I feel like going to this but don't know the first thing about Tokyo...
What's the address of the venue, and is there a specific hotel nearby anyone would recommend? I'm not kidding, I just finished a particularly stressful semester and will totally buy last-minute plane tickets out there.
Please note that the directions in the google map takes you to the back of the building, so you actually go past it on that map.
I took a screen shot of the entrance, I went in through these doors last time.
Its super easy to get around in Tokyo via subway. When you get into the subway station you just buy the fare from a machine, look for the "English" button on the screen, touch it and it will change everything into english and you can buy the correct fare.
