When Urban Infrastructure Becomes Media

Recent Trends in Pillar Advertising

In Tokyo train stations, it has become common to see pillars wrapped in character designs, and these sights often attract attention on social media. As shown in the example below.

The tweet by the ちいかわパーク【公式】 (@chiikawa_parkjp) account shows that huge plush figures of the “ちいかわ” characters (like Chiikawa, Hachiware, Usagi, etc.) were put on display at Ikebukuro station for a limited time to celebrate the opening of the ちいかわパーク (Chiikawa park) attraction in Tokyo

Pillars lining the passageways are wrapped with characters, and passersby frequently stop to take photos in front of them. Rather than stopping to view the advertisement itself, it seems that taking a photo with the location as a backdrop has become the main purpose.

These ads take a slightly different form from traditional posters. Instead of being placed on wall-mounted ad panels, the pillars and passageways themselves are used as part of the visual presentation. As a result, the advertisements are no longer flat images but are integrated three-dimensionally into the space.

At first glance, this phenomenon may appear to be a creative example of outdoor advertising. But on closer inspection, it also signals a shift in the relationship between urban spaces and advertising.

Why Use Pillar Advertising?

Advertising that utilizes pillars or passageways functions not just as visual media but as places where people stop, experience, and take photos.

Photos posted on social media reveal the roles these ads play:

  • They attract people to the location.
  • They give people a reason to stop and take photos.
  • Social media sharing extends the advertisement’s reach.
A new form of advertising, which encourages people to take pictures with it.

In other words, advertisements are evolving from “information media” into experiential destinations.


Japan’s Unique Advertising Culture

The success of these ads is closely linked to the cultural context of Japanese urban and station spaces.

  • Stations are crowded hubs
    Many people pass through ticket gates, underground passages, and platforms on a daily basis.
  • Stations offer abundant advertising surfaces
    Pillars, walls, and passageways provide many opportunities for displaying ads.
  • A strong photo-taking culture exists
    Capturing photos is often considered part of the experience at events or exhibitions, and sharing on social media is common.
  • Character IP is widely accepted
    Characters can appear naturally in public and transportation spaces without seeming out of place.

These conditions combine to make pillar advertising particularly well-suited to function as experiential media.


Understanding Pillar Advertising as Experiential Media

Looking at pillar ads in this context, it’s clear they are not just advertisements—they are places designed for photography.

  • People stop by not just to view the ad but to take pictures.
  • Sharing photos on social media expands the ad experience.
  • The advertisement itself becomes part of the urban experience.

In other words, pillars and passageways in urban spaces are shifting from information delivery mediums to stages for urban experiences.


How Pillar Advertising Reflects Changes in Urban Advertising

Pillar advertising highlights characteristics that differ from traditional outdoor ads:

  • Not just meant to be seen
    People stop to take photos, not just glance at the ad.
  • Functions as part of the urban experience
    Ads are no longer simply informational—they become stages that create experiences within the city.
  • Effectiveness is amplified by social media
    Photos taken and shared online extend the advertising experience.
  • Supported by Japan’s cultural context
    The structure of station spaces, the photography culture, and acceptance of character IP all help make these experiential ads possible.

In this way, pillar advertising is attracting attention as a new form that transforms the relationship between urban spaces and advertising from visual media to experiential media.
