It's hard to read, but it says there's a party with girls in bikinis and international guys from different industries like the media, etc. showing up at this thing. Bikini contest with prizes for the girls.
Venue is Shampoo, a club located across the street from TV Asahi and the Roppongi Hills Tsutaya/Starbucks.
Starts at 9PM, Saturday July 10th. 2000 yen/1 free drink for general admission. Women with bikinis in hand get free admission.

EDIT: I have just learned from friends who are organizing this thing that the first place prize in the bikini contest is a free trip to Saipan.
