The recipe depends on which style you are making though the ingredients are usually the same with the exception of soba noodles being used in most versions of Hiroshima style Okonomiyaki. If you search you can find recipes on the internet. One thing my wife insists, is if you can't find Okonomi sauce you shouldn't make Hiroshima style okonomi, she doesn't consider it as important on Kansai style and thinks a blended sauce from soy sauce, barbecue sauce, and sweet and sour sauce is okay.
