What is Soba?
A Beginner’s Guide to Japanese Soba
Soba is a type of Japanese noodle made mainly from buckwheat flour. Buckwheat is a grain-like seed with a distinctive nutty flavor.
Soba is enjoyed all over Japan, and different regions have their own styles. You may also see different ratios of buckwheat flour and wheat flour, which can change the texture and flavor.
What Does the Soba Percentage Mean?
You may see numbers such as 80% or 100% when looking at soba. These numbers show how much buckwheat flour is used compared with wheat flour.
Hachiwari Soba（八割そば）
Hachiwari means 80%. Hachiwari soba is made with about 80% buckwheat flour and 20% wheat flour. It’s a common style of soba and often has a balanced texture and flavor.
Juwari Soba（十割そば）
Juwari means 100%. Juwari soba is made with 100% buckwheat flour. It usually has a stronger buckwheat flavor and a different texture from soba made with wheat flour.
Why I Love Soba
I prefer cold soba because I like its firm texture. Hot soba is softer, while cold soba keeps more of its texture. For me, that firm and refreshing texture is one of the best things about soba.
Cold or Hot?
Cold Soba
Cold soba is usually served with a separate dipping sauce or a sauce poured directly over the noodles. It’s especially popular during warmer months.
Hot Soba
Hot soba is served in a warm soup. It’s especially comforting in colder weather and is often served with toppings such as tempura, green onion, or spicy chili powder.

Buckwheat itself does not contain gluten, but many soba noodles also contain wheat flour. Soba is not automatically gluten-free. If you need to avoid gluten, check the ingredients and ask the restaurant.
Vegetarian & Vegan
The noodles may be vegetarian or vegan, but the dipping sauce and soup can contain fish-based dashi. Check the ingredients and toppings before ordering.
Buckwheat Allergy
Buckwheat can cause allergic reactions in some people. If you have a buckwheat allergy, always check with the restaurant before ordering.
