How to Put Out an Advertisement for BTS's RM (Namjoon) [2026] Birthday Saneil Guide
Share
What is a BTS RM (Namjoon) Fan Ad?
BTS RM (Kim Namjoon)'s birthday is September 12th. RM was born on September 12, 1994, completed his military service and was discharged in June 2025. In 2026, BTS released their new album "ARIRANG" as a complete group and embarked on a world tour.
Fan ads (also known as "Saengil ads" or birthday ads) are advertisements placed by fans in public spaces such as streets, train stations, and commercial facilities to celebrate their idol's birthday or anniversary. In Japan, it has become a widespread culture for ARMYs to display visuals of RM on digital signage and outdoor screens every September for his birthday. Since it's possible for individuals to place these ads starting from about 30,000 yen and with a minimum lead time of one week, a single fan can send a congratulatory message in their own name.
Checking HYBE/BigHit Music Guidelines
RM is managed by BigHit Music, an affiliate of HYBE. Before placing a fan ad, please be sure to check BigHit Music's fan activity guidelines.
Key points to generally check include:
- Conditions for using artist photos and video materials (unauthorized use of materials other than those officially provided is generally prohibited)
- Prohibition of expressions that suggest "official" status (phrases implying representation of BTS or BigHit Music are not allowed)
- Prohibition of commercial purposes or revenue-generating activities
- Adherence to prohibited areas and expressions specified by the agency
If you are unsure about checking the guidelines, you can consult with the Oshi-Ad operating team. They provide support for checking agency guidelines.

How to Place a Fan Ad
STEP 1: Determine Objective and Budget
The budget will vary depending on whether you "want to send a congratulatory message personally (from 30,000 yen)" or "have all ARMYs take over a large screen (over 100,000 yen)". For individuals, digital signage starting from 30,000 yen is ideal.
STEP 2: Select Media and Area
If you want to display the ad one week before or after his birthday (September 12th), digital signage is a safe bet, as it can be displayed in as little as one week from application. Large screens and station posters have longer lead times, so it's recommended to prepare 1-2 months before the birthday.
STEP 3: Prepare Creative (Design)
Use images and videos that comply with HYBE/BigHit Music guidelines. If using fan art or officially provided images, check the usage conditions in advance.
STEP 4: Application, Display, and Promotion
Gather the desired media, dates, and creative data, then apply. On the day of display, take photos and videos at the location and post them on social media to further spread awareness within the ARMY community.
