“Sanitsu Beach” sits in Miyako Island’s Shimoji area, facing Yonaha Bay. It’s a somewhat unusual spot where one of the island’s largest tidal flats appears at low tide.
While clear water and pure-white sand spread out, it isn’t a beach for swimming; it’s beloved for birdwatching, strolling, and as the stage for the summer tradition “Sanitsu Beach Carnival.” As a hidden gem with few tourists, it’s perfect for those who want to quietly feel Miyako Island’s nature.

Sanitsu Beach is a hidden beach, without many tourists.
Since it becomes a tidal flat at Yonaha Bay, birdwatching and the like are more recommended than playing at the beach.
The Highlights of Sanitsu Beach
One of Miyako Island’s largest! A vast tidal flat that appears at low tide

The biggest appeal of Sanitsu Beach is a tidal flat that’s among the largest on Miyako Island.
At low tide, a vast expanse of sand — about 700 hectares — appears in Yonaha Bay, opening up a magical scene as if a path had emerged within the sea.
A Ramsar site! The precious natural environment of Yonaha Bay

Yonaha Bay, which Sanitsu Beach faces, was designated a Ramsar Convention wetland in July 2012.
A mangrove forest has formed along the embankment, and it’s known as a precious birdwatching site. It’s one of Miyako Island’s finest natural spots, recognized for its international value.
A birdwatching spot to meet migratory birds and sea creatures

Migratory birds sometimes fly to the Sanitsu Beach tidal flat, and it’s famous as a wild-bird observation spot, too.
Since you can enjoy a walk while observing many wild birds and creatures, it’s popular with families with children. It’s a place nature-observation lovers won’t want to miss.
The venue for the island’s summer tradition, the “Sanitsu Beach Carnival”
Locally, Sanitsu Beach is so associated with the “Sanitsu Beach Carnival” that the two come to mind together — every year around July, various sporting events are held using the tidal flat.
A summer tradition of Miyako Island, the whole island comes alive with a traditional sumo tournament, beach tug-of-war, a beach ground-golf tournament, and more.
“Sanitsu Beach Fureai Plaza,” marked by a giant Miyako-horse monument

“Sanitsu Beach Fureai Plaza,” adjacent to Sanitsu Beach, is a well-kept lawn park marked by a giant Miyako-horse monument, with a walking path, too.
There’s play equipment for children and a sumo ring, beloved as a place of rest for locals. It’s also recommended as a photo spot.
