The archive is comprehensive materials on architecture and urban design projects engaged in by the OTAKA Architectural Design Office (from 1962 to 2010). In addition to the architectural drawings in general (about 35,000 items), the collection also includes many reports on urban design and public works that OTAKA was involved in (about 1,000 items). Not only original drawings of the completion of constructions, but also materials such as booklets of blueprints prepared in the design process, reduced editions of drawings of the completion of constructions, and photograph albums are neatly sorted.
