Why it mattersThe global transition to ISO 20022 is reshaping how banks exchange financial messages. While many institutions push customers to upgrade their internal systems, Mizuho is absorbing the complexity itself—reducing friction for clients and simplifying cross-border onboarding.
A quick look at Mizuho Bank
Mizuho Bank is one of Japan’s largest financial institutions and part of the Mizuho Financial Group, a global banking organization serving corporate, institutional, and retail clients.
With a significant footprint across Asia-Pacific, the bank provides cash management, trade finance, payments, and treasury services to multinational companies operating in the region.

The new Boomi-powered portal consolidates multiple branch-level conversion tools into a unified web interface across APAC.
Clients can upload or manually enter instructions in legacy or ISO 20022 formats; Boomi automatically performs translation, validation, and secure transmission.
Centralizing the workflow has reduced operational duplication, improved service consistency across markets, and accelerated onboarding from months to weeks.
What they’re saying
“We knew the ISO 20022 transition had the potential to disrupt our clients’ day-to-day operations. Instead of pushing that complexity onto them, we decided to own it,” Andy Nam, regional chief information officer at Mizuho Bank, said in a press release on Nov. 14, 2025.
“This project allows our clients to continue using their familiar file formats while we handle the conversion invisibly in the background. That kind of simplicity requires serious backend sophistication.”
“Getting the project live in a rapid timeframe was a big win, but the real achievement is what it has enabled,” added Nam. “We’ve built a scalable foundation that not only meets current compliance needs but also adapts to the next wave of digital banking transformation.”
“Payments modernization doesn’t happen in a vacuum, it requires orchestrating old and new systems in a way that doesn’t disrupt mission-critical services,” said David Irecki, Boomi’s chief technology officer Asia-Pacific and Japan.
“Mizuho Bank’s approach blends compliance with client-centricity. By embedding ISO 20022 into a flexible integration strategy, they’ve future-proofed their operations and unlocked new ways to innovate at scale.”
What’s next
The platform is already live in key APAC markets, with broader regional deployment underway as Mizuho builds a reusable digital blueprint for future client-facing initiatives. —Vanessa Hidalgo | Ed: Corrie S. Narisma
