Mizuna Beach, located on Mizuna Island off Motobu-cho in central Okinawa, is said to have the cleanest ocean in Okinawa. Marine sports are recommended, but it is actually a great place to just hang out. To get there, you can join a tour or take a regular boat from Watakuchi Port in Motobu Town!
Point 1: Is the ocean at Suina Beach half as clean as it should be?

Mizuna Island has the unique nickname of “Croissant Island” because of the island’s shape, which resembles a croissant.
The ocean is beautiful everywhere in Okinawa, but tourists are used to it and seek even cleaner waters. For this reason, many people prefer the remote islands to the beaches on the main island of Okinawa.
This is especially true for snorkelers and divers.
If you want to go to a remote island such as Kerama, but you feel it is too difficult to go there, or if you want to enjoy it more casually, we recommend Mizuna Island, which is located beyond Sesoko Island! You can easily get there from Motobu-cho and rent equipment locally, so you can enjoy diving and snorkeling with ease.
Mizuna Beach is beautiful just by looking at it from offshore, but boat snorkeling is especially recommended, where you can take a short boat ride to deeper waters and see amazing coral reefs and tropical fish that only a remote island can offer. If you are lucky, you may even encounter sea turtles.
However, depending on the time of year, there are fish called gomamongara that are more dangerous than sharks, and you may cut your feet on the coral, so you may need to wear marine shoes.
There is a lifeguard on the beach even though it is free of charge, so I think it is safe to ask for his advice before doing any activities.
Point 2: Beyond Sesoko Island? How to get to Mizuna Beach?

How on earth do I get to Mizuna Beach, located on Mizuna Island, another of Motobu-cho’s famous Sesoko Islands? Many people may wonder how to get to Mizuna Beach on Mizuna Island, another of Motobu Town’s famous Sesoko Islands.

It is so convenient that there is a high-speed boat service from Tomari Port in Naha!
Point 3: “Mizuna Beach” is also good for dawdling!

When you visit Mizuna Beach, marine activities and BBQ are fun, but it is also a great place to just relax and enjoy the beautiful ocean.
To take it easy, walk along the nice cobblestone path to the other side of the island, which takes about 5 minutes.
Enjoying the beautiful scenery while listening to the sound of the waves is truly a feast for the eyes and nourishment for the soul. You can also try taking videos or photos with your favorite camera.
The beauty of “Suina Beach” is that even an ordinary scene can become a picture.
