If you have the misfortune of visiting Tokyo for only a few days, you’ll find it hard to decide where to spend your time in a city that has so many amazing things to see and do. A good way to get a sense of the traditional, slower-paced Tokyo, as well as the modern, fast-paced Tokyo in a single day is to venture to the northeastern district of Asakusa in the morning, with its temples and buildings dating back to the 1950s (Tokyo was essentially leveled in the WWII fire-bombings, so the 50s is considered old for Tokyo architecture). Then take a cruise south on the Sumida river, which will take you under about a dozen architecturally distinct bridges. The cruise ends on the man-made island of Odaiba in Tokyo Bay, which offers endless attractions for modern shopping and hi-tech fun, and even a sandy beach. At the end of the day (or night), head back to the mainland on the Yurikamone line, which does an entirely gratuitous 360° loop as it crosses the river, giving you a panoramic view of eastern Tokyo.
