This is exactly the sort of thing I like bringing back from Japan: small enough to fit in a bag, but specific enough to remind you where you bought it. The best version is usually the sealed jar, tin or packet from a normal supermarket, spice stall or food hall, not the most expensive tourist version. It is also the kind of thing you can talk about when someone asks what you brought back, because there is usually a little story attached to where you found it.

When I think of an easy, crowd-pleasing thing to bring back from Japan, Japanese KitKat flavours is a good pick because it does not need much explanation when you hand it over. I would buy a couple of packets: one to open while travelling and one to bring home unopened, because snacks have a habit of disappearing before the flight. I would rate it higher when it is locally made, clearly labelled and easy to use at home, and lower when it is just tourist packaging.
