i did a quick search, and so far i've found that saffron is often used in japanese dishes that include fish (big surprise, huh) because saffron is supposed to enhance the delicate flavors of fish. this included sushi, japanese curry, and panko breaded fish balls and crab cakes.
search for "japanese recipes" saffron, and with a little digging, you should find some recipes. if you have no luck, i'll try to post some tomorrow.
