About LE SSERAFIM Support Ads (Member Birthday Quick Reference)
LE SSERAFIM is a five-member K-Pop girl group launched by HYBE group's SOURCE MUSIC. Since their debut in May 2022, a culture of celebrating members' birthdays with support ads and "saengil" (birthday) ads has spread among many FEARNOT (the name for their fans) in Japan.
| Member Name | Birthday | Origin |
|---|---|---|
| Kim Chae-won (Chaewon) | August 1 | Korea |
| Miyawaki Sakura (Sakura) | March 19 | Japan |
| Huh Yun-jin (Yunjin) | October 8 | Korea |
| Nakamura Kazuha (Kazuha) | August 9 | Japan |
| Hong Eun-chae (Eunchae) | November 10 | Korea |
Starting preparations 2 to 4 weeks before a birthday allows you to comfortably set the display date. Especially in August, when Chaewon (August 1) and Kazuha (August 9) have birthdays close together, early application is recommended.
Checking SOURCE MUSIC's Guidelines
Before placing a support ad, it is important to check the fan activity guidelines of their agency, SOURCE MUSIC.
- Types of images that can be used (official photos, social media images, self-made illustrations)

Popular Media and Costs for FEARNOT (LE SSERAFIM Fans)
Digital Signage (Most Recommended)
With a short lead time, some cases allow for placement in as little as one week. Costs can start from around 30,000 yen, making it accessible even for individuals.
Outdoor Vision / Large LED Vision
Large visions in bustling areas like Shibuya and Shinjuku have high visibility and are visually appealing for photos, making them effective for spreading on social media. Costs range from tens of thousands to hundreds of thousands of yen.
Ad Truck
Truck advertising that circulates around live/concert venues. By placing these ads to coincide with LE SSERAFIM's tour dates, they are more likely to be seen by attending FEARNOT. Costs can be shared through crowdfunding (from 500 yen per share).
