Due to popular demand, Tokyo Midtown Design Hub's third annual Prototype exhibition has been extended until Dec. 13. Prototype shows the work of Japanese creators – mostly architects, product designers and furniture designers – with a focus on the creative process and problems of turning an idea into an object. Each display has notes and sketches drawn directly onto the tables by the designers themselves, giving the viewer insight into  their creative process. This makes the show fun for both die-hard design followers and those with only a passing interest. The finished products are beautiful, to be sure, but just as interesting are the scrawled diagrams, and in some cases, the tools used to make the new products on display.

Personal favorites were Teruhiro Yanagihara's polarized candle holder, Naoki Terada's coded imunization kit and Ben Nagaoka's "View Bench" (but we're even bigger fans of what he and Point Design can do to a room, when given the chance).

Admission is free.
