Seabonia Marina
The origin of a resort marina in which beautiful nature can be enjoyed to the fullest.
Seabonia Marina, located in Koajiro Bay, the southern end of Miura Peninsula is an old established marina filled with nature. “Koajiro’s Forest” is behind the marina with the headwaters as well as the ocean’s ecosystem untouched. Numerous mediums have called attention to this spot. It is highly recommended that you enjoy the restaurants within the marina by eating and gazing out at the Sagami Bay after a stroll in the forest. The Seabonia Marina offers an affluent cruise plan for those who do not own a boat. With the ocean and forest, Sagami Bay’s nature can be enjoyed at this marina.


■ Marina Encompassed in Sagami Bay’s Nature
Seabonia Marina came to life in 1967. Not only can you enjoy the ocean, but can you take advantage of the woods and the outdoor life that it has to offer. Let’s revel in the untouched nature.
■ “Koajiro’s Forest”
The woods and tidal flat come together as one, with many unique ecosystems remaining untouched.
■ Seabonia Clubhouse Restaurant
Anyone and everyone are welcome. The view of Sagami Bay can be enjoyed with your meal from any seat at the restaurant.
■ Seabonia Rice
A pilaf of high quality with an abundance of seafood—the restaurant’s highlight.
■ Cruising
Plans are rich with ones that visitors can benefit from. Our veteran staff will steer the wheel and cruising can be enjoyed.
