Edo kuzumochi, chic, healthy and cute!
An Edo-style snack made into a pop-up Japanese sweet.

Edo Kuzumochi is a brand launched in 2015 by Yamashin Shokusan Corporation, a factory specializing in kuzumochi, to celebrate its 60th anniversary.

KUZUMOCHI is a simple Japanese confectionery that has been eaten in Tokyo for centuries, and we have turned it into a "delicious and cute" Japanese sweet that can be enjoyed by everyone from children to the elderly.

古伊万里に江戸久寿餅
  1. 01. Kuzumochi

    Kuzumochi in Tokyo is written in Chinese characters as "久寿餅," which means "longevity without illness for many years".

  2. 02. Fermentation

    Tokyo's Kuzumochi is a fermented food that is rare in Japanese confectionery. Starch from wheat, from which gluten is removed, is lactobacillus fermented for more than two years, then washed in water for about a week at the factory and steamed to the optimum flavor and acidity. The longer the fermentation period (over 730 days), the finer the starch becomes due to enzymatic decomposition, making it smoother to the palate and giving it a unique texture that is more moist and crispy.

  3. 03. Keep the gut healthy

    Powdered and fine wheat starch is digested without burden in the intestines. It has been reviewed as "the best beauty food" because it is easy to digest and keeps the stomach full. In addition, it has been selected as a Japanese "super food" because the plant-based lactic acid bacteria feed the good bacteria in the intestines and activate the intestinal lining.

  4. 04. Kuromitsu

    The "Kuromitsu Manager" has evolved a recipe that has been used for over 55 years to create a rich and full-bodied Kuromitsu that is even more delicious and pleasing to the palate. It is a gem made by carefully blending several kinds of sugar and simmering it slowly over a long period of time. In December 2028, at the 65th Edogawa Ward Industrial Awards Ceremony, Zenya Umezawa, a.k.a. "Director of Kuromitsu Department," received the Technical Achievement Award.

  5. 05. Kinako

    Exquisite roasting techniques are required to create the aroma of soybean flour that stirs the hearts of people. Our unique deep hot-air roasting method slowly draws out the aroma and sweetness of soybeans over time, and then crushes them into small pieces to create a gentle, melt-in-your-mouth texture.

Drizzle Kuzumochi with molasses and soybean flour and enjoy the nostalgia of downtown Tokyo.

Edo Kuzumochi is naturally fermented for 730 days, has no preservatives, is vegetable-based, and contains no eggs or dairy products. In addition, these are wheat-allergen-free and gluten-free, healthy Japanese confectionery.

I want to bring the freshly made, delicious taste of my grandfather’s cooking to our customers.

山信食産 三代目 代表取締役社長 小山信太郎

My childhood snack was getting fresh (ready-made) Kuzumochi from my grandfather.

It was so delicious that I could eat it every day and never get tired of it. I think my grandfather was happy to see the joy on our brothers’ faces.

Twenty-five years later, when I joined the company, I had my first taste of fresh kuzumochi in a long time. I was surprised at how delicious it reminded me of my childhood. I started a new brand “EDO KUZUMOCHI” because I wanted many people to enjoy it and be happy with it.

We will continue to work hard to offer new tastes and ways of eating the precious “fresh kuzumochi” that can only last for two days after two years of fermentation, so that customers in my hometown of Edogawa Ward and other areas of Tokyo will choose it as their favorite confectionery.

In the future, my grandchildren will enjoy eating Kuzumochi every day, and I intend to develop it into an Edo-Kuzumochi that will bring smiles to the faces of our customers.
