Located just steps from Ginza, Tokyo’s world-famous shopping and entertainment district, Grandhammer has been steadily gaining attention since its opening in November 2024.
The nine-floor complex offers a new way to experience Japanese food and culture, combining dining, entertainment, and art under one roof. With its 24-hour yokocho-style food alleys, live performances, and cultural attractions such as the Geisha salon Benitsuya and Ama Castle (Amajoh), Grandhammer has become a rising destination for both Tokyo locals and international visitors eager to discover Japan’s authentic yet playful side.

Grandhammer redefines Tokyo’s nightlife and dining scene through its concept of “Food, Entertainment, and Culture.” Each of its nine floors presents a distinct atmosphere — from the lively energy of street-food alleys to refined cultural performances — creating a space where traditional and modern Japan coexist seamlessly. The building’s immersive design and experiential approach make it a hub for travelers seeking to enjoy the depth and diversity of Tokyo in a single location.
