Shibuya is ine of the busiest cities in Tokyo. It is crowded with both locals and tourists, not to menton the famous scranble crossing outside the station. Shibuya is also a city of fashion, where younger generations go to shop at stores like 109, an iconic fashion building that's been popular since the 1990's. We recommend that you bring a map when you walk around Shibuya because the number of buildings can be a little overwhelming.
