History of Furikake
In the early Taisho period (around 1912), Mr. Suekichi Yoshimaru of Futaba, a pharmacist, came up with the idea to make a product with ground fish bones to compensate for a lack of calcium in the Japanese diet.
Small fish were dried, ground, seasoned, then mixed with sesame seeds, poppy seeds and Aonoriko (seaweed) to cover up the fish flavor (So the people who don't like fish can enjoy it too). Then, the mixture was bottled for sale.
This is the first Furikake "Gohan no Tomo" (Rice's Friend), and this product is still produced and sold by Futaba today.
