Top 10 Marinas in Japan
Japan does not announce itself as a sailing destination. There are no Bahamas-bright brochures, no bareboat charter fleets crowding the harbour bars. What the country offers instead is something rarer: serious infrastructure, a culture that values precision and tidiness, and some of the most scenically extraordinary coastal waters on earth. The Seto Inland Sea alone — a 450-kilometre stretch of protected water between Honshu, Shikoku and Kyushu — contains more than 3,000 islands and delivers sailing conditions that range from mirror-flat summer calms to brisk autumn northerlies. For those willing to navigate the bureaucracy and the typhoon season, Japan rewards extravagantly.
Marina Hayama, Kanagawa
Hayama Marina, located about 50 kilometres south of Yokohama on Sagami Bay, is Japan's most celebrated yacht harbour and the country's first full-service marina. It was built in 1963 and modernised repeatedly; today it holds around 750 berths, including a dedicated section for offshore passage boats. The view of Mount Fuji on clear mornings is one of the most photographed in Japanese boating. Hayama has a comprehensive chandlery, haul-out facilities up to 25 tonnes, and a long-established racing programme. The Imperial family maintains a summer villa nearby, which helps explain why the water quality here is closely monitored.
Enoshima Yacht Harbour, Kanagawa
Enoshima was the sailing venue for the 1964 Tokyo Olympics and again for the 2020 Tokyo Games, a distinction that has kept its facilities at competition standard. The harbour sits at the base of the small island of Enoshima, connected to the mainland by a short causeway. Roughly 400 berths serve resident and visiting yachts; the waterside area includes chandlery, restaurants and a direct rail connection to Yokohama and Tokyo. Prevailing summer south-westerlies push boats smartly out into Sagami Bay; Izu Peninsula anchorages are a day's sail away.
Uraga Marina, Kanagawa
Uraga occupies a strategic position at the entrance to Tokyo Bay and carries historical weight — it was here, in 1853, that Commodore Perry's Black Ships anchored and changed Japan's relationship with the outside world. The modern marina offers over 600 berths with strong typhoon-season support structures. Access to the Bay and beyond is straightforward; the marina's workshops handle fibreglass, steel and aluminium work to a high standard, making it a popular refit stop for transpacific boats routing through Tokyo.
Shin-Nishioka Marina, Aichi
On the coast of Ise Bay, Shin-Nishioka sits within reach of the Grand Shrine of Ise, one of Shinto's most sacred sites, and within easy sailing distance of Mikawa Bay. The marina is a modern facility with around 300 berths, a fuel dock and a well-supplied chandlery. The approach through Ise Bay passes the Daio headland, where the cape lighthouse is visible from several miles offshore. Summer fishing boat traffic is heavy but well-mannered; autumn sailing here is exceptional, with steady winds and warm air.
Kobe Meriken Park Marina, Hyogo
Kobe's downtown waterfront has been rebuilt into one of Japan's most accessible urban marinas. Meriken Park Marina sits directly opposite the famous Kobe Port Tower, with the Rokko Mountains rising behind the city skyline. The berth capacity is modest — around 100 visitor places — but the location puts sailors within walking distance of Kitano Ijinkan, Kobe's historic foreign settlement district, the Harborland shopping area and some of Japan's finest restaurants. It is the gateway marina for the Seto Inland Sea coming from the east.
Onomichi Waterfront, Hiroshima Prefecture
Onomichi is the eastern gateway to the Nishiseto Expressway, popularly called the Shimanami Kaidō, where a series of suspension bridges connects Honshu to Shikoku across ten islands. The small craft harbour here is used by visiting yachts as a staging point for the island-hopping route. Depths are shallow in places — 1.8 to 2.5 m — but the surroundings are extraordinary: temple-covered hillsides, narrow lanes lined with cats, and the smell of fresh ramen floating across the water.
Imabari Marina, Ehime
On the Shikoku side of the Shimanami Kaidō, Imabari is a working port that handles some yacht traffic alongside fishing and ferry operations. The marina facilities are basic but functional; the attraction is position. Imabari sits at the western end of the bridge chain, giving direct access to the fastest tidal streams in the Inland Sea — the Kurushima Straits, where spring tides run at up to 10 knots. Navigation here requires close attention to the tide tables. Get it right and the passages between the islands are exhilarating.
Hiroshima Marine Centre, Hiroshima
Hiroshima's main small-boat harbour is modest in scale but the surrounding waters are outstanding. The Aki-nada, the eastern portion of the Inland Sea around Hiroshima, contains hundreds of islands and reliable south-westerly winds through the summer months. Hiroshima itself is an hour from the marina by tram; the World Heritage Site of Itsukushima Shrine on Miyajima Island — where the famous floating torii gate stands in the tidal flats — is visible from the water on the passage through. No touring sailor in Japan should miss it.
Nagasaki Marina, Nagasaki
On Kyushu's west coast, Nagasaki has a natural harbour of exceptional depth and shelter, used by Dutch traders for over two centuries when Japan was otherwise closed to the world. The modern marina caters to a mix of fishing boats and yachts; the city's history — from the Dejima trading post to the Peace Park — rewards a longer stay. Sailing west from Nagasaki takes you into the East China Sea and within reach of the Goto Islands, an archipelago of outstanding beauty with several small anchorages that see very few foreign boats.
Naha Port, Okinawa
Naha is the staging point for offshore sailors crossing between mainland Japan and the subtropical Ryukyu Islands — a chain stretching some 1,200 kilometres south-west toward Taiwan. The waters around Okinawa are warm year-round; coral reefs require attentive navigation. The marina's facilities are utilitarian but sound; the attraction lies offshore. Kerama Islands, just 30 kilometres west of Naha, offer some of the clearest water in Japan, with visibility regularly exceeding 30 metres.
