1. The culture of cleanliness
Everybody I talked to asked me to be prepared for the sheer number of people in Tokyo. I was ready for the crowds . . . what I didn't expect was the cleanliness. This, despite the fact that there is no trash can in open sight anywhere in the city. You will be hard-pressed to come across a city as clean as Tokyo—Japanese people carry the trash in their hands, their pockets, or a spare plastic bag until they arrive at their destination. Alternatively, you can duck into a convenience store (which abound in the city) and dispose of your garbage there.
2. The world's most efficient railway system
Tokyo's extensive public transportation system carries 40 million daily passengers. With 13 subway lines and more than 100 surface routes run by Japan railways and other private companies, Tokyo's railway system is beyond sophisticated. With its operating speed reaching up to 320km/h, the bullet train is a rite of traveler passage in Tokyo!
