What are NCT 127 Fan Support Ads? (Profiles & Japanese Fan Culture)
NCT 127 is a K-Pop group from South Korea that debuted on July 7, 2016, under SM Entertainment. "127" refers to the longitude of Seoul, and as an NCT unit based in Seoul, they boast global popularity.
As of 2026, the members are Johnny (born February 9, 1995), Taeyong (born October 1, 1995), Yuta (born October 26, 1995), Doyoung (born February 1, 1996), Jaehyun (born January 14, 1997), Jungwoo (born February 19, 1998), and Haechan (born June 6, 2000). Mark left NCT 127 in April 2026 after his exclusive contract with SM Entertainment ended.
Their fan club name is "NCTzen." Representative songs include "Regular," "Simon Says," "Cherry Bomb," "Sticker," and "Highway to Heaven." They have also released Japanese songs and are strengthening their bond with Japanese fans, including holding a world tour in Japan, including at Tokyo Dome, in 2025.
The "saengil (Korean for birthday) ad" culture, which originated in Korea, the home of K-Pop, has also spread to Japan. NCTzens have also established a culture of expressing their love for their idols by placing support ads for birthdays and anniversaries. When ads for NCT 127 members are displayed on large screens in Shibuya and Shinjuku, or on signboards around live venues, they generate a significant response on social media.
Checking SM Entertainment's Guidelines
Before placing a support ad, it's essential to check the agency's guidelines. SM Entertainment has official fan activity guidelines, and several points need to be considered when placing support ads.
- When using official photos/videos of members, pay attention to copyright and portrait rights.
- Ad designs must include the organizer's "group name or individual name" and "contact email address" (as per media company regulations).
- Do not use content that damages the members' honor or image.
- Do not use expressions that could lead to the misunderstanding that the ad is officially recognized or supervised by the agency or official channels.
If you have any questions, it's best to check SM Entertainment's fan club website or official NCT announcements, or consult with the support team of the ad application service. Oshi Ad provides support for checking agency guidelines, so even first-timers can proceed with confidence.
Popular Media and Costs for NCTzen
Digital Signage (Most Recommended)
These are electronic billboards installed in train stations and commercial facilities. Their short lead time, allowing placement in as little as one week, is attractive. Costs start from around 30,000 yen, making them accessible even for individuals to apply, which is why they are particularly popular among NCTzens. They also have a high viral effect on social media and can dynamically display photos and videos of your idol.
Outdoor Vision (Street Large Monitors)
Placing ads on large screens in bustling areas like Shibuya and Shinjuku has a huge impact. They are likely to catch the eye of passersby, and fans are highly satisfied because they can take photos that look great on social media. Costs vary widely depending on the media and duration, but the method of sharing costs through crowdfunding among multiple people is also becoming widespread.
Ad Trucks
Ad trucks driving around live and concert venues have the effect of being seen by all attending fans. Ad trucks playing NCT 127's music as they drive around the venue directly contribute to the excitement on site.
Live Venue Surround Signage
Signage displayed near the venue on the day of the concert creates a sense of unity among other fans. Secondary diffusion can also be expected as attendees post on social media.
Popular Posting Areas in Tokyo and Osaka
Tokyo Area
Shibuya and Harajuku are areas where many K-Pop fans gather. Large screens near the Shibuya Scramble Crossing and signage around Harajuku and Takeshita Street have high social media virality and a rich history of NCTzen postings. Shinjuku has a high volume of foot traffic as a terminal station, and outdoor signage within and around the station is popular. When concerts are held at Tokyo Dome, there is also a lot of posting in the Suidobashi and Korakuen areas.
Osaka Area
In Osaka, outdoor screens around Dotonbori and Shinsaibashi are classic posting spots. The Umeda and Namba areas have heavy foot traffic, allowing the presence of idols to reach passersby who are not fans.
How to Place a Support Ad
Step 1: Determine your objective and budget
Clarify your objective, whether it's to celebrate a birthday or commemorate a live concert. Deciding whether you'll bear the full cost yourself or share expenses with fellow NCTzens through crowdfunding will make the process smoother. For individual placements, a budget of around 30,000 yen is a guide, and for crowdfunding participation, it can start from 500 yen per share.
Step 2: Choose the media and posting period
Decide "when, where, and in what form you want to place the ad." Ideally, start planning about 2 to 4 weeks before the birthday. Since lead times vary by media, apply early by calculating backwards from your desired posting date. Many digital signage options can accommodate requests within about a week, so it's sometimes possible even at the last minute.
Step 3: Create the design and apply
Prepare the images and videos to be used in the advertisement. Each media outlet has specific size and format requirements, so check these in advance. After completing the application, the posting will be decided after coordination and review with the media company.
