One of the latest trends in Japanese advertising is the sign truck. They started appearing a few years ago, but these days if you go somewhere like Shinjuku or Shibuya, they’re everywhere. The trucks drive around and around in a short route through an area with a lot of people, and often play music as well.
According to the website of an ad agency that specializes in sign trucks, they’ll get seen by 400 people per kilometer, 48,000 people per day, and 1,056,000 people per month. They’re not cheap though, and a small 1-ton truck costs about a million yen ($10,000) per week. The big 40-ton trucks cost more than 2.5 million a week.
