Once the great Shogunate trading centre of Edo, Tokyo became Japan’s capital in 1868 and has since grown into one of the world’s most populated metropolises. Each of Tokyo’s 23 wards is practically a stand-alone destination, connected by excellent transportation systems. Asakusa, Ginza, Shinjuku, Shibuya, and Roppongi Hills are among the most popular itinerary options. Climb one of the observation towers or visit a roof top bar to get a sense of the sheer scale of the magnificent city.
