【Chiba/Tateyama】Okinoshima: A Miraculous Uninhabited Island You Can Walk To

Okinoshima's greatest charm lies in its accessibility—despite being reachable on foot from the mainland, it offers a rich natural environment and crystal-clear waters reminiscent of a distant tropical paradise. Located about 500 meters off the coast of Tateyama City in Chiba Prefecture, this island became connected to the mainland due to the formation of a sandbar caused by the uplift from the Great Kanto Earthquake. Visitors can easily enjoy the feeling of exploring an 'uninhabited island'🔭.

The waters around the island are influenced by the Kuroshio Current, resulting in high transparency and a rare environment where coral reefs, considered the northernmost in the world, thrive. This makes it a living treasure trove of nature, perfect for summer swimming, snorkeling, and tide-pooling during low tide, where you can encounter tropical marine life. Although compact with a circumference of about 1 km, the island features a lush forest of evergreen trees. Walking along its trails offers a mystical exploration experience that helps you forget the hustle and bustle of city life.

In addition to its natural beauty, the island holds historical allure, with the discovery of Jomon-era underwater ruins dating back approximately 8,000 years.

The island is also home to the Okinoshima Uga Daimyojin Shrine, a popular power spot associated with the 'Legend of Encounters,' inspired by tales of abundant sardine catches. Visitors often tie red threads here as a symbol of connection.

Moreover, a cave said to have been dug during wartime offers a stunning photo spot, with its dark interior contrasting against the sparkling sea visible through its windows. Okinoshima is a place brimming with natural beauty, history, and the allure of an extraordinary yet easily accessible experience📸.
