Musubi vs Onigiri: Differences in Detail

Musubi and Onigiri are Japanese dishes. These are rice-based round triangular or rectangular snacks that are filled with stuffing. At first glance, the two dishes may seem similar.

But when you go to experience it, you will understand the difference. Some basic differences between musubi and onigiri are:

  1. Shape: The first and most notable difference between musubi and onigiri is their shape. Where musubi is rectangular, onigiri is either triangular or oval. Due to the rectangular shape of the musubi, it can be served sliced. Onigiri, however, is triangular or oval so you can eat it with your hands.
  2. Filling: The second major difference between musubi and onigiri is the filling. Spam, teriyaki chicken or egg, etc., are used as the overall filling of musubi. In contrast, onigiri fillings, such as umeboshi (pickled plums), tuna, or salmon, are very simple. The purpose of filling the onigiri is only to fill it.
  3. Seasoning: When it comes to seasoning, you’ll often find musubi seasoned with soy sauce or other sauces. These sauces add flavor and moisture to the rice. Onigiri is commonly seasoned with salt or furikake, a spice mixture made from dried fish, sesame seeds, and other ingredients.
  4. Wrapping: You will find the difference in the wrapping style of musubi and onigiri. Musubi is often served wrapped in a strip of dried seaweed called nori. This nori gives the musubi a slightly salty taste and a crunchy texture. In stark contrast, onigiri is served both wrapped in nori or unwrapped, depending on one’s preference.
  5. Occasion: Certain dishes require an occasion to be served. As such, musubi is a popular dish among Japanese that is often enjoyed as a snack or side dish. At the same time, onigiri is a traditional Japanese snack or lunch item. You can eat it often on the go or as fast food.

So we can say that although musubi and onigiri may seem similar at first glance, they are different in shape, filling, seasoning, wrapping, and occasion in almost every way.
