Innovation Japan 2026 (University Trade Fair)
Japan's largest university-industry matching event, hosted by the Japan Science and Technology Agency (JST). Patented technology seeds from universities nationwide are exhibited for matching with corporate R&D and new business teams. The 2025 edition drew about 14,000 visitors to 291 exhibited seeds. Less a startup conference and more a trade fair that seeds technology transfer and joint research.
Open Developers Conference 2026
A developer-focused open source conference run by the OSPN community behind the Open Source Conference (OSC) series. Billed as an "open source culture festival," it packs seminars, hands-on sessions, and community booths on DevOps, dev tools, and cloud into a single free day. Modest in size at 100-plus attendees, its strength since 2018 has been direct access to the developers behind OSS projects.
