If you equate the word soba with buckwheat, the name yakisoba can be misleading and confusing. In Japan, traditional yakisoba noodles are not gluten-free.
Do you have celiac disease, a gluten sensitivity, or follow a gluten-free diet? I wrote this guide to help you enjoy a gluten-free version of yakisoba in your kitchen at home.

Note: I am not a doctor, nutritionist, or health expert. This is only a general informational guide to help point you in the right direction. If you have serious concerns about gluten or gluten-cross contamination, please consult a trusted healthcare professional before eating or cooking yakisoba for the first time.
Does yakisoba have wheat?
Yes, yakisoba noodles contain wheat. Unlike traditional soba noodles made with buckwheat, yakisoba is made with Chinese-style wheat noodles.
Personally, I can understand how this causes some confusion for foreign guests visiting Japan. Let me clear up the confusion so you don't mix them up like I did when I first moved here.
In the olden days, all noodles in Japan were referred to as 'soba'. It's comparable to how we use the word 'pasta' in English. Pasta is an umbrella term to name all sorts of different kinds of noodles: chickpea pasta, lentil pasta, green peas pasta. None of these pastas contain wheat flour just like yakisoba doesn't contain buckwheat flour.
Does that make sense?
I'll give you an example to make it more clear. In Japan, you'll find ramen shops with the sign out front saying chuuka-soba (中華そば) instead of ramen (ラーメン). Chuuka is a Japanese word meaning Chinese. Chuuka soba is translated as Chinese-style noodles, NOT Chinese-style buckwheat noodles. Chuuka soba is the old name for ramen in Japan. Get it now?
The noodles used to make yakisoba actually have a texture and color more similar to ramen noodles.
Technically speaking, yakisoba is made with mushi chuuka men (蒸し中華麺), steamed Chinese noodles. These noodles are made from wheat flour, kansui, and water.

What is yakisoba?
Yakisoba is a popular Japanese dish that has roots in Chinese chow mein. Essentially, yakisoba is Japanese-style stir-fried noodles, typically made with meat or seafood and vegetables like cabbage. Living in Japan over the years, I know yakisoba as a standard street food at matsuri and from school festivals. It's typically cooked in large batches on a big hot griddle, in a wok, or fry pan.
Yakisoba is cheap and filling, which is why it became in Japan popular post-World War II. Nowadays, for Japanese people, yakisoba is kind of like a 'mac n' cheese comfort food. It's an easy-to-make lunch that will feed the whole family on a Saturday afternoon. Everyone is happy, minus you, if you have a gluten intolerance.
The difference between yakisoba and soba
Yakisoba
Despite the similar-sounding names, these two noodle dishes are made with very different kinds of noodles.
It's considered a street food, similar to okonomiyaki and takoyaki, which both have similar toppings to yakisoba. Yakisoba is often on the menu at okonomiyaki restaurants in Tokyo.
Yakisoba noodles are comparable to ramen noodles, which are made with wheat flour. Yaki, in this context, means stir fry. Vegetables, meat, or seafood are added directly to the stir fry.
It's typically garnished with beni shoga (red pickled ginger), katsuo bushi (bonito flakes), aonori or nori dried seaweed, finely chopped green onions, and sometimes mayonnaise. Sometimes it gets topped with a sunny-side cooked egg.
Soba
Soba is traditional Japanese noodles. The noodles tend to be grey in color and have a subtle, nutty flavor. Typically, soba noodles are made with a mix of buckwheat flour and wheat flour. 8o% buckwheat/ 20% wheat flour is a common ratio for making soba noodles.
There are noodles made with 100% buckwheat flour. In Japanese, soba made with only buckwheat flour is called juwari soba.
In the summer, soba is typically eaten cold with a dipping sauce called tsuyu and garnishes like dried nori seaweed, finely chopped green onions, and wasabi paste.
Especially in winter, soba can also be served in a hot broth. At a soba restaurant, you can choose how to top your soba. Some of the standard choices on the menu are tempura or kaki-age, onsen tamago or raw egg, sansai mountain vegetables, or abura-age fried tofu pockets.
Each will have a different name in Japanese based on the topping.

Are soba noodles gluten-free?
No, soba noodles are usually not gluten-free either, with one exception. Having “wheat” in the name buckwheat noodles is misleading.
Buckwheat flour is gluten-free, on its own. But it's very important to know that most packaged soba noodles also contain at least some percentage of wheat flour.
However, there are some soba noodles made with 100% buckwheat flour. In Japanese, 100% buckwheat soba noodles are called juwari soba (十割そば). These can be found at most supermarkets in Tokyo. But from my experience, they aren't labeled as certified gluten-free.
Note of caution: the buckwheat in soba causes an allergic reaction in some people.
