Located about 60 minutes from Tokyo, the Riviera Zushi Marina and Riviera Seabornia Marina, both overlooking Mt. Fuji, have renewed their 'Blue Flag' marina certification for 2026. This prestigious international eco-label, a global benchmark for sustainable coastal areas, highlights the group's ongoing commitment to protecting regional marine ecosystems.
Since becoming the first in Asia to earn this certification in 2022, Riviera Zushi Marina has renewed it for five consecutive years. Riviera Seabornia Marina, which earned the distinction as the second in Asia in 2024, has now renewed it for three consecutive years. Situated on the Miura Peninsula, a region recognized by the Michelin Green Guide Japan, these two facilities account for two of the only three Blue Flag marinas in Japan and Asia, representing two-thirds of the domestic market share.
Guided by the nature-positive philosophy of 'living a rich life with nature,' Riviera has transformed its marina facilities, originally opened in 1971, into resorts that embody 'environmentally-based luxury.' Since starting marina operations in 2001, the group has engaged in diverse initiatives, including circular organic farming in the Shonan region for over two decades and recent blue carbon projects involving seaweed bed restoration. As leading sustainable marinas in Asia and Japan, both facilities aim to further drive 'sustainable tourism' centered on marine conservation, environmental education, and tourism to stimulate regional development.
To commemorate the renewal, new flag-raising ceremonies will be held in June 2026, featuring local government leaders including the Mayors of Zushi and Miura.
'Blue Flag is an international certification that requires continuous effort and higher levels of improvement every year,' says Noboru Watanabe, Chairman of Riviera Group. 'Through this certification, we are convinced that coastal environmental measures are the driving force behind maximizing tourism value. With the belief that people gather around beautiful oceans, we will continue to embody sustainable tourism where environmental commitments directly enrich the local economy and inbound tourism, connecting a rich sea to the next generation.'
