At 10th evening-night I am having a small drinking party in Shinjuku, also gathering between the two pyramids at 18:00. There are more than 8 people attending this drkinking party and they're all cool, you should come. :) But still, if you can make 13th that would be really great! In any parties, anybody will be welcomed so just bring your friends, we can have more fun! Please let me know if you can come. Yuji
P.S. if the weather's bad there's a building overlooking the blossom, same arrangement with food etc.
