Bunkamura is Shibuya's long-running culture complex, known for art exhibitions, film screenings, theatre, and concert programming. It gives the area a calmer cultural counterweight to the shops and street crossings outside.
Check the current programme before going, as the value of a visit depends on what is on. When the galleries and halls are active, it is one of the easier places in west-central Tokyo to fold art or performance into a Shibuya day.
