Shikoku Chemicals Holdings Corporation (Headquarters: Marugame City, Kagawa Prefecture; Representative Director and President: Mitsunori Watanabe; hereinafter "the Company") will begin sponsoring Nippon Broadcasting's late-night radio program "All Night Nippon" on Tuesdays, which is broadcast on 36 national stations with Nippon Broadcasting as the key station, starting from April 2026, with the first broadcast featuring Ichiro Yamaguchi of Sakanaction, who will be taking on the role of new personality.

Coinciding with the start of this sponsorship, the Company will broadcast its original commercial for the first time on a nationally networked radio program. This commercial was produced with the aim of widely recognizing the Company's name through a familiar melody, "Do you know Shikoku Chemicals♪."

"All Night Nippon" has been loved by many listeners since its first broadcast in 1967, with personalities who have colored the times. We are very pleased to be able to start sponsoring the program at this new milestone with Mr. Yamaguchi's appointment, and we aim to expand contact points with the next generation of listeners and improve brand recognition.
