How to Put Out a Girls' Generation Ad: 2026 Birthday Guide

What is Girls' Generation Fan Support Advertising?

Girls' Generation (SNSD) is a 9-member girl group under SM Entertainment. Debuting on August 5, 2007, they have garnered passionate fans (SONE) worldwide, including in Japan, with hit songs like "Gee," "Oh!," "Run Devil Run," "The Boys," "I Got a Boy," and "Lion Heart." In Japan, they have released numerous Japanese singles through Universal Music Japan and held many domestic concerts.

Since Jessica's departure in 2014, the remaining eight members have actively pursued solo careers. Taeyeon's (Kim Taeyeon) solo activities, in particular, have attracted significant attention both domestically and internationally, leading to active planning of fan support advertisements for her by fans.

Fan support advertising (Saengil advertising) is a culture where fans pool their money to celebrate their favorite member's birthday or debut anniversary with advertisements in public spaces. Originating in Korea, this culture has become well-established in Japan, with advertisements appearing annually across the country to coincide with Girls' Generation members' birthdays.

Popular Media and Costs for Fans

Girls' Generation SONE fans tend to prioritize both visibility of the posting location and social media appeal when choosing fan support advertising media. The main media types and estimated costs are as follows:

Digital Signage

Digital signage in train stations and commercial facilities is a primary medium, offering short lead times and ease of application for individuals. With Oshi-Ad, you can place an ad starting from approximately 30,000 yen. It supports both video and still images, and in many cases, visuals created by fans can be directly displayed.

Outdoor Vision

Large outdoor visions installed at Shibuya and Shinjuku intersections are popular among fans due to their high social media virality. Media with extensive experience in fan support advertising, such as Unica Vision (Shinjuku) and Studio Alta Vision (Shinjuku), are available. Costs vary depending on the medium and display duration, but typically range from tens of thousands to hundreds of thousands of yen per day.

Ad Trucks

Ad trucks that run around concert and event venues can directly appeal to fans gathered there. They are often planned in conjunction with concerts, and costs can be raised through crowdfunding for group support advertisements.

Popular Posting Areas in Tokyo and Osaka

Here are popular areas for fan support advertisements that are favored by Girls' Generation fans (SONE).

Tokyo Area

• Shibuya: Outdoor visions around the Shibuya scramble crossing attract high attention from both domestic and international audiences, with excellent social media spreading effects. Signage around Shibuya Hikarie and Dogenzaka also has a proven track record.
• Shinjuku: With multiple options like Alta Vision, Unica Vision, and Cross Shinjuku Vision, Shinjuku is a classic area for fan support advertisements as a bustling district where fans gather.
• Harajuku/Omotesando: This area attracts many K-POP fans, making it highly efficient for reaching the target audience.

Osaka Area

• Umeda: As the center of Osaka with high traffic, it is a gathering point for fans and has numerous K-POP-related fan support advertising achievements.
• Namba: Outdoor visions around Dotonbori have a significant impact and are popular as photo and video spots.

How to Place a Fan Support Ad

Here are three steps explaining the process of actually placing a Girls' Generation fan support advertisement.

Step 1: Determine Purpose and Budget

First, decide for whom and when the ad will be placed. Whether it's a birthday celebration, debut anniversary, or support for a concert, the posting date, location, and visual direction will change accordingly. For individual self-placement, the budget can be set flexibly from around 30,000 yen, and for group crowdfunding, it can range up to several hundred thousand yen.

Step 2: Select Media and Posting Area

Choose from digital signage, outdoor vision, or ad truck. If aiming to post around a live venue, timing it with the concert schedule is effective. Signage often has a short lead time, typically around one week, and can accommodate applications right before a birthday.

Step 3: Prepare Design and Apply

Prepare visuals according to the size and format specified by each media and submit the application. In many cases, production is divided among fan communities, and there are also options to use design tools or hire professional designers. The process from application to completion of posting generally takes about 1 to 4 weeks. Since some media require pre-screening, it is recommended to proceed with a comfortable schedule.
