I always enjoyed walking from Shinjuku JR station to my previous company, several blocks away. It's always crowded like crazy in Shinjuku especially in the morning where people rushing to be in their office on time. And you can easily get carried away and forget the beauty around you. Like a cute flower shop near the station entrance, a paved street outlined with trees, cafes… Sometimes, it's better to slow down once in a while and observe the surrounding.
