When it comes to Japanese cuisine, one can only be amazed by its diversity. The variety of authentic dishes is truly dazzling with noodles being an absolute standout. Some of their types are talked about more than others, for instance, ramen noodles. But it doesn’t mean that the rest should be left behind.

Have you ever heard of soba noodles? And what about udon? This is when it becomes confusing. Lots of people usually mix up these two noodle types. Nevertheless, the difference between udon and soba exists and it goes way beyond the looks. 

Want to know what is the difference between soba and udon noodles? Stay tuned! We’re going to cover a lot of details about the udon vs soba battle.

What are soba noodles?

Soba noodles are mostly made of buckwheat flour, wheat flour and water. In the Japanese language the word “soba” means “buckwheat”, so it certainly makes sense. These noodles have a brownish colour and a rich nutty taste. 

Although they may be served as a separate dish, soba noodles are an irreplaceable ingredient for multiple traditional recipes. 

Soba Noodles


The tradition of eating soba noodles flourished during the Edo period. At that time, each eating establishment served soba noodles together with sake and other Japanese meals. 

Local people preferred them to simple white rice, due to the number of nutrients and vitamins they contain. Thus, being richer in taste and healthier than other food of the period, soba noodles gained popularity. 

The rest is history. But there are quite a few different varieties of soba noodles that have appeared over this time.

Varieties of soba

When talking about soba noodles, we should understand that there is more than just one way to cook them. Different ingredients, preparation styles and areas of origin really influence the dish and add some uniqueness. 

So, let’s have a look at the most common varieties of soba noodles out there.

What are udon noodles?

Japanese cuisine cannot be imagined without udon noodles either. These are thick and chewy noodles, made of wheat flour, salt, and water. People eat them not only in Japan but also in many other countries around the globe. 

Udon can be cooked in a multitude of ways, either as a separate dish or as a component of a complex staple. You can find udon noodles in cold and hot dishes, fried with meat or vegetables, and topped with tofu, prawns, kamaboko and lots of other options.  


Just like soba, udon noodles have their roots deep in history. However, their origin is even dimmer, leading to the creation of various tales and legends.

One of the legends has it, that one of the Rinzai monks once travelled to Song China where he discovered the technology of flour milling. Later on, he brought it to Japan. After that, the locals learned how to make udon and soba, and spread their experience across the country.

Here is also a different story, that refers to the Heian Era and a priest called Kukai. He happened to study in Tang Dynasty China where he also learned what udon noodles were. Over time, this knowledge reached the small Japanese island of Shikoku and grew into what we know today as udon noodles. 

Many other tales can be mentioned here as well. But for the small details, the main idea remains unchanged. The tradition of eating noodles came from China and evolved into one of the most beloved foods of the Japanese people.

Main Difference Between Udon and Soba Noodles

So far some many new facts, right? As you might have noticed, soba and udon noodles have lots of things in common, especially when it comes to the ways to consume them. 

At the same time, there is more than meets the eye. So why not have a closer look at the difference between soba and udon? 

1. Appearance 

The most striking difference between soba and udon is perhaps their appearance. Soba noodles are long, thin and characterised by various hues of brown colour. While udon strands are much thicker. They are white, glossy, and chewy.  

2. Ingredient

Udon noodles are mostly made of wheat flour, water, and salt while the main ingredient of soba noodles is buckwheat flour. 

Sometimes a certain amount of wheat flour is added to soba as well. The proportions may vary, of course. So you should read the labels carefully if you’re looking for a specific ratio.

3. Flavour and texture

Udon noodles have a rather neutral flavour which makes it easier to play around and create interesting combinations. When it comes to structure, udon strands are mild and chewy. 

On the contrary, soba noodles have a rich nutty taste that benefits various recipes. Their amora and chewiness depend on the amount of buckwheat flour added. But they are typically not as mild as udon. 

4. Nutritional value 

When the concept of healthiness is concerned, soba noodles take the cake here. Since they are made of buckwheat flour, they have a lower gluten and calorie amount which is perfect for a healthy diet. 

The main ingredient of udon noodles is wheat flour. Thus, they cannot be called gluten-free by any means. Nevertheless, they are very filling. So a bowl of udon can keep you full for a long time. Due to their mild structure, udon noodles digest easily and don’t cause a feeling of heaviness. 

So, even though udon and soba noodles share some features, the udon vs soba noodles battle will never be over.
