Sony is celebrating Japan's Golden Week with a promotion that discounts various Japanese games. The sale will run all this week, and offer pretty sizable discounts on Japanese games like Chrono Trigger, Persona 4 Golden, and Metal Gear games.
The PlayStation.Blog lists a couple dozen games for sale. Discounts range up to 50% off, or up to 75% for PlayStation Plus users. A few notable deals include both Chrono Trigger and Chrono Cross ($4.99/$3.49), Metal Gear Solid HD Collection ($19.99/$11.99 on PS3, $14.99/$8.99 on Vita), and the fairly recent Ys: Memories of Celceta ($27.99/$19.59). The sale will start tomorrow with the PlayStation Store update.
