What by SANJUKUDO does

SANJUKUDO Inc. (サンジュクド株式会社) is a Tokyo-headquartered creative production company founded in 2020, with a Seoul operation under SANJUKUDO KOREA. Led by CEO Sanggoo Sun and COO Yoshihiro Nagano, it serves luxury and fashion brands, publishers, music labels and artists, and entertainment or anime intellectual-property owners in Japan and South Korea. Its services cover creative planning, commercials, music promotion, graphic and web design, event promotion, talent casting, and creator management.

The company operates as a collective of freelance directors, cinematographers, photographers, designers, and sound directors assembled around individual commissions. Its outputs are project-based creative assets—including campaigns, music videos, social content, web content, and experiential promotions—rather than a disclosed software or subscription product; no proprietary platform, model, or delivery architecture is described.

Commercial activity is visible through recurring ViVi Magazine work for CHANEL, Dior, and PANDORA; music and promotional projects involving LE SSERAFIM, ITZY, JO1, and TWS; Sanrio collaborations; and Attack on Titan, Demon Slayer, and BLEACH Night Walk experiences. The supplied material does not disclose contract values, revenue, funding, headcount, or customer-level revenue mix, so pricing power, utilization, and margins cannot be verified.
