The bond between IZ*ONE and WONCE remains strong

On April 29, 2021, IZ*ONE concluded their approximately two-and-a-half-year activities. However, the feelings of WONCE have not faded.

Even after their disbandment, Miyawaki Sakura is active as LE SSERAFIM, Jang Wonyoung and An Yujin as IVE, and Jo Yuri and Choi Yena continue to shine as solo artists. Why not express your feelings of "WONCE will always support you" on their birthdays to the members who are fighting on their respective stages?

Fan advertisements are a way to make that love "visible" through digital signage and outdoor billboards in the city.

How to Place a Fan Advertisement with Oshi-Ad | 5 Steps

Even first-timers can relax. All steps from 1 to 5 can be completed online.

  1. Access Oshi-Ad and choose your media
    Open app.oshi-ad.com and select the media you want to use (digital signage, outdoor billboards, etc.). You can narrow down your choices by area, date, and budget.
  2. Decide on ad content and duration
    Set the display dates to coincide with your idol's birthday. Applying about 1-2 weeks before the member's birthday allows for sufficient time.
  3. Prepare creative assets (advertisement materials)
    Prepare an image combining photos of the member and a birthday message. Even if you're not good at design, you can use Oshi-Ad's templates. Agency guideline checks are also done at this stage.
  4. Payment/Crowdfunding setup
    Choose whether to pay the full amount individually or use the crowdfunding feature to collect support from fellow fans. Crowdfunding can be set from 500 yen per share. With a 10% fee, almost all collected funds can be allocated to advertising costs.
  5. Display and receive proof
    After display, you will receive a proof photo. Share it on social media to spread your love for the member.

How to Share Costs with Fellow WONCE Fans via Crowdfunding

"It's difficult to cover the costs alone." That's when Oshi-Ad's crowdfunding feature comes in handy. By reaching out on Twitter and fan communities, you can realize a big fan advertisement with the collective power of all WONCE.
