Nogizaka46's flagship variety show 'Nogizaka Koji-chu' (Nogizaka Under Construction) trended across Japanese social media on the night of May 17–18, 2026, as the second half of its 'MV Behind-the-Scenes Championship 2026' segment finally aired after a two-week gap. The show, which airs Sunday nights at 24:15 on TV Tokyo affiliates and is hosted by comedy duo Banana Man, had been preempted the previous week when TV Tokyo ran a live broadcast of the World Table Tennis men's team final.

The two-week wait significantly amplified viewer anticipation. Japanese X was flooded with posts from fans counting down to the broadcast, with phrases like 'finally' and 'two long weeks' appearing across hundreds of posts. The 'MV Koko Mite' (MV Look Here) format is one of the show's most popular recurring segments, in which members reveal candid behind-the-scenes stories from their music video shoots — the kind of unscripted, personal content that drives strong fan engagement.

The episode's biggest talking point was member Reina Ozu (6th generation, age 17). Ozu had been on academic hiatus since June 2025 and officially returned to activities on April 6, 2026. According to Music Natalie, she is also confirmed to appear all three days of the Tokyo Dome '14th YEAR BIRTHDAY LIVE' on May 19–21, 2026.

This episode marked her first opportunity to share post-return anecdotes on the show, including the revelation that she had secretly appeared in a 6th-generation MV — a detail that generated significant buzz even before the episode aired, after entertainment media reported it earlier in the day. Other highlights included member Kaki Haruka sharing that her MV was filmed at a coin laundry because her character was set up as having no money — a detail that spread widely on X during the live broadcast.

What to watch next: Reina Ozu's full reintegration into Nogizaka46's activities will be closely watched, with her Tokyo Dome Birthday Live appearances on May 19–21 serving as the next major milestone. Additionally, the Lemino streaming spin-off 'Nogizaka Koji Encho-chu,' which launched April 6, 2026 and streams every Monday midnight (¥1,540/month, first month free), released its latest episode simultaneously with the TV broadcast — a dual-platform strategy that is likely to continue amplifying weekly engagement.
