"1,000 Posts by a Personal Brand": The SNS-Driven Collage Culture Born from User Participation

The personal creative brand "nene_hope_heart" has surpassed 1,000 total posts in its user-participatory collage project conducted on social media. In response, the brand is launching a participatory event titled "Kaguya Galaxy Cherry Blossom Viewing Party," further strengthening its commitment as a community-based brand.

■ A Participatory Collage Culture Exceeding 1,000 Posts, Born from a Personal Brand

"nene_hope_heart" is a personal creative brand that plans and sells decorative PET stickers and design paper.

The brand's hashtag project, "#celestialpirates2026," invites users to post their own creations based on a shared theme. As a result, the total number of posts has exceeded 1,000.

The works are not merely shared; they are accumulated as "parts of a story" centered on a unique worldview, expanding as a participatory creative culture.

■ A Community of Over 100 People Spanning Across Borders

More than 100 people have participated in this project, with engagement spreading beyond Japan to countries including South Korea, Taiwan, and the United States. Related posts have reached approximately 120,000 users with about 1.28 million views, demonstrating significant traction on social media.

■ Evolving the Worldview into an "Experiential Event"

Following this momentum, "nene_hope_heart" is launching the participatory event "Kaguya Galaxy Cherry Blossom Viewing Party."

This event allows users to participate in the story through their submissions. Participants are invited to a dedicated community (group chat), where they can deepen their experience while sharing the brand's worldview in a closed space.

Within the story, each participant's work acts as a "cherry blossom" that helps bring the world into full bloom, with special rewards prepared for those who meet specific conditions.

■ Past Developments and Brand Evolution

To date, "nene_hope_heart" has not only planned and sold decorative PET tapes and design paper but has also exhibited at the department store-style commercial facility "CHOOSEBASE SHIBUYA" (https://choosebase.jp/) and released limited-edition products.

Leveraging its delicate designs and unique worldview, the brand is expanding beyond the conventional boundaries of a personal brand.

This initiative marks an evolution from a traditional product-sales model to an "IP-style brand" centered on user-participatory experiences and community building.

■ Future Outlook

Moving forward, the brand aims to grow by further expanding its reach through international development and collaborations, all while continuing to cultivate its worldview alongside its users.
