National Rice Ball Day is a holiday observed annually on April 19th that encourages everyone to enjoy rice balls on this day. Also known as omusubi or onigiri, Japanese rice balls are typically found in bento boxes and are shaped into balls or sometimes triangles by hand.

They are readily available at convenience stores across Japan and are as common to the Japanese as sandwiches are to Americans. It should be no surprise that this is the case. After all, they’re portable, easy to eat, and taste very good as well. All these are good enough reasons for people to observe this holiday and enjoy some rice balls themselves.

The History of National Rice Ball Day

Rice balls have been made in Japan for hundreds of years and can be traced back to the 11th century. Back then, they were called tonjiki and quickly became a popular addition to travelers’ lunches.

In the United States, rice balls haven’t always been very common. In fact, up until the 1980s and 1990s, rice balls were made by hand, which means that they could only be found at upscale Japanese restaurants.

That changed when triangular onigiri began to be made by a special machine. Now, rice balls are quite common in the U.S. and can be found just about everywhere. If rice balls aren’t available in a person’s area, they can always make their own following one of the many recipes that can be found on the internet.
