I attended Stripe Local Fukuoka, a local community event where Stripe users share practical insights and the latest developments in payment processing. Here is a summary of the key takeaways and my own contribution to the event.

Stripe Can Process Payments Up to 99.99 Million JPY

Stripe’s per-transaction limit is 99,999,999 JPY (approximately 100 million JPY). This upper limit may not be widely known, but B2B transactions at this scale do occur in practice.

It was shared that B2B credit card transactions ranging from 10,000 to 99.99 million JPY are a real-world occurrence. Corporate cards often carry high credit limits, and there is a genuine need to process large amounts in a single transaction rather than splitting them. Stripe’s high transaction ceiling serves these use cases well.

Interestingly, business owners and executives at owner-operated companies sometimes prefer credit card payments even for transactions in the hundreds of thousands to several million JPY range, as it can be a more rational choice than bank transfer. This aspect of Japan’s B2B payment landscape shows that Stripe’s high-value transaction support is not just a technical specification but a response to real business needs.

Before Stripe Tax, Stripe Billing, and Stripe Radar Existed

I had the opportunity to share some history at the networking session. The following features, which are now standard parts of the Stripe platform, did not always exist:

• Stripe Tax: Automatic tax calculation and collection
• Stripe Billing (Subscription): Subscription lifecycle management
• Stripe Radar: Fraud detection and prevention

Before these features were available, I had to build them from scratch. This meant implementing tax calculation logic, subscription lifecycle management (trials, renewals, cancellations, proration), and fraud detection rule engines on the application side.

Today, Stripe provides all of these as platform-level features, allowing developers to focus on core business logic rather than payment infrastructure. Looking back at how Stripe has evolved, it is remarkable how mature the payment infrastructure ecosystem has become.

Conclusion

Stripe Local Fukuoka provided practical, field-tested insights that go beyond what documentation alone can offer. The specific detail about the 99.99 million JPY transaction limit and the reality of large-scale B2B credit card payments were particularly valuable takeaways.

That’s all from the Stripe Local Fukuoka Gemba.
