The 90-second pitch that helps foreign founders crack Tokyo’s networking scene

Tokyo's startup scene is becoming more receptive to international founders, but language still plays a significant role in how quickly opportunities materialize. A new guide from Blackbox JP, authored by Tatsuya Yajima, reveals that while English-friendly events have increased, how a founder introduces themselves in Japanese often matters more than fluency.

Yajima suggests that while English opens doors, knowing Japanese shortens the gap once inside the ecosystem. The guide emphasizes that short, clear sentences in Japanese can help build trust and speed up execution, which are harder to achieve with translation apps or interpreters. The key is to focus on a concise self-introduction script, which should cover the founder's identity, business, intended stay duration, and interest in the market.

Yajima's guide provides a practical example of such an introduction, using a fictional New York-based AI co-creation platform founder named David. This approach zeroes in on the crucial 90 seconds after "hello" when a potential contact determines whether to follow up. The guide also highlights a local nuance: while LinkedIn is typically used for networking in many regions, Japanese professionals, especially younger ones, may prefer Instagram, TikTok, or LINE for exchanging contact details.

This guide is part of a broader conversation about the challenges founders face when expanding into foreign markets. It underscores that while policy support and capital are important, soft factors like trust, relationship pacing, and language proficiency continue to shape how quickly outside founders are taken seriously.
