With 10 billion eaten every year, onigiri (rice balls) are one of Japan’s most popular foods. They combine rice, salt, nori seaweed and a filling to create a simple meal, perfect for eating on the go. This time on Japanology Plus, our theme is onigiri: rice balls. Our main guest is Yusuke Nakamura, Representative Director of the Onigiri Society and a man who personally eats 3,600 rice balls a year. And in Plus One, Matt Alt visits an onigiri specialty store to learn how to make one himself.
