[About Septeni's TikTok-Related Services]
Septeni established a specialized organization and began early-stage operations of TikTok advertising in October 2018, coinciding with the platform's launch in Japan. Leveraging the extensive expertise and technical capabilities accumulated since those early days, we continue to lead pioneering initiatives aimed at maximizing advertising effectiveness.

In July 2024, we established the "Short-Form Video Development Department," specializing in the planning and production of vertical creative content and short-form dramas. This has further strengthened our support system for corporate promotions using TikTok. In addition to our proven track record in direct response advertising for web and app domains—long a core strength—we have expanded our reach into branding and global projects since fiscal year 2025. Our ability to generate high performance across all TikTok-related domains has been highly recognized in the market.

Furthermore, Septeni is certified as a "TikTok Shop Partner (TSP)," an official partner of TikTok Shop, providing comprehensive support for corporate marketing activities utilizing e-commerce. Through these initiatives, we offer seamless, end-to-end marketing support across the entire funnel—from direct response and branding measures via ad operations to the purchasing experience on TikTok Shop.

*CARTA HOLDINGS (including CARTA ZERO) became a direct subsidiary of NTT DOCOMO in January 2026 and continues its business and capital alliance with the Dentsu Group. As this award recognizes achievements in 2025, CARTA ZERO was part of dentsu Japan at that time.
