Shinhan Bank has taken a striking step in sustainable finance by becoming the first foreign issuer to raise transition bonds in Japan’s yen-denominated “samurai” market. On November 7, the South Korean commercial lender secured 40 billion yen (approximately $260 million) to finance projects aimed at reducing carbon emissions and boosting energy efficiency within high-emission industries.

The bonds were issued in three tranches: a two-year note at 1.322 percent, a three-year and three-month note at 1.556 percent, and a five-year note at 1.732 percent. Underwriters included Nomura Securities, Daiwa Securities and Mizuho Securities.

Strong demand from investors, particularly overseas institutions, pushed the issue size up by 10 billion yen from the original plan.

What Are Transition Bonds—and Why This Matters

Here’s the thing: transition bonds differ from traditional green bonds. Whereas green bonds are tied to projects already in environmentally-friendly sectors (think renewable energy, clean water systems), transition bonds aim to help heavy-emission industries shift to cleaner operations. In short: one supports what’s already green, the other supports what’s moving to green.

By using this instrument, Shinhan intends the proceeds to go toward energy-intensive sectors and projects that raise energy efficiency and cut carbon footprints, an important nuance for an institution committed to sustainable finance.

Why Japan’s Samurai Market?

A “samurai” bond is simply a yen-denominated debt instrument issued in the Japanese market by a foreign borrower. For Shinhan, entering this market via a transition bond achieves dual goals: access to Japanese investor capital and demonstrating leadership in ESG-linked financing. Their ability to raise this amount and at competitive interest rates both signals investor confidence and sets a precedent for other foreign issuers eyeing Japan’s transition finance market. A Shinhan official called the deal “especially significant” given growing investor interest in ESG financing.

Shinhan Bank’s ESG Credentials and Forward-Looking Ambitions

Shinhan has been issuing ESG-themed bonds consistently, this transaction marks the 13th consecutive issuance of this kind since late 2020. By spearheading the first transition bond in the Samurai market, they are positioning themselves not just as a Korean sustainable-finance leader, but as a global player in the shift toward low-carbon operations.

What this really means is they are not waiting for demand to build, they are helping shape the demand. Their bold move could encourage other high-net-emission sector companies, compliant financial institutions and even other foreign issuers to follow suit in Japan.

Looking Ahead: The Significance & The Challenges

This deal opens up new possibilities. Heavy industries that were once overlooked in green-finance narratives now have access to capital that supports their transformation. That’s a big deal.

However: transition bonds carry challenges. Defining eligibility, ensuring clear use-of-proceeds, and monitoring the actual emission reductions all matter. Investor scrutiny will rise. Also, currency, interest-rate and regulatory risk in cross-border issuance remain non-trivial.

Still, with a successful debut like this under their belt, Shinhan is stepping into a space where change is both necessary and investable.

Bottom Line

Shinhan Bank’s 40-billion yen transition-bond issuance in Japan’s Samurai market is more than a financing event. It’s a statement about the future of ESG financing: reaching heavy-emission sectors, tapping global capital markets, and bridging finance with the long-term goal of decarbonisation. For you, whether you track finance, sustainability or global markets, it is a signal that transition finance is no longer niche. It’s becoming mainstream.
