"1,000 Posts by a Personal Brand": The SNS-Born Collage Culture Created Through 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 strengthening its community-based approach by launching a participatory event called the "Kaguya Galaxy Cherry Blossom Viewing Party." ■ A Participatory Collage Culture Born from a Personal Brand, Exceeding 1,000 Posts "nene_hope_heart" is a personal creative brand that plans and sells decorative PET stickers and design paper. The brand's hashtag project on social media, "#celestialpirates2026," adopts a format where users post their own works based on a shared theme. As a result, the total number of posts has exceeded 1,000. The works go beyond simple sharing; they are accumulated as "parts of a story" centered on a unique worldview, spreading as a participatory creative culture. ■ A Community of Over 100 People Expanding Overseas More than 100 people have participated in this project, with involvement spreading beyond Japan to countries including South Korea, Taiwan, and the United States. Related posts have reached approximately 120,000 people, with about 1.28 million views, demonstrating significant traction on social media. ■ The Worldview Evolves into an "Experiential Event" Following this momentum, "nene_hope_heart" is launching the participatory event "Kaguya Galaxy Cherry Blossom Viewing Party." This event allows participants to join the story through their submissions. Participants are invited to a dedicated community (group chat) to deepen their experience while sharing the worldview in a closed space. Within the story, each participant's work becomes a "cherry blossom," with the setting designed to lead the world to full bloom. Special rewards are also available for participants who meet certain conditions. ■ Past Developments and Brand Evolution To date, "nene_hope_heart" has planned and sold decorative PET tapes and design paper, as well as 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 traditional scope of a personal brand. This initiative marks an evolution from a traditional product-sales-focused model to an "IP-style brand" centered on user-participatory experiences and community building. ■ Future Outlook Moving forward, the brand aims to grow by fostering its worldview together with its users, with plans to expand further through international outreach and collaborations centered on its community and unique narrative. ■ Reference Information ・Hashtag: #celestialpirates2026 ・Number of posts: Over 1,000 ・Number of participants: Over 100 ・Reach: Approx. 120,000 (recent monthly) ・Views: Approx. 1.28 million (recent monthly) ・International participation: South Korea, Taiwan, USA, etc. ■ Brand Introduction nene_hope_heart is a personal creative brand focusing on decorative PET stickers and design paper.
