Tokyo is the epitome of frenetic energy and jam-packed cosmopolitan culture—it’s populated by 12.5 million people. Still, it’s one of the safest cities in the world, ensuring a (nearly) carefree stay packed with pulsing nightlife, succulent cuisine and endless city experiences. Four national museums, gorgeous gardens and parks, Michelin-starred restaurants, and kooky-chic street fashions are only part of what makes Tokyo so unique. Don’t miss the Tokyo National Museum of Modern Art, the Shinjuku Gyoen National Garden and the Gwen Stefani-lauded neighborhood of Harajuku.
