D Capital, Inc. (“D Capital”) announces that The Oyatsu Company Ltd. (“Oyatsu Company”) has acquired all shares of the special purpose company that is the wholly owning parent company of Yamayoshi Seika Co., Ltd. (“Yamayoshi Seika”), as of December 26, 2025, welcoming the company into the Oyatsu Company group.
Background and Purpose of the Transaction
The Oyatsu Company, founded in 1948, is one of Japan's leading manufacturers of snack foods. Born from the idea of "eating ramen as a snack," Baby Star Ramen was created in 1959. It has evolved to become one of the most famous snacks in Japan, enjoyed by both children and adults. Under the philosophy of "creating plentiful, and happy, 'snacks' and 'dreams',” The Oyatsu Company continually releases innovative snacks.
Through this acquisition, Oyatsu Company aims to combine the unparalleled uniqueness of its flagship Baby Star brand with the distinctive brand power that Yamayoshi Seika’s “WASABEEF” has established in the potato chip market. By bringing together these two highly original brands, the group seeks to create a truly distinctive and differentiated brand position within the snack food market.
About Yamayoshi Seika
Since its founding in 1953, Yamayoshi Seika has been committed to delivering “delicious” and “fun” experiences to consumers through products inspired by nature’s bounty. Its flagship product, WASABEEF, launched in 1987, has been a long-selling brand for nearly 40 years and continues to enjoy strong customer support.
While adapting to changing times, Yamayoshi Seika remains steadfast in its commitment to universal values such as safety and quality. In close collaboration with producers and distribution partners, the company strives to provide products and services that deliver excitement and delight to all customers. The company has built a robust business foundation centered on WASABEEF brand, supported by a highly reliable supply chain spanning potato sourcing through production and distribution.
Future Outlook
Under its vision of “Unlock Japan,” D Capital seeks to unlock the full potential of Japan’s world-class confectionery industry through a combination of hands-on management support and digital transformation initiatives.
Through this integration, we are confident that by sharing the brands, intellectual property, sales networks, and accumulated expertise of both companies, the group will be able to deliver even more attractive products to both domestic and international consumers.
Together with Oyatsu Company, Yamayoshi Seika, and another D Capital portfolio company, Kabaya Foods, D Capital will continue to fully support efforts to unlock the intrinsic value and untapped potential of Japan’s confectionery industry, driving sustainable growth and long-term enhancement of corporate value.
