But it's very crowded, and I was disconcerted by people bumping into me with no regard and no mumbled reciprocal 'pardon me', 'excuse me', in Japanese, English, or any other language. Someone told me later on to stop excusing myself because no Asians say it or expect it. There's just too many people and they'd be saying it non-stop. Lesson learned.
So if you go to Tokyo, be sure to take a day to stroll this area. The sights, sounds, and smells will amaze you. And don't worry about saying 'excuse me' when you bump into someone.
