Atop Mori Tower, this gigantic gallery space sports high ceilings, a broad view and thematic programs that continue to live up to the hype associated with Roppongi Hills. Contemporary exhibitions are beautifully presented and include superstars of the art world from both Japan and abroad. Every three years (including in 2019) the museum stages a showcase of up-and-coming Japanese artists called Roppongi Crossing.
Admission to the museum is shared with Tokyo City View, which wraps itself around the 52nd floor. From this 250m-high vantage point you can see 360-degree views of the seemingly never-ending city. Weather permitting you can also pop out to the external rooftop Sky Deck (additional adult/child ¥500/300; 11am to 8pm) for alfresco views.
