Not yet as famous as ramen or sushi, humble onigiri rice ball is soul food of Japan

The word “onigiri” became part of the Oxford English Dictionary this year, proof the humble sticky-rice ball and mainstay of Japanese food has entered the global lexicon. The rice balls are stuffed with a variety of fillings and typically wrapped in seaweed. It's an everyday dish that epitomizes “washoku” — the traditional Japanese cuisine that was designated a UNESCO Intangible Cultural Heritage a decade ago. (AP Video by Ayaka McGill and Hiromi Tanoue)
