at QST and founded LiSTie in 2023. JSA (Japan Superconductor Application Development)|Superconducting Materials / Magnets JSA is developing ultra-fine superconducting wires with world-class levels of flexibility and low AC loss. The company aims to apply superconducting materials such as MgB₂ to coils and magnets for next-generation energy technologies, including fusion reactors. Keita Kojima|Executive Officer, COO Responsible for business development and corporate planning. After working in business development and organizational management in the renewable energy sector, he joined JSA in 2025. ■Featured Corporate / Investment Speakers Kazumi Sato|Executive Officer / Vice Executive Conductor, NOVARE, SHIMIZU CORPORATION Powered by Plug and Play Japan Date & Time: November 4, 2026 (Wed.), 9:00–10:30 Venue: Plug and Play Tech Center, Sunnyvale Format: In Person (Limited Seats) ■Agenda 9:00 - 9:05 Opening Phillip Vincent, CEO Plug and Play Japan 9:05 - 9:15 Greeting Speech Y.
