On the night of May 24, 2026, Hinatazaka46's long-running variety show 'Hinatazaka de Aimashou' (nicknamed 'Hinaai') aired its 358th episode on TV Tokyo, triggering a wave of live-tweet reactions that pushed the show's hashtag to the top of Japanese trending lists. The episode was the second half of a recurring fan-favorite segment: a competition to determine the 'official big sister' (koushiki onee-chan) for younger member Sakai Niina. In the first half, the presumed frontrunner Ohno Manami was eliminated in what fans are calling the 'Cola Incident' — a classic variety-show twist that left the outcome wide open heading into this week's finale.

The moment that generated the most buzz was a line from member Takahashi Mikuni: 'Voyeurism is a crime, right?!' — an unexpected outburst that entertainment site WEB The Television described as a 'yellow card moment.' Fujishima Kaho also drew attention for her distinctive vocal reactions, with fans quoting her throughout the broadcast.

The show's chaotic energy — including a running gag about rules being broken and a Conan theme music cue — kept the live-tweet stream active well past 1 AM. Separately, Fujishima Kaho is making headlines as the first member in Hinatazaka46's history to serve as a solo center, for the group's 17th single 'Kind of love.' She told media she wants to become 'a center loved by everyone,' adding another layer of fan interest to her appearance in this episode.

What to watch next: The episode is now available as an exclusive catch-up stream on Lemino (Japan only) from 1:50 AM on May 25. International fans can follow official Hinatazaka46 social channels for clips. The 17th single 'Kind of love' with Fujishima Kaho as solo center is also a key upcoming release to watch.
