Speaking of popular Japanese cuisine, which dish would cross your mind? Sushi, Takoyaki, Shabushabu, yakiniku, etc there are so many well-known and delicious dishes. However, today we are going to introduce “Onigiri”, which you can easily find at any convenience stores or supermarkets in Japan. It has been a favorite food of lots of people. Other than the name “Onigiri”, you may have heard somewhere about “omusubi”, and some of you may have wondered which is the correct way to say it. Today, we would like to explain about onigiri’s origin, its recipe and of course, the difference between it and “omusubi”.
What is Onigiri
Onigiri (お握り or 御握り), also known as omusubi (お結び), nigirimeshi (握り飯), or rice ball, is a Japanese food consisting of white rice shaped into a triangular or cylindrical form and covered in nori. Japanese made this to fit in the palm of your hand. Locals treasured onigiri as a portable meal and bento in Japan from ancient times to the present day because it is easy to carry and eat by hand.
Originally developed as a means to preserve leftover rice or as portable food, onigiri quickly grew popular as a regular meal, and they can now distribute in convenience shops and supermarkets.
Etymology
In the Kojien dictionary, the word “onigiri” is written as “rice ball.” If you look up “nigiri-meshi”, you’ll find that “omusubi” and “nigiri-meshi” means “grilled rice”. There is also a theory that the rice ball got its name from the Japanese word “onigiri,” which means “to ward off evil spirits.”
Why is the shape a triangle?
“The most well-known theory is that they imitate the shape of a mountain.” In the past, people used to start believing that “the gods live in mountains”. Or that “when the gods come from the sky to the earth, they first descend to the top of the mountain.” At some point, this became “Mountain is God,” which means that the shape of the mountain is also the shape of God.
So why was the rice ball in the form of a mountain (a god)? The important phrase here is “omusubi,” another term for rice balls. The word “musubu” is where the rice ball gets its name. Musubu, which bind friendships and alliances, has the connotation of “connection” or “forming a strong bond.” In other words, being surrounded by a triangle is to “connect” with God.
Onigiri History
The earliest rice ball supposedly dates back to the Yayoi period. The discovery of “Japan’s oldest rice ball” in the “Chanobatake Ruins” in Ishikawa Prefecture become evidence for this.
Middle to late Yayoi period
Carbonized rice lumps in the form of rice balls were steamed and then secondary baked with sticky rice were discovered in the old Kasai-cho (now Naka-noto-cho), Ishikawa Prefecture.
Early Nara period
In “Hitachi no Kuni Fudoki,” one of the fudoki compiled by the imperial edict of Emperor Genmei, there is a description of ‘nigirii’.
Heian period
Aristocrats offered steamed sticky rice called as tonjiki to their servants during feasts. Additionally, locals claimed that they also employed this as a soldier’s portable meal.
Early Kamakura period
During the Jokyu War, locals distributed ‘onigiri rice balls with pickled plums’ to samurai on the side of the Kamakura Shogunate. This is supposed to be why umeboshi spread throughout the country. Furthermore, near the end of the Kamakura era, non-glutinous rice was introduced.
Sengoku period
Onigiri are excellent as munitions. Thinbiki-na, or “Saimeshi rice balls,” were frequently prepared using rice. After Toyotomi Hideyoshi united Japan, white rice, which produces a larger yield than red and black rice, gained popularity.
Edo period
Techniques for nori cultivation developed during the Edo period, and nori farming started in Edomae (Tokyo Bay). The gathered seaweed gained notoriety under the name “Asakusa seaweed,” and used to make square paper using Japanese papermaking techniques.
Locals learned that this type of seaweed was nutritious and had the benefit of keeping the rice from sticking to our hands when they wrapped it around onigiri, a convenient portable meal. In this way, onigiri, evolved throughout time as a result of new technology and innovation, is still valued as daily comfort food in Japan in addition to being a popular portable dish.

Difference between Onigiri and Omusubi
Difference in shape
It is also somewhat related to the “god of rice balls”, but it seems that in ancient Japan, locals offered rice balls to the gods. Also, there is a theory that rice balls shaped like triangular mountains were called ‘omusubi’ because there was a custom that mountains is related to gods since ancient times. Onigiri, on the other hand, is said to have changed its name from rice ball to onigiri without any particular shape. Although there is no specified shape such as a triangle or a bale shape, it indicates stuffed rice.
Regional differences
Locals mainly called onigiri, “omusubi” in eastern Japan, and onigiri in Kansai. However, there is also a theory that it was called onigiri in eastern Japan and omusubi in western Japan.
Good rice for onigiri
In terms of graininess, proper hardness, mouth untie, and tolerance, “Tsuyahime” from Yamagata Prefecture topped the list in all four categories. However, Tsuyahime’s evaluation differs depending on the person. People who like ‘Koshihikari’ don’t like ‘Tsuyahime’ because it’s too strong, and people who like ‘Koshihikari’ tend to like ‘Nikomaru’ as well. ‘Tsuyahime’ has a distinct graininess, but ‘Nikomaru’ has a relatively higher sweetness and flavour.
