From deep tech, space, and biotech to pitch contests and global expansion—the way Japan’s regional startup ecosystem connects with global investors is undergoing a transformation. 

Deep tech, space industry, biotech, materials, IP strategy. Recent regional startup events in Japan are no longer just for local companies. They are rapidly transforming into international collaboration platforms where overseas investors, accelerators, global corporations, and universities participate together. In the midst of this transformation, what matters most is not just technology itself, but clear communication that allows each party to accurately understand one another's technology and strategies. 

Especially in startup events where overseas investors, accelerators, and foreign local governments gather, complex discussions take place regarding technical validation, market entry strategies, investment terms, and support policies. Accurately understanding presentation content as well as every piece of technical jargon is a crucial element that drives actual collaboration. 

For this reason, real-time AI interpretation (AI Interpretation) and live multilingual captions (Live Multilingual Captions) are becoming established as the new essential event infrastructure at regional startup conferences in Japan. 

DATERISE! 2026: Connecting Sendai and Tohoku to the World 

DATERISE! 2026 was held on September 5 at the Sendai International Center Exhibition Hall in Miyagi Prefecture, Japan. Co-hosted by Sendai City, Tohoku University, the Tohoku Bureau of Economy, Trade and Industry, Miyagi Prefecture, JETRO Sendai, and the Sendai/Tohoku Startup Ecosystem Consortium, and operated by 01Booster, this event was not merely a startup exhibition. It served as a flagship open innovation platform connecting Tohoku's regional technologies to the global market. 

At the event, startups across various sectors—including deep tech, space, biotech & healthcare, materials, agrifood, robotics, and edtech—took to booths and pitch stages to meet with domestic and international investors, major enterprises, and support organizations to discuss investments and business collaborations. 

Sessions ran concurrently across two main stages: DATERISE! STAGE and FRONTIER STAGE. The exhibition floor featured over 100 booths in total, including 42 dedicated startup booths. 

As an official event sponsor of DATERISE! 2026, EventCAT facilitated seamless multilingual communication across the event. The company delivered real-time AI interpretation and live captions for stage sessions while operating an interactive exhibition booth for attendees. 

Two Concurrently Operated Stages Without Translation Booths 

The highlight of the event was the afternoon pitch contest, "DATERISE! THE PITCH." Over 120 minutes, 10 startups took to the stage in rapid succession to present their businesses. The judging panel featured partners from Flagship Pioneering, Mitsui Sumitomo Insurance, Darwin Venture Management, and Singapore-based investment firm Meet Ventures. With a U.S. market expansion program awarded to the winner, the stage was filled with intense energy focused on global reach right from the start. 

Because multiple sessions take place simultaneously at global startup conferences, assigning professional human interpreters to every stage is often difficult. Even with two stages running concurrently, the multilingual sessions were successfully operated using EventCAT’s real-time AI captions alone—without separate translation booths or simultaneous interpreters. 

The session operations ran smoothly without sacrificing floor space for translation booths or managing interpreter schedules, thanks to an operational setup that tailored screen layouts for both main displays and personal devices. Even with tight 5-minute turnover times between sessions, changing language settings was all it took to adapt when language configurations shifted. 

Consecutive Pitches from 10 Startups: AI Captions Bridging Presenters and Judges in Their Own Languages 

The highlight of the event was the afternoon pitch contest, DATERISE! THE PITCH. Over the course of 120 minutes, 10 startups sequentially took the stage to present their businesses. The panel of judges included representatives from Flagship Pioneering, Mitsui Sumitomo Insurance, Darwin Venture Management, and a partner from Singapore-based investment firm Meet Ventures. With a US market entry program awarded as the grand prize, the stage was designed from the outset with global expansion in mind. 

EventCAT provided real-time AI captions for presentations conducted in Japanese. A key feature was the ability to configure different screen layouts for the speaker and the main audience screen. On stage, presenters could view a monitor displaying translated captions during Q&A to answer questions seamlessly, while attendees in the audience followed the flow of the presentation in real time via large screens or personal devices. 

The goal of a startup pitch is not just delivering a great presentation, but starting a conversation with investors. Real-time AI captions ensured that this initial conversation was never interrupted by language barriers. 

From Stage Sessions to Booth Discussions  

Beyond stage session support, EventCAT operated an exhibition booth during the event. The EventCAT booth welcomed visitors from diverse backgrounds, including local government officials, university representatives, startup support organizations, and corporate open innovation managers. Most visited the booth after experiencing the real-time captions during stage sessions. 

Inquiries generally fell into three categories: first, supported languages and translation accuracy; second, applicability to their own event formats; and third, implementation procedures, including pre-learning domain terminology. 

Because visitors came after seeing the system live in action, conversations skipped 'What is this?' and jumped straight to 'How can we apply this to our own events?' This enabled us to spend our brief booth meetings on actionable deployment strategy rather than basic product intro. 

Accurate Delivery of Specialized Terminology: From Deep Tech to IP Strategy 

Investors must understand the technology in order to invest. Thus, ensuring that presentation content is accurately conveyed is one of the most critical elements in any startup event. 

At startup events, terminology often appears that general machine translation tools struggle to accurately convey. For instance, terms such as: 

• Deep Tech

• Spinout

• Rockoon

• IOWN

• SBIR

• IP Strategy

• Spaceport

• Pre-Series A

can shift in meaning if the industry context is not properly understood. To address this, EventCAT pre-loaded presentation materials, company names, technical terminology, and program titles ahead of DATERISE! 2026 to maximize AI translation accuracy. 

As a result, even during real-time Japanese-to-English translation, industry-specific expressions unique to deep tech were communicated seamlessly. This enabled participants to fully focus on deep-dive discussions, not only during stage presentations but also in subsequent booth consultations and business matching sessions. 

AI Interpretation: The New Infrastructure Connecting Regional Ecosystems to the World 

Japan’s regional startup ecosystem is rapidly shifting from merely introducing local companies to serving as an international collaboration platform connecting global investors, enterprises, universities, and public institutions. In this evolving landscape, real-time AI interpretation is transcending simple language translation to become a vital communication infrastructure connecting startups with investors, and regional ecosystems with the world. 

As cross-border collaborations expand, the ultimate goal is no longer just translating languages, but connecting entire ecosystems. 

DATERISE! 2026 demonstrated that real-time AI interpretation is far more than a convenience feature—it is an essential global communication infrastructure that bridges regional startups with overseas investors, universities with corporations, and Tohoku with the world. 

Backed by proven experience across startup events, global investment summits, open innovation programs, demo days, and international conferences, EventCAT delivers optimal multilingual communication environments tailored to any event scale or operational format.
