Chikara Udon: Hearty Winter Noodle Soup with Mochi

Udon is one of the noodles that represent Japan, together with Ramen and Soba, and the noodle soup dish comes in many varieties.

Among them, what we Japanese often eat during cold winter months is “Chikara Udon (力うどん)”.

Chikara Udon

We call the seasonal Udon noodle soup with “Mochi (餅)” rice cake “Chikara Udon”.

Not only do some restaurants in Japan offer it during the wintertime, but the hearty noodle soup is sometimes eaten at home as well, for it is easy to prepare.

As preparation, Mochi rice cake is toasted or steamed before or during cooking.

After Udon noodle soup is made, the cooked Mochi is put on top of the Udon.

Ingredients (other than Mochi) in Chikara Udon vary depending on each household, but we typically garnish the bowl with chopped green onions.


Chikara Mochi Udon

The word “Chikara (力)” literally means “power” in Japanese, and regarding the origin of the name “Chikara Udon”, there are several theories, including the below.

One is that it is believed in Japan that Mochi brings lucky power, and another is that the rice cake is so filling that the eater can get energy from the food.


When it comes to how to prepare Chikara Udon, there are two easy/quick ways.

Note that cooked Mochi is chewy, stretchy, and very sticky, so please be cautious not to choke on it.

Instant Cup Noodles


One is to buy instant Udon and cook it. A variety of Chikara Udon cup noodles are available in Japan, including the pictured “Shiroi Chikara Mochi Udon (白い力もちうどん)” from Maruchan.
