[Furikake]
Furikake is sold in small packets which are each exactly enough for one person.
Furikake can also be used for rice balls (onigiri).
Furikake originated in the 1910s in Kumamoto Prefecture where a pharmacist, Mr Suekichi Yoshimaru, developed the product to supply the calcium (in the form of the bones of small fish) which he thought was lacking in the diet of the Japanese of that time - remember that Japan was not a dairy country. Since 1934 this original ("ganso") type of furikake is produced by Futaba as "Gohan no Tomo," "Friend of Rice."
The packaging of furikake is often childish, as children also today need lots of calcium.
