New Concept 'Tadokoro Tan Tan Men' to Open in Shinjuku West Exit on June 20, 2026 — A New Style of Tan Tan Noodles Born from Over 20 Years of Miso Expertise and Rich Sesame Flavor

Tentative International Co., Ltd. (Headquarters: Mihama-ku, Chiba City; President & CEO: Fumayuki Tadokoro), which operates over 200 miso ramen specialty stores 'Menba Tadokoro Shoten' domestically and internationally, will open 'Tadokoro Tan Tan Men Shinjuku Nishiguchi Store' — a miso-based tan tan noodle specialty store — on Saturday, June 20, 2026, in Shinjuku-ku, Tokyo.

This store is a new concept that leverages the long-accumulated expertise in miso production and soup development cultivated by 'Menba Tadokoro Shoten'.

By combining the essential richness of sesame in tan tan noodles with the unique umami of Tadokoro's miso, the store achieves a deeply layered flavor profile.

Offering a wide range from smooth, white sesame-based bowls to spicy, numbing varieties featuring Sichuan pepper, it is a miso tan tan noodle specialty store where spiciness can be selected on a five-level scale from 1 to 5.

Three Key Features of 'Tadokoro Tan Tan Men'

① Soup Designed to Maximize Sesame Richness

Spiciness is not the only star.

Using highly aromatic sesame and a proprietary soup design, the natural fragrance and richness of sesame are fully extracted, creating a satisfying flavor that remains enjoyable until the last bite.

② Spiciness Levels for Everyone to Enjoy

While a tan tan noodle specialty store, it does not solely focus on spiciness.

The signature 'White Sesame Tan Tan Noodles' offer a smooth taste highlighting sesame richness, while still delivering the characteristic spice of tan tan noodles. Customers can choose from five spiciness levels (1 to 5; levels 1–3 are free, level 4 adds ¥50, level 5 adds ¥100), allowing spice lovers and those who prefer a mild kick alike to enjoy their ideal bowl.

③ Tadokoro's Unique 'Miso DNA'

Leveraging years of expertise in miso ramen development, the umami of miso is used as a secret ingredient to enhance the flavor of sesame.

Despite being tan tan noodles, each bowl carries the distinctive character of Tadokoro Shoten.
