The Unique Collaboration of Coolish and Fuji Soba

A fascinating collaboration has emerged from the blend of Lotte’s popular drinkable ice cream, "Coolish," and the renowned Fuji Soba chain. Launching on February 1, 2026, for a limited time, the new dish named ‘Coolish Whipped Katsu Don’ will be tantalizing taste buds at select Fuji Soba locations: Akasaka, Ikebukuro, and Gotanda. With only 10 servings available daily at each location, this unique dish is priced at 770 yen (tax included).

The creation process of this exclusive dish takes a classic Katsu Don to new heights. Instead of the typical fried pork cutlet bowl, this special version mixes approximately 2 grams of Coolish Whipped Cream directly into the egg used to coat the katsu. After being prepared, the bowl is topped with an additional dollop of Coolish Whipped Cream, bringing a revolutionary twist to the traditional Japanese meal. The end result is a bowl of Katsu Don that not only features the rich flavors of Fuji Soba's signature dashi broth enriched with sweetness but also the novelty of the cold, sweet Coolish Whipped Cream. It's a match that offers a delightful combination of creamy texture and a fusion of hot and cold sensations—a truly unique experience!

The idea for this collaboration isn’t purely business-minded; it was borne from the imagination of Shizurina Arai, an ice cream researcher. "When I thought about it, the egg whites in Katsu Don looked just like ice cream, didn’t they?" Arai’s playful hypothetical became a culinary reality when she envisioned pouring Coolish over the dish. This playful experimentation has led to an extraordinary synergy between sweet and savory, proving to be more than just a creative endeavor but rather a delicious reality.

Insights from the People Behind the Dish

Arai shares her thoughts, saying, "The sweet and savory tastes combined in this unique dish exceed expectations. This bowl is truly crafted with passion!" Meanwhile, Koji Furutaya from Daitang Shōji, the company managing Fuji Soba, added, "This second collaboration between Fuji Soba and Coolish was not just about slapping ice cream onto a dish. Mixing Coolish into the egg elevated the experience and showcased unexplored dimensions of Katsu Don. We believe that everyone, young and old, can enjoy this dish."

Lotte’s Watanabe Kazuya also expressed enthusiasm about this collaboration, highlighting, "This is not just a drink anymore. It opens a new menu possibility! The excellent combination of Katsu Don and Coolish is a must-try!" It’s safe to say that this exciting culinary creation encourages diners to look beyond governmental norms in the best way possible!
