Wrapped in the aroma of seaweed, a small triangle of comfort holds the heart of Japan.
What Is Onigiri?
Onigiri, or rice balls, are a traditional Japanese snack made by shaping freshly cooked rice by hand, often with a bit of salt and a savory filling inside. Common shapes include triangles, ovals, and rounds, and they are frequently wrapped in a sheet of nori (dried seaweed), making them easy to eat without utensils or mess.
Inside, you’ll find ingredients like pickled plum (umeboshi), salted salmon, bonito flakes, or seasoned kelp—flavors deeply rooted in Japanese cuisine and culture. The simplicity allows the quality of the rice and ingredients to shine.
A History Carried in the Palm of Your Hand
The origins of onigiri date back thousands of years, with remnants resembling rice balls found at archaeological sites from the Yayoi period. Valued for their portability and staying power, onigiri became a staple for samurai during the Sengoku era and have continued to be a beloved part of Japanese meals—whether as a quick breakfast, part of a lunchbox, or a snack on the go.
From Tradition to Innovation
While classic Japanese fillings remain popular, today’s onigiri come in countless creative varieties. Tuna with mayonnaise, grilled meat, seasoned ground chicken, cheese—the possibilities are endless. Convenience stores across Japan make them easy to find, but specialty shops focusing on quality rice, careful preparation, and artisanal ingredients are also gaining popularity.
