Soba noodles consist of buckwheat and wheat flour, which have a slightly sweet and nutty flavor with a firm texture. The Japanese eat these buckwheat noodles year-round, both hot and chilled.
Soba noodles (蕎麦・そば) are a type of Japanese noodle made from buckwheat flour or a combination of buckwheat and wheat flour. They are available fresh or dried. Soba shops with noodles made in-house are a real treat as the dough is highly brittle and difficult to knead, thus requiring mastery of the craft. High in nutrition, it’s a specialty that you won’t want to miss when you visit Japan.

What Are Soba Noodles
Soba noodles are long buckwheat and wheat flour noodles. It has a light or dark grayish brown color.
Traditionally, soba consists of buckwheat and water. Adding wheat flour acts as a binder to make it easier to form the dough. Besides buckwheat and wheat flour, there are noodles with additions such as matcha, ume plum, and yam, for color, flavor, and aroma.
The Japanese eat them chilled with a dipping sauce or in a hot dashi broth. While some non-Japanese interpretations call for a loaded bowl with veggies, tofu, and protein or eaten as a noodle salad, with quality noodles, it’s best served simply for the flavors to shine through.

Origin Of Soba
Soba supposedly originated in China and was brought to Japan toward the end of the Jomon period (10,000 to 300 BC). While there are several theories of the origin of soba, soba was first eaten as boiled dumplings called soba-gaki (蕎麦がき). You can still find soba-gaki on the menu of some soba restaurants.
It wasn’t until the Edo period (1603-1867) that soba became the thin, long noodles we know today. Soba was popular street food as it could be prepared and eaten quickly.
Soba Noodles On New Year’s Eve
On New Year’s Eve, or Ōmisoka (大晦日), it is custom for the Japanese to eat soba. Called Toshikoshi Soba (年越し蕎麦, “year-crossing noodles”), it’s eaten to usher in the coming year. The thin, long soba represents longevity and symbolizes strength and resilience like the tough buckwheat crop. The dish is usually served in its simplest form, in a hot dashi broth with finely chopped green onion. Nowadays, soba noodles are also enjoyed with tempura, fish cakes, or poached egg.
Famous Regional Soba – Nagano Prefecture
Regions particularly well-known for its premium soba is Nagano Prefecture. It’s an area where 80% of the land is mountainous, a pristine environment for growing buckwheat but not rice. Surrounded by highlands with volcanic ash soil and fresh, clean water, Nagano also has very distinctive temperatures that are well-suited for soba production. Togakushi (戸隠) and Kurohime (黒姫) are just two of the more famous soba production centers located in the prefecture. You can even find local shops and facilities offering soba-uchi (蕎麦打ち, making soba by hand).

What Does It Taste
Soba noodles have an earthy and deep nutty flavor from the buckwheat. You’ll notice the difference immediately if you compare the taste to udon, wheat flour noodles. A higher percentage of buckwheat results in a more aromatic and nutty flavor, but the noodles are harder and firm.
How To Use
To cook, bring a large pot of water to a boil. Unlike pasta, there’s no need for salt. Add soba to the boiling pot in a circular motion, separating the noodles from each other. Cook the noodles for 4-5 minutes or according to the package instructions (each brand is slightly different). Stir the noodles once in a while, so they don’t stick. Cook until tender.
Once cooked, quickly drain the noodles and rinse under running cold water to remove the starch and prevent further cooking. Drain the water completely before you serve it cold or hot.
