Tsukiji Gin-dako Launches Limited-Time Premium Mentaiko Series 'Yuzu Negi Mentaiko' Featuring Hakata no Aji Yamaya's Aged Spicy Cod Roe, Starting July 18 (Sat)

Hotland Holdings Co., Ltd. (Headquarters: Chuo-ku, Tokyo; President & CEO: Morio Sase), which operates Tsukiji Gin-dako stores domestically and internationally, will launch the premium Mentaiko Series 'Hakata no Aji Yamaya's Yuzu Negi Mentaiko' for a limited time starting July 18, 2026, at all Tsukiji Gin-dako stores nationwide (excluding some locations).

The latest addition to Tsukiji Gin-dako's 'Premium Mentaiko Series' is a collaboration with 'Hakata no Aji Yamaya'! The ever-popular 'Mentaiko Series' has evolved once again this summer.

'Yuzu Negi Mentaiko' uses premium aged spicy cod roe (mentaiko) that has been carefully marinated for 168 hours (7 days) in Yamaya's signature 'Takumi Tare' brine—a recipe preserved since the company's founding—concentrating rich umami into each individual roe grain. This high-quality mentaiko, known for its excellent grain texture and deep, rich flavor, is blended into a specially formulated golden-ratio mentaiko sauce designed to perfectly complement Gin-dako's takoyaki. Topped with crisp, aromatic 'Kujō negi' (Kyoto green onion), 'white sesame seeds', and 'finely chopped nori', the dish also includes a separately packaged 'special yuzu sauce' developed for final seasoning just before eating.

By drizzling the 'special yuzu sauce' over the takoyaki just before consumption, the bright, refreshing acidity and elegant aroma of 'Kito yuzu' from Tokushima Prefecture are instantly released, enhancing the overall flavor profile.

Aged spicy cod roe marinated for 168 hours in the rich 'Takumi Tare'—made with alcohol as the base and no water added.

[Special Mentaiko Sauce Made with Hakata no Aji Yamaya's Aged Spicy Cod Roe!]

The 'special mentaiko sauce' in 'Yuzu Negi Mentaiko' uses Hakata no Aji Yamaya's aged spicy cod roe, matured for 168 hours in the flavorful 'Takumi Tare'.

Premium ingredients aged for 168 hours in 'Takumi Tare'—resulting in glossy, flavorful mentaiko.

The Overwhelming Commitment Behind 'Yuzu Negi Mentaiko'

1. A Golden-Ratio Sauce Featuring Hakata no Aji Yamaya's 168-Hour Aged Mentaiko

We blend mentaiko carefully aged for 168 hours (7 days) using Yamaya's secret salting techniques and seasoning liquid. While preserving the full umami of each roe grain, we've crafted an original blended sauce that perfectly matches the taste of Gin-dako's takoyaki.

2. Kujō Negi That Enhances Texture and Aroma

We use premium Kujō negi for its rich flavor. Each onion is precisely cut at a '2mm width' and '45-degree angle'—optimally severing the fibers to create a tender bite while preserving the crisp, satisfying texture and rich aroma.

3. Separately Packaged 'Special Yuzu Sauce' Featuring Tokushima's Kito Yuzu for Dramatically Enhanced Citrus Flavor

By providing the yuzu sauce separately rather than pre-applied, we lock in the fresh citrus aroma until the very moment of consumption. The burst of refreshing citrus coolness adds an exquisite accent to the savory mentaiko sauce and takoyaki.

Generously topped on hot, freshly cooked takoyaki with the special mentaiko sauce made from Hakata no Aji Yamaya's aged spicy cod roe.

The rich umami spreads throughout your mouth—an absolutely 'premium' taste experience. Don't miss this limited-time offering available only now.

[Recommended Way to Enjoy 'Yuzu Negi Mentaiko']

1. Cut open the takoyaki with chopsticks and slightly open the center.

2. Generously stuff the split takoyaki with toppings.

By filling the split takoyaki with toppings, the harmonious blend of flavors spreads fully in your mouth—an exceptional sensory experience!
