Welcome to Tokyo, the most populous city in the world. It's easy to see why people flock to it. There's something for everyone here, from modern pop culture to ancient history.
Head to the Meiji shrine and the Imperial palace for profound cultural experiences. Akihabara and Odaiba offer robots large and small (Odaiba's is 18 meters). Don't forget Tokyo Tower, Shibuya crossing, Ginza, the Ghibli Museum, Tokyo National Museum, the Rainbow Bridge, and Tsukiji Fish Market.
Did we leave anything out? Yes. Yes, we did.
