Rejuran Targets Rising Female Baseball Fans with First Beauty Industry Ground Painting Ad at Seoul Jamsil Stadium

이현 -

South Korea’s professional baseball league is enjoying record breaking momentum in the early stage of the 2026 season, with growing numbers of young female fans reshaping the marketing value of stadium media.

According to the Korea Baseball Organization (KBO), cumulative attendance reached 2.09 million as of April 25, surpassing the two million mark in just 117 regular season games. It broke the previous fastest record of 118 games set last year.

Industry analysts say one of the biggest drivers behind the surge is the rapid increase in women in their 20s and 30s. Ticketlink data showed women accounted for 57.5 percent of online ticket bookings during the 2025 season. Among fans in their 20s and 30s, who represented 60 percent of all bookings, female shares reached 63.6 percent and 56.9 percent respectively.

The shift is changing how advertisers view baseball venues. Stadiums are no longer seen only as places to watch games, but as lifestyle destinations combining entertainment, social experiences, food, merchandise shopping and photo opportunities.

Reflecting this trend, Rejuran, a premium skincare and aesthetic beauty brand operated by South Korean biopharmaceutical company PharmaResearch, launched the beauty sector’s first ground painting advertisement at Jamsil Baseball Stadium in Seoul.

The campaign is positioned near the first base VIP seating area, one of the most visible zones inside the stadium. Measuring 8 meters wide and 4 meters high, the branding uses strong contrast against the field surface to maximize visibility for both live spectators and television audiences.

Because the logo appears repeatedly during game broadcasts and key match moments, advertisers consider ground painting one of the most effective premium media assets inside baseball venues.

With the KBO League expected to challenge a historic 13 million attendance milestone this season, demand for sports venue advertising is also expected to rise. As younger female audiences continue to expand, marketers from beauty, fashion and lifestyle sectors are likely to increase investment in baseball based brand campaigns.
