Furikake is a dry Japanese seasoning meant to be sprinkled on top of cooked rice, vegetables, and fish. It can be used to make Japanese rice balls (Onigiri) and Japanese rolls like (California Maki)
It typically consists of a mixture of dried fish, sesame seeds, chopped seaweed, sugar, salt, and monosodium glutamate. ... Furikake is often brightly colored and flaky.
As such, the most well-known and accepted way of using furikake is to tear open a sachet and sprinkle it over a serving of rice, whether that be hot, steamed rice fresh from the rice cooker/saucepan, cold rice from the night before, or rice that is going into a bento box for lunch.
