Popular Shaved Ice Shop 'Himitsudo' and Koiwai Dairy Collaborate for the First Time. Limited Edition Shaved Ice Using 'Koiwai Nama Nyu 100% Yogurt' to be Sold from July 1 (Wed)

Koiwai Dairy Co., Ltd. (Headquarters: Nakano-ku, Tokyo; President: Hiroki Matsuzaki) and popular shaved ice shop Himitsudo (Headquarters: Taito-ku, Tokyo; Representative Director: Koji Morishin) will hold their first collaboration, driven by their shared desire to "deliver the original taste of ingredients." Two original shaved ice flavors using "Koiwai Nama Nyu 100% Yogurt" will be available for a limited time from July 1 (Wed), 2026, to August 24 (Mon), 2026, at the Himitsudo Yokohama Bay Quarter store.

Himitsudo, which has been drawing crowds for over 15 years in Yanaka, Tokyo, and is loved as a "catalyst for the shaved ice boom," creates its own fruit syrups using only carefully selected fruits and a little sugar. These syrups are so effective at bringing out the original flavor of the fruit that they are described as "more strawberry than eating strawberries." Meanwhile, Koiwai Dairy, which celebrated its 50th anniversary in June 2026, has continued to create products that leverage the appeal of their ingredients, valuing "manufacturing that can explain the reason for its deliciousness."

This collaboration combines Himitsudo's signature fruit syrups, made with only fruit and a little sugar without any water, with "Koiwai Nama Nyu 100% Yogurt," made solely from raw milk. By merging the ingredient-focused approaches each has cultivated over many years, a special shaved ice for this summer has been created, harmonizing the freshness of the fruit with the deliciousness of the dairy.

For Koiwai Dairy, celebrating its 50th anniversary, this project is not just about delivering products but also about providing a new way for customers to experience Koiwai's deliciousness. By enjoying "Koiwai Nama Nyu 100% Yogurt," loved by many customers for years, in a unique Himitsudo creation, we offer a new encounter with deliciousness.
