Kozushima Island, also known as Kōzu-shima, is a hidden gem in Tokyo, perfect for beach lovers and adventure seekers. I, Ryu, visited this island and was captivated by its pristine sandy beaches, crystal-clear waters, and excellent snorkeling spots, making it a great place to relax and explore marine life. Hiking up Mt. Tenjyo rewarded me with breathtaking views, and at night, the island, designated as a Dark Sky Island, offers an unforgettable stargazing experience—I’ll never forget the countless stars I saw on the beach. The beaches had a quiet, private feel, with almost no one around. Driving around the island was also a fantastic way to enjoy the beautiful scenery, though it's important to book a rental car early since availability is limited. Whether you're splashing in the turquoise waters or gazing up at the star-filled sky, Kozushima is a natural planetarium waiting to be discovered.
