1. Okinawa: The Subtropical Paradise
Okinawa, located over 640 kilometers south of mainland Japan, is a chain of 160 islands that forms Japan's southernmost prefecture. Steeped in a rich history, Okinawa was once the center of the Ryukyu Kingdom from the 15th to 19th centuries, an independent trading nation that fostered unique cultural, political, and economic relationships with Japan, China, and Southeast Asia. This unique position in history has lent Okinawa a distinct cultural identity, differing from the rest of Japan, which is still evident today in its customs, music, dance, and cuisine.
Geographically, Okinawa is closer to Taiwan than to Tokyo, resulting in a subtropical climate that gifts the region with mild winters and warm summers. This climate allows for a vibrant array of flora and fauna, both on land and underwater, to thrive, making Okinawa a paradise for nature enthusiasts and marine adventurers alike.
Okinawa's beaches are renowned for their clear turquoise waters, powdery white sands, and vibrant coral reefs that lie just offshore. Among these, Furuzamami Beach on Zamami Island and Kondoi Beach on Taketomi Island stand out for their exceptional beauty. Furuzamami Beach, awarded two stars in the Michelin Green Guide Japan, is prized for its fine white sand and the dazzling array of tropical fish that can be seen even from the beach's edge. It is the perfect spot for sunbathing, swimming, and snorkeling.
Meanwhile, Kondoi Beach, located on the tiny island of Taketomi, offers an idyllic island experience. Here, traditional red-tiled Ryukyu houses are scattered amongst white sand paths lined with stone walls, and water buffalos leisurely pull carts amidst this tranquil scenery. Kondoi's shallow crystal clear waters are safe even for children, making it a favorite among families.
For marine adventurers, Okinawa is a treasure trove. The region's crystal-clear waters and thriving coral reefs make it one of the best snorkeling and diving spots in Japan. Okinawa is home to a third of all known coral species, resulting in reefs that brim with life and color. The Kerama Islands, located west of Okinawa's main island, are a renowned snorkeling spot. They're famous for their diverse marine life, including over 400 types of corals, vibrant schools of tropical fish, sea turtles, and manta rays.
In fact, the waters around the Keramas are so clear that they've been given the name "Kerama Blue." Okinawa also offers unique diving experiences, such as the Yonaguni Monument, an underwater rock formation off the coast of Yonaguni, Japan's westernmost inhabited island. The formation, believed by some to be the remains of an ancient civilization, offers an unparalleled adventure for experienced divers.
