Shimizu Corporation to issue Japan's first blue bond for offshore wind vessel

Shimizu Corporation plans to issue 10 bn yen in blue bonds with a five-year maturity in January 2026. These bonds, the 38th unsecured straight corporate bonds, are primarily intended to refinance the construction of the "BLUE WIND," a self-elevating platform (SEP) vessel crucial for offshore wind power construction. This issuance represents Japan's first blue bond specifically for an SEP vessel, aligning with Shimizu’s "SHIMZ Beyond Zero 2050" environmental vision focused on decarbonization, resource circulation, and nature coexistence.

The "BLUE WIND" vessel facilitates offshore wind power generation, harnessing stable sea winds as an energy source. Shimizu has already utilized the vessel for offshore wind facility construction in Toyama Prefecture's Nyuzen offshore and Hokkaido's Ishikari Bay New Port in 2023. It has also participated in three chartering projects in Taiwan, accumulating significant construction expertise. Nomura Securities Co., Ltd. will serve as the lead underwriter for the bond issuance.

Shimizu's blue bond framework, established in December 2025, aligns with various international and domestic guidelines, including the ICMA Green Bond Principles 2025, the SBE Guide, and the 2024 Green Bond Guidelines by Japan’s Ministry of the Environment. Rating and Investment Information, Inc. (R&I) has provided a second opinion confirming this alignment, reinforcing the company's commitment to sustainable business practices and future contributions to a sustainable society.
