Two New Authentic Burgers with Japanese Flavors: Yuzu Kosho and Fresh Shichimi, Arriving Just in Time for the Rainy Season

Freshness Inc. (President: Kentaro Saito / Headquarters: Nishi-ku, Yokohama, Kanagawa Prefecture), a member of the Colowide Group, will launch two limited-edition burgers, the "Yuzu Kosho Aroma: Teriyaki Burger with Aromatic Vegetables" and the "Fresh Shichimi Aroma: Lotus Root and Pumpkin Burger with Black Vinegar Sauce," at its hamburger chain "Freshness Burger" from Wednesday, June 10, 2026.

Two New Authentic Burgers with Generous Vegetables and Layered Japanese Flavors

This time, to coincide with the rainy season, the "Aromatic Adult Japanese Burger" will be available for a limited time, aiming for a flavor that lightens the mood. When you take a bite, the aroma of spices gently spreads, and the rich flavor stimulates your appetite.

The "Yuzu Kosho Aroma: Teriyaki Burger with Aromatic Vegetables" features deep-fried eggplant and plenty of aromatic vegetables such as green onions, red-stemmed radish sprouts, and shredded ginger. The patty is coated with a sweet and savory teriyaki sauce with a hint of soy sauce koji, bringing out richness and umami. The zesty and refreshing spiciness of the yuzu kosho mayonnaise tightens the overall flavor, creating a sophisticated, adult taste.

The other burger, the "Fresh Shichimi Aroma: Lotus Root and Pumpkin Burger with Black Vinegar Sauce," is characterized by the different textures of lotus root and pumpkin. Crispy lotus root and sweet, fluffy pumpkin are combined with a black vinegar sauce that has an exquisite balance of sweetness and acidity. A spicy fresh shichimi mayonnaise, based on Shinshu miso and accented with green chili pepper, yuzu, and sansho pepper, adds an aromatic and spicy kick, further enhancing the richness and flavor. The taste woven from Japanese ingredients and spices gently accompanies your rainy season moments. Please enjoy.
