- Making 100% buckwheat noodles more accessible. New brand "Jyuwari Soba Tamotsu" born in Yokohama's Kohoku Minamo

"Tamotsu" is a new brand created to make "100% buckwheat noodles," which allow you to purely enjoy the original aroma and taste of buckwheat flour, more accessible and enjoyable.

While 100% buckwheat noodles allow you to enjoy the rich aroma and taste of buckwheat, they are often perceived as something to be savored slowly at specialty stores or as being a bit high-class.

At "Tamotsu," while cherishing its authentic taste, we aim to be a 100% buckwheat noodle restaurant that you can visit in various everyday situations, such as during a shopping break, after work, or for a family meal.

This project was initiated from the desire of our management strategy advisor, Takafumi Horie, to "create a truly delicious soba restaurant." Based on the concept of Horie, known as an avid soba lover, we have spent over a year searching for the ideal location and pursuing uncompromising product development.

Chef Shusaku Toba, who resonated with this vision, has now joined us. Our company and Chef Toba have previously collaborated on multiple product developments and new brand developments.

In 2025, we commercialized "sio Milk French" and "Toba Curry Bread" supervised by Chef Toba for our bakery brand "Komugi no Dorei." Furthermore, we have repeatedly undertaken initiatives to deliver "everyday food" from a new perspective, such as launching the new brand "Dashi to Monja" through joint development with Chef Toba.

At "Tamotsu," we will develop a new 100% buckwheat noodle brand that is authentic yet easy to incorporate into daily life, by combining Horie's concept, Chef Toba's sensibility, and our company's accumulated expertise in food brand development.

The store is located on the first floor of the commercial facility "Kohoku Minamo" in Tsuzuki-ku, Yokohama City, Kanagawa Prefecture. It is a location that is easily accessible to a wide range of customers, from local residents to business people and families.

The interior has been finished in a Japanese modern space that evokes the warmth of wood. We value a calm yet accessible atmosphere, like a cafe, where you can enjoy authentic soba. We will offer 100% buckwheat noodles that you'll want to eat every day, delivering a "little bit of luxury" in your daily life.

- Smoothness of thin noodles and chewiness of medium-thick noodles in one bowl. "Roughly cut 100% buckwheat noodles" realized with the latest noodle-making technology

"Tamotsu's" major feature is its unique "roughly cut style."

In a single bowl, we blend the pleasant smoothness of thin noodles with the rich chewiness of medium-thick noodles. Each bite offers a different texture, and along with the exceptional aroma unique to 100% buckwheat noodles, you can enjoy it without getting tired until the end.

100% buckwheat noodles, made solely from buckwheat flour, allow you to directly feel the original flavor of buckwheat. However, they are a delicate dish that requires advanced techniques in kneading and boiling.

"Tamotsu" has introduced the latest noodle-making machines, merging artisan techniques with technology. We have established a system to provide "freshly made and freshly boiled" soba with stable quality.

The signature dishes are "Shinme Mori Soba," which allows you to simply enjoy the aroma and roughly cut texture unique to 100% buckwheat noodles, and "Chicken Seiro" supervised by Chef Toba. "Chicken Seiro supervised by Chef Toba" pairs freshly made and boiled 100% buckwheat noodles with a dipping sauce that brings out the umami of the chicken, creating a flavor where the aroma of soba and the umami of chicken overlap.

In addition, we offer menu items that are easy for everyday dining, such as "Niku Soba Seiro" recommended for those who want a hearty meal, "Aotogarashi to Kujo Negi Tanuki Bukkake Soba" where you can enjoy the refreshing spiciness of green chili peppers and the aroma of Kujo leeks, and the "Jyuwari Soba Set with Mini Jyu" which combines Mori Soba with a mini rice bowl.

Authentic 100% buckwheat noodles, made smarter and more accessible. While cherishing the rich aroma and pleasant smoothness of soba, we deliver a bowl you'll want to eat every day.

- "Komugino Co., Ltd.", a comprehensive production company that expands the possibilities of food

Komugino Co., Ltd. is a comprehensive food production company that operates under the slogan "Let's connect with food that excites the heart," and is involved in the development, franchise expansion, and production of food brands.

In addition to the nationwide expansion of its main brands, the company continues to expand the possibilities of food through diversified businesses such as collaboration with local companies, overseas expansion, support for the production of restaurant companies, and M&A.

The new brand "Jyuwari Soba Tamotsu," which will open this time, aims to expand its stores nationwide through franchise expansion in the future.

The owner of the first franchise store to commemorate this occasion is Fire Kids Co., Ltd. (Representative Director: Kazuo Sato). Founded in 1995, the company is a specialty store for vintage and antique watches, providing high-quality vintage and antique watches at reasonable prices, and has gained the support of many watch enthusiasts.

The company's corporate concept is "Connecting valuable things to the future." It aims to be a "comprehensive vintage company" that inherits and re-produces and expands Japanese culture and craftsmanship, such as swords and agricultural products, before they are lost, and passes them on to the next generation. Mr. Sato deeply resonates with the philosophy of "Tamotsu," which views 100% buckwheat noodles as one of Japan's cultures that should be preserved and spread, and aims to re-evaluate their value by combining them with modern technology. He volunteered to become the owner of the first franchise store. For our company as well, a new challenge begins here with a strong partner who shares this philosophy.
