M!LK's Taichi Shiozaki Reportedly Dating Sailor Moon Actress Rina Koyama

A Japanese entertainment outlet has reported that Taichi Shiozaki, 25, a member of the popular idol group M!LK, is secretly dating actress Rina Koyama, 23.

According to the report, Koyama, who is known for appearing in a stage adaptation of the long-running Sailor Moon franchise, has frequently visited Shiozaki's apartment.

The article characterises the pair's romance as a secret relationship, implying that the couple has deliberately kept their connection away from public knowledge until now.

Shiozaki has been described in the report as a national idol, a phrase commonly used in Japan for entertainers whose fame extends across the entire country, which explains the intense media interest in his private life.

Neither Shiozaki nor Koyama has issued any public statement confirming the alleged relationship, and the claims remain based solely on the outlet's reporting.

The same report also touched on M!LK's recent public activities, noting that the group performed a dance backstage at a stage production known as Ebirai, appearing in a fluffy fur-trimmed long coat as part of their styling.

Fans took to social media to comment on details from the performance, expressing appreciation for individual members' expressions, hairstyles and stage presence.

In addition, the report highlighted the group's fashion sense more broadly, praising what it called a sophisticated monotone aesthetic, ranging from an all-white, prince-inspired ensemble to a glamorous black coordinate.

Commenters online reportedly described the group's styling as impressively polished, reflecting continued public enthusiasm for M!LK beyond the dating speculation surrounding Shiozaki.

As of publication, the relationship between Shiozaki and Koyama remains unconfirmed by either party, and further details have not been made available.
