Getting to Fukuoka by plane
Most international participants are expected to get to Fukuoka by plane. Fukuoka airport is very close to Fukuoka city center and thus very convenient. There are frequent flights (more than every 30 minutes, 2nd busiest route in Japan) from Tokyo/Haneda, and at least a few flights per day from other major airports in Japan (Tokyo/Narita, Osaka, Nagoya, etc.). There are also international flights from most Asian hub airports (Seoul, Beijing, Shanghai, Bangkok, Singapore, etc.) and Helsinki (3 times a week).
Access to the city center from the airport is simple; you can just take a subway from the airport. Every train goes to Hakata (2nd stop, 260 yen) and Tenjin (5th stop, 260 yen) and takes only 5-10 minutes. You can walk for a 15-minutes to the meeting venue from Nakasu-kawabata station (4th stop, 260 yen) or take a bus from Hakata or Tenjin.
Getting to Fukuoka by Shinkansen
Some train freaks may like to come by bullet train. Hakata station is directly connected to Tokyo by Shinkansen, but it takes around five hours, and is rather expensive. It's more convenient to come from western cities such as Kyoto, Osaka and Hiroshima. From Hakata station, you can take a bus to the venue.
