Akihabara is Japan's largest electronics district. Here, there is an electronic component store that attracts hobbyists from all over the country. Resistors, capacitors, circuit boards... The store carries an astonishing 100,000 items across four floors. Every day, 1,000 customers, ranging from professional engineers to hobbyists, visit the store to shop. From musicians building their own effects pedals to high school students dreaming of robot development, and college students unwinding from job hunting by tinkering with electronics—what are their motivations, and which components do they seek?
