What Sunny Side Up does

Sunny Side Up Group (株式会社サニーサイドアップグループ) is a Tokyo-headquartered PR and communications holding company founded in 1985 and listed on the Tokyo Stock Exchange Standard Market (TYO:2180). The group employs approximately 500 people across Japan, Korea, Hawaii, India, and the Philippines, and is in the process of rebranding to "GOOD IMPACT GROUP" (announced 2026) to reflect an expanded focus on generating positive social impact through communication. The business is organized around five operating segments delivered through twelve-plus wholly-owned subsidiaries: integrated PR and communications consulting, event management, PR Tech / data-driven measurement, restaurant and lifestyle operations, and entertainment / education services.

The group's core technology platform is "PR Tech," a data-driven PR framework combining analytics with communications expertise. The January 2026 acquisition of Bilcom, Inc. (ビルコム株式会社) added the cloud-based PR effectiveness measurement tool "PR Analyzer," strengthening the group's measurement and analytics stack. A subsequent strategic partnership with note inc. (announced April 2026) is intended to produce a "next-generation PR model" for the AI era, branded as "B to A with C (Business to AI, with Consumer)," focused on packaging primary corporate information in AI-readable formats. The company earns revenue through professional-services engagements with quote-based, project-negotiated pricing (PR, events, communications consulting) supplemented by consumer-facing revenue from restaurant operations (the bills brunch chain) and media platforms (GOOD&NEWS, SUNNY DAYS). Customers are enterprise and mid-sized corporations served via direct sales across diverse verticals including retail, F&B, entertainment, sports, and government.

Operationally, the group pursues a horizontal segmentation strategy and a sales-led go-to-market model with dedicated account teams and project managers across its subsidiaries. The company carries meaningful intangible-asset credentials — B Corp certification (2024), ISO27001 (2025), Tokyo Metropolitan Women's Empowerment Promotion Award, and PRWeek Agency Business Report 2026 ranking of Asia 3rd / World 26th. Founder Etsuko Tsugihara (次原悦子) remains President and Representative Director, noted as a rare female founder-president of a Japanese listed company. In May 2026 the group announced a management integration with Akatsuki Inc. via a tender offer, which represents the single most consequential pending structural change.
