Share
What is a JEON SOMI Fan Advertisement?
JEON SOMI (Jeon So-mi) is a South Korean-Canadian solo artist born on August 9, 1996. Her real name is Somi Douma. She belongs to THE BLACK LABEL (a YG Entertainment-affiliated label) and made her solo debut on June 13, 2019, with her debut song "BIRTHDAY."
Her hit songs include "BIRTHDAY," "What You Waiting For," "DUMB DUMB," "XOXO," and "Fast Forward," all of which are highly popular in Japan. Fan meetings and solo concerts have also been held in Japan, making fan advertisements for Somi's birthday (August 9) or concert anniversaries particularly meaningful for her fans.
Fan advertisements are activities where fans purchase advertising space on digital signage or outdoor billboards at their own expense to express their love and gratitude for their idol in public spaces. The "Saengil (Birthday) Ad" culture, which originated with K-Pop fans in Korea, has also taken root in Japan and can now be frequently seen in major stations and downtown areas across the country.
Checking THE BLACK LABEL's Guidelines
When placing a fan advertisement, it is crucial to always check the guidelines of the artist's agency in advance. We recommend checking the latest guidelines on THE BLACK LABEL's official website or official Japanese social media accounts, or consulting with Oshi-Ad's support team.
- Whether photos other than official provided materials can be used
- Rules for displaying logos and artist names
- Prohibitions on expressions that may be confused with commercial purposes
- Copyright notation when posting on social media
Oshi-Ad also provides support for checking agency guidelines. Even first-time fan advertisers can proceed with peace of mind.

How to Place a Fan Advertisement
Step 1: Determine your goal and budget
First, clarify "who you are targeting and why." The optimal medium and posting area will vary depending on the timing, such as celebrating a birthday (August 9) or commemorating a concert or fan meeting. The budget will also change depending on whether one person is funding it or if multiple people are contributing.
Step 2: Select the medium and posting area
Choose the medium based on your budget and goal. For an easy start, digital signage is highly recommended. It is cost-effective and has a short lead time, allowing you to apply even shortly before a birthday. If you want to create excitement near a concert venue, an ad truck can also be effective.
Step 3: Prepare the design and apply
Create a design with a message, using materials that adhere to the agency's guidelines. At Oshi-Ad, staff will review the design and support agency guidelines after your application, so even first-timers can proceed with confidence. Posting can be done in as little as one week from application.
