WHAT MUSEUM, operated by Warehouse TERRADA, is a unique museum that only a warehouse company could create—transforming warehouse space into a place for encountering contemporary art and architecture. The name of WHAT (WAREHOUSE OF ART TERRADA) implies the cultural value which is gleaming quietly in the warehouse, and the museum exhibits two- and three-dimensional works as well as architectural models, photographs, films, literature and installations. By showcasing artworks entrusted to Warehouse TERRADA by collectors and artists, the museum bridges artwork storage, exhibition, and engagement. Moreover, as a hub of the international art district, Tennoz, Tokyo, it serves as a nucleus for the local art community, bringing art and culture from the warehouse space to the world.

The museum stores more than 600 architectural models entrusted to us by architects and design firms, of which some are exhibited. Visitors who purchase a combination ticket for the WHAT MUSEUM exhibition will have limited access to see the models in the storage, which are usually not open to the public.

The MUSEUM SHOP offers a selection of original WHAT MUSEUM goods, as well as exhibition-related items and products available exclusively here. You will also find architecture and art books, architecture-related goods, and thoughtfully designed lifestyle items—perfect for gifts and souvenirs from Tokyo and Japan.

From October to December 2026, the MUSEUM SHOP will be specially located inside ARCHI-DEPOT.
During this period, the shop is open exclusively to visitors with admission to ARCHI-DEPOT. Whether you are looking for a special gift, a memento of your visit, or a unique souvenir from Tokyo and Japan, we invite you to stop by the shop.
