Riviera Zushi and Seabornia Marinas Achieve Remarkable Blue Flag Sustained Certifications

In an impressive showcase of commitment to environmental sustainability, Riviera Group's Zushi Marina and Seabornia Marina in Kanagawa Prefecture have announced that they have successfully renewed their Blue Flag status for another consecutive year. The Zushi Marina has maintained this esteemed international environmental certification for an uninterrupted five years since becoming the first in Asia to receive it in 2022. Meanwhile, Seabornia Marina celebrated its third consecutive year of retention since securing its certification as the second Blue Flag marina in Asia in 2024.

Dwelling among the stunning scenery of the Miura Peninsula, these marinas occupy a significant position in Japan, representing two of only three Blue Flag certified marinas in the country. Given that they account for a substantial two-thirds of Japan's total Blue Flag facilities, Riviera Group continues to uplift the standard for sustainable coastal tourism.

Environmental Commitment and Local Impact

Riviera's mission, stemming from its ideation of living harmoniously with the environment since its inception in 1971, has transformed these marinas into exemplary models of luxury that closely adhere to sustainability principles. Through ongoing initiatives, including regenerative agriculture in the Shonan region for over two decades and marine habitat restoration endeavors, Riviera demonstrates a profound commitment to regional ecological conservation.

Both marinas operate under a philosophy that underscores sustainable tourism — underlining that environmental efforts are pivotal to enhancing tourism value and driving economic opportunities in local communities. The strategic focus on ocean conservation, education, and tourism creates a synergistic approach that Riviera aims to promote in communities both in Japan and across Asia.

Upcoming Celebratory Events

In recognition of the continued Blue Flag certification, a flag-raising ceremony will be held in June 2026 at both marinas, attended by local government officials and stakeholders. This event symbolizes not only the achievement but the commitment to ongoing improvement in marine conservation.

Insight from Riviera's Leadership

Chairman Watanabe Akira of Riviera Group expressed pride in achieving and maintaining such a distinguished global standard, highlighting that the Blue Flag accreditation reflects a continuous pursuit of higher environmental standards. He notes that the initiative reinforces their belief that ecological responsibility is key to maximizing tourism potential: “Beautiful seas attract visitors,” he stated, emphasizing the intertwined nature of sustainable tourism and local economic benefits.

Local Government Support

Zushi City Mayor Kirigaya Satoru hailed the marina's sustained accomplishment as a point of community pride, recognizing the essential leadership role Riviera plays in promoting environmental stewardship. Similarly, Miura City Mayor Deguchi Yoshikazu articulated gratitude for Riviera's contributions to environmental education for youth through marine programs and aspirations for the Blue Flag to become a new emblem of sustainable tourism.

Understanding the Blue Flag Standard

Blue Flag is one of the finest international environmental certifications established by the Foundation for Environmental Education (FEE) in Denmark. This program evaluates sustainable coastal regions, including beaches and marinas, based on comprehensive criteria relevant to the 17 Sustainable Development Goals (SDGs). Out of thousands of sites globally, only a small fraction — approximately 700 marinas, amounting to just over 13% — have been awarded this prestigious status due to the rigorous requirements involved.

The continuous assessment includes a two-tier evaluation process involving national and international reviews, ensuring that marinas must surpass their previous year's achievements to maintain their status. This process reinforces the validity and prestige of the Blue Flag certification.

Current Blue Flag Certification in Japan

As of May 2026, Japan boasts a total of 15 Blue Flag certified locations, including three marinas. Riviera Zushi Marina, with its striking palm-lined landscape and proximity to Mount Fuji, was inaugurated in 1971, while the historic Seabornia Marina, established in 1967 amidst the breathtaking scenery of Miura Peninsula, has become a favored locale for yachters.

Conclusion

Riviera Zushi and Seabornia Marinas serve as shining examples of how environmental dedication can significantly benefit tourism and local economies. Their celebration of continued Blue Flag status is not just a testament to their success but also an ongoing promise to future generations for sustainable marine environments at the heart of Japan's thriving coastal tourism.
