Voices
A community-driven conference where you can hear real-world challenges and solutions from practitioners.
The barrier to speaking is low, making it ideal as a venue for first-time conference presentations.
Returned a year after their first visit, gave a lightning talk, and felt how much they had grown (from Bikiniki's report, in Japanese)
Joined as volunteer staff handling social media and streaming, seeing talks up close from the inside (from Yuta Shimada's report, in Japanese)

AI Expo Summer 2026
The summer edition of the AI-focused exhibition hosted by AIsmiley, operator of Japan's AI portal media. Over 100 companies present 200+ AI solutions alongside 40+ conference sessions.

Free to attend, it serves companies comparing generative AI and AI agent products.
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.
