Idea Digital Code

Even if you're not planning on buying anything, it's always fun to browse the fancy gadgets on display at this boutique in Roppongi's Tokyo Midtown shopping mall. The tech-centric offshoot of design store Idea International, Idea Digital Code specialises in audio equipment and home appliances, though even its most humdrum offerings – humidifiers, vacuum cleaners, etc. – look like something out of the future.
