All pairings are made before the Junisen season starts. As far as I know, the pairing is random and made by a computer program. However, there seems to be some weight in the randomness, since I have also heard that as much as possible players based in Kansai (in and around Osaka) are paired together, as are players in Kanto (in and around Tokyo). This is definitely true for the preliminary stages of most other tournaments, but I am not sure if this also holds for the pairing in the Junisen.
