Japanese Playstation 3-owners can rejoice today, since Sony have now announced that the Playstation Store will return in full force to the Japanese PSN this week. The store will come back up on April 6, on Wednesday in other words, according to the announcement (translated by Andriasang). Sony never gave an official reason why it wasn't brought back earlier, but various sources have pointed at the Japanese government and credit card companies not trusting their security as the probable reason.
