Mitsui O.S.K. Lines Sunflower Co., Ltd. (President: Hirotoshi Ushioku, Headquarters: Chiyoda-ku, Tokyo; hereinafter "the Company") will launch a collaboration project "Chiikawa x Sunflower: Chiikawa and a Relaxing Cruise" with 'Chiikawa the Movie: The Secret of Mermaid Island,' starting with departures on Thursday, August 6, 2026.
To deliver the joy of ferry travel to more customers, the Company has previously developed various collaboration projects. This time, we will implement a collaboration with the first movie adaptation of the popular character "Chiikawa."
We plan to offer activities that make the travel time itself enjoyable while immersing visitors in the world of "Chiikawa," as well as selling original Sunflower collaboration merchandise.
'Chiikawa the Movie: The Secret of Mermaid Island' depicts Chiikawa and friends sailing to an island. By overlapping the world of the movie with a ferry journey, this project aims to make the appeal of the work and the ferry travel more enjoyable and accessible. Through this initiative, we aim to make "Sunflower" travel a destination itself, providing many customers with an opportunity to experience a new kind of ferry journey.
