How to Place an Ad for Your Favorite Idol/Character in Koenji [2026 Edition]: Costs, Media, and Application Procedures

If You Want to Place a Support Advertisement in Koenji

Koenji is home to many unique live houses such as UFO CLUB, KOENJI HIGH, and JIROKICHI. An increasing number of fans wish to place support advertisements near the venue to coincide with their favorite artist's live performance. This article will sequentially explain the types of advertising media available in the Koenji area, their approximate costs, and how individuals can easily apply for them.

Advertising Media Available for Support Ads in Koenji

Digital Signage (Station Vision)

Digital signage is installed within JR Koenji Station. Since video advertisements are displayed, it is a medium that easily catches the attention of commuters and students. The estimated cost is around several tens of thousands of yen (production costs separate), and by placing the ad starting the week before the live performance, you can convey the presence of your favorite artist to fans heading to the venue.

Ad Trucks

Ad trucks are mobile advertisements with large digital screens that drive through the streets of Koenji. By having them drive through areas where live houses such as UFO CLUB and KOENJI HIGH are concentrated, you can directly deliver your message to fans queuing before and after the live performances. Since they can be arranged for as short as one day, it is possible to run ads to coincide with birthday celebrations or anniversary lives.

Station Posters / Station-mounted Advertisements

JR Koenji Station also has spaces for station-mounted posters and signboards. These paper-based media have a strong presence, and placement near the ticket gates exposes them to many commuters. However, it may take several weeks to a month from application to placement.

Reasons Why Support Advertisements Are Gaining Attention in Koenji

Koenji is known as the center of Tokyo's subculture, with numerous live events held every weekend, primarily featuring indie bands and the underground scene. In recent years, not only fans of Japanese artists but also K-Pop artists are increasingly holding events around Koenji, and the desire to use support advertisements as "sen-il" (birthday celebration) ads is spreading within fan communities.

How to Place a Support Advertisement

Step 1: Determine Purpose and Budget

First, clarify "when, for whom, and what message you want to convey." The timing and location of placement will vary depending on whether it's for a birthday celebration or to support a live tour. For individuals, a budget of around 30,000 yen is a guideline. For larger advertisements using crowdfunding among fans, it's easier to plan if you anticipate a higher amount.

Step 2: Choose the Media

If you want to stand out only on the day of the live performance, an ad truck is suitable. If you want to raise widespread awareness starting a week in advance, digital signage is more appropriate.

Step 3: Apply

Once the media is decided, apply for the service. You will need the visual (image/video data) you want to display and your desired display dates. Also, confirm the agency's guidelines in advance.

Step 4: Create and Submit Visuals

Prepare data in the size and format specified by each media. Once submission is complete, all that's left is to wait for the display date.
