    On New Year’s Eve, or Ōmisoka (大晦日), it is a custom for Japanese to reflect on the past year and usher in the coming year, all while enjoying a bowl of hot soba noodles, called Toshikoshi Soba (年越し蕎麦), or year-crossing noodle. What better way to cross over a symbolic bridge than slurping up soba noodles!

    What is Toshikoshi Soba (New Year’s Eve Noodles)?

    The New Year in Japan is about beginning with a fresh, clean slate. That’s the essence of Toshikoshi Soba – starting out simple with a hot soba noodle dish that is healthy and easy to make, and just happens to be a bowl full of symbolism. More on that later.

    The soba noodle dish served on New Year’s Eve is usually in its simplest form – buckwheat soba noodles served in a hot dashi broth with finely chopped scallions. But the basic tradition of Toshikoshi Soba can be taken to the next level by adding in tempura, fish cakes, or raw egg. I believe the New Year should also start out deliciously!

    The Toshikoshi Soba recipe I am sharing today is featured on the popular Japanese TV drama called “Shinya Shokudo (深夜食堂)” or “Midnight Diner: Tokyo Stories” on Netflix.

    Midnight Diner features dishes that are more representative of Japanese home-cooked recipes that you might not have seen in your local Japanese restaurants. “New Year’s Eve Noodles” episode is Season 1, Episode 10 on Netflix.

    History & Culture of Eating Soba Noodles on New Year’s Eve

    The custom and its name differ by region in Japan, but the tradition of eating soba noodles on New Year’s Eve started as early as the 13th or 14th century. However, not until the more recent Edo Period – when the common class developed customary religious and superstitious rituals – did Toshikoshi Soba become more established as an annual tradition on New Year’s Eve for most Japanese people.

    With the hope of good fortune in each bowl, it’s easy to imagine the custom being adopted quickly from family to family, slurping in the symbolism of soba noodles:   

    • To enjoy a fulfilling, peaceful life with every slurp of the long soba noodles.
    • To break free from the past like the soba noodle so easily breaks with each bite.
    • To gather strength and resilience like the tough buckwheat crop.
    • To grow your fortune just as buckwheat flour was once used by goldsmiths to gather up leftover gold dust.

    Superstitious or not, enjoying Toshikoshi Soba has become one of the most enduring traditions observed by the Japanese people in the New Year.

    Make Good Dashi for Toshikoshi Soba

    For a simple noodle soup dish, a good tasty broth is elemental. After all, you want to taste the broth that’s so good that you want to drink up all the soup.

    This dashi based soup broth is light, yet savory and umami-rich from all the essence from kombu and katsuobushi. Unlike chicken or vegetable stock, Japanese soup broth is fast and simple to make. I wouldn’t recommend taking any short cuts like using dashi powder unless you have absolutely no choice. The difference it makes is tremendous.

    Vegan/Vegetarian Soba Noodle Soup

    To make a vegan or vegetarian-friendly Toshikoshi Soba, it is as simple as switching out some ingredients just as below:

    1. Skip katsuobushi (dried bonito flakes) and make Kombu Dashi with just kombu.
    2. Skip kamaboko (fish cake) and add tofu or any other vegetarian/vegan-friendly toppings.

    Too Busy? Here’s the Shortcut Soba Noodle Soup Broth

    You can purchase a bottle of soup base for noodles called Mentsuyu or Tsuyu (つゆ) at a Japanese/Asian grocery store. It looks like this.

    Mentsuyu / Tsuyu (Japanese Noodle Soup Base) | Easy Japanese Recipes at JustOneCookbook.com

    To make noodle soup, all you need to do is to dilute the Tsuyu with water.

    Mentsuyu / Tsuyu (Japanese Noodle Soup Base) | Easy Japanese Recipes at JustOneCookbook.com

    Each brand has different instructions for diluting the Metsuyu. Find the usage guide on the bottle that looks like this.

    The Ratio of Tsuyu to Water

    • Dipping sauce for cold noodles – “Tsuketsuyu” – 1 : 3
    • Hot noodle soup – “Kaketsuyu” – 1 : 6-8
    • Donburi dishes or Tentsuyu – 1 : 3-4
    • Oden or Nabemono (hot pot) – 1 : 8-10
    • Nimono (simmered food) – 1 : 4-6

    For this recipe, hot noodle soup (Serves 2)

    • Hot noodle soup – 1/4 cup Mentsuyu + 2 cups water (1:8 ratio) + I usually add a splash of mirin.

    All you need to do is to heat up the broth and boil soba noodles. Add your favorite toppings and enjoy!

    Yoi Otoshi O (Have a Great Year Ahead!) 良いお年を!

    Ingredients
    Toppings
    Instructions
    1. Gather all the ingredients. [Optional] Soak the kombu in water overnight. If you don’t have time, start soaking the kombu as soon as you can. Bring a big pot of water to a boil for soba noodles.

    To Make Homemade Soup Broth
    1. Add the kombu and kombu water (kombu dashi) in a medium saucepan. Slowly bring it to a boil over medium-low heat (so kombu dashi will be more flavorful). When almost boiling, discard the kombu (you can make Furikake rice seasoning with the leftover kombu).

    2. Add the katsuobushi and simmer for 30 seconds. Then turn off the heat and let katsuobushi sink to the bottom of the saucepan. Let Katsuobushi steep for about 10 minutes (meanwhile, you can prepare toppings).

    3. Drain and reserve the dashi in the measuring cup (or bowl) and discard the katsuobushi (you can make furikake rice seasoning with the leftover katsuobushi). Put the dashi back in the saucepan.
