Although I have been through the airport (Narita) many times, this was my first actual visit to Japan. We stayed in Yokosuka, but made the trip to Tokyo everyday. The train system is quite confusing if you've never taken it before, but eventually we got it all worked out.
Signs like this always make me curious. Obviously, they are trying to attract foreigners, since the sign is in English, but what does in mean "standing and no charge". I'm always curious to check out places like this.
I wouldn't say that there is a lot of green space in Tokyo, but often you would come across small parks as you were transiting from one place to another. This was a small Shinto shrine located in a park near the Tokyo Tower.
So, we went to this restaurant for "hot stickers", and the waitress showed us to this machine outside. You buy a ticket from the machine (like a movie ticket) and you give it to the waitress who then brings you your food. Once we tried this, we started noticing that it wasn't at all uncommon in Tokyo to see these things.
