Not just condiments, my match sent a massive package of Japanese whatnot! :D

There's some sort of curry sauce, rice, panko breadcrumbs and a packet of something I can't read. Problem is, I don't have a clue what to do with it! Going by the label on the rice it's all for something to do with sushi, but I can't say I've ever had it. This is going to take some figuring out, anyone have any pointers?
