ONE OK ROCK bassist Ryota (37) and model and entrepreneur Saeko (39) have sparked dating rumors after being spotted together at Haneda Airport in Tokyo, according to a report by Japanese weekly magazine FRIDAY.

The magazine reported that the two were seen at the airport in early October, preparing to travel to South Korea.

They reportedly appeared close throughout the check-in process, with Ryota placing his arm around Saeko's waist before the two walked hand in hand toward the departure area.

According to a source cited by FRIDAY, Ryota and Saeko previously knew each other through Horikoshi High School in Tokyo and reconnected earlier this year through a mutual acquaintance. The source also claimed that Ryota, who has an interest in photography, visited Saeko's farm to photograph horses.

Saeko was previously married to professional baseball player Yu Darvish, with whom she has two children.

Ryota announced his divorce from Michelle, the younger sister of singer Avril Lavigne, in September 2025.

FRIDAY published additional details about the reported relationship in its October 9 issue. Neither Ryota nor Saeko has publicly confirmed their relationship.
