Click here for a short video (by Monocle) about Tokyo's nascent "kitchen car", or food truck, scene. (The soundtrack is fun.) Historically, street food stands, or "yatai," have had a questionable reputation in Japan. They proliferated across the country following World War II when times were tough and food was being rationed. But as Tokyo prepared to host the 1964 Olympics, local governments began to clamp down on yatai. They were seen as unhygienic and a place for drunks to hang out. There may have also been a sense of shame around the country's post-war struggles. Whatever the case may be, these new food trucks have -- aided by technology -- changed the way people eat on the street.
