When I was in Tokyo, I read a "What's going on" pamphlet while I was there informing me of the "Anime Festival" going on. Unfortunately, I read said pamphlet at 4:00 pm so it's too late to go that day (about a 90 minute trip). Fortunately, it mentioned that it would take place from March 23-26. Great, I could go on the Monday and Mark could go with me. So Monday morning when we checked the Net we discovered that it did in fact end on the Sunday and so I missed out on the gig. Dagnabit!
These pics are examples of what I could have seen and here's a place where you can see a few more pics!
