The new year is a big family event in Japan, and we have a long-standing tradition of eating a bowl of hot soba noodles at the end of the year, which is called Toshikoshi soba. The long and thin buckwheat noodles represent a healthy, long life in Japanese culture. People believe eating these noodles on New Year’s Eve helps leave behind any bad luck from the previous year and brings good fortune and health to the family in the coming year.

I’ll walk you through the ingredients and step-by-step instructions. I hope you enjoy it!

Soba Noodles

Soba noodles are traditional Japanese noodles made by kneading buckwheat flour with water, rolling it thinly, and cutting it into slender strips. They can be enjoyed either cold with dipping sauce or served in a hot soup.

You’ll need the following ingredients to make this Toshikoshi Soba:

Toshikoshi soba ingredients list.
  • Soba noodles – Dried, fresh, or frozen soba noodles are available at grocery stores. I use fresh soba noodles in this recipe.
  • Egg (make onsen tamago), kamaboko fish cakes, tenkasu (crispy tempura flakes), wakame seaweed, and scallions (green onions) for the toppings. To explore the variations, check out the topping section and find more options!
  • Dashi, salt, mirin, and soy sauce for dashi-based broth. Dashi stock is the key ingredient bringing rich umami to Japanese cooking (find more in What is dashi). It’s typically made from bonito flakes, but I use store-bought kombu dashi powder in this recipe. If you like to make homemade noodle soup from scratch, try this Mentsuyu recipe!

Recipe Tips

  • Adjusting Soup Seasoning: If your noodle soup is too salty, you can balance it by diluting it with water. Conversely, if it’s too mild, add more mentsuyu to enhance the flavor.
  • Soba noodles typically take a couple of minutes to cook frozen noodles and around 10 minutes or more for dried or fresh noodles. The cooking time can vary depending on the type and brand of soba noodles, so please follow the package directions.
  • Stir the soba noodles with chopsticks to separate them while cooking.
