Pop your cooked sushi rice into a large mixing bowl. Add the furikake rice seasoning and mix through evenly.
Separate the rice into equal portions, approximately one large handful for each onigiri.
Wet your hands with water and rub together with a pinch of salt.
Pick up one handful/portion of rice. If you are hiding some fillings inside, make an indent, place the ingredients inside and fold the rice over, then lightly press into a ball.
Using mainly your fingertips while resting the rice on your palm, start to press and squeeze the rice into a triangular shape, rotating as you go.
Place a slice of nori on the bottom of the onigiri, rough side in towards the rice. Then fold it up towards the middle of the onigiri.
Repeat for the remaining rice portions.
