Nogizaka46 releases 'Sora Tobira' MV

Nogizaka46 put the full music video for “Sora Tobira” back on YouTube on May 13, reviving a 2018 release tied to the group’s 21st single, according to the group’s official website. The reissue came ahead of Minami Umezawa’s graduation concert on May 21, where the group billed the song as one she had centered. A fan account on X, harachan_Si, circulated the YouTube link on May 21, helping push attention toward the official upload. The video was available through Nogizaka46’s official YouTube channel, which the group uses for music videos and related releases. ### Why did “Sora Tobira” resurface now? Nogizaka46’s official site said on May 13 that the 2018 “Sora Tobira” music video had been re-released on YouTube before the May 21 “Minami Umezawa Graduation Concert.” The post described “Sora Tobira” as a song on the 21st single “Jikochuu de Ikou!” and said Umezawa served as center on the track. (nogizaka46.com) May 21 was already a key date in the group’s calendar. Nogizaka46 had scheduled Day 3 of its “14th YEAR BIRTHDAY LIVE” at Tokyo Dome as “Minami Umezawa Graduation Concert,” according to the event page and ticket notice on the official site. ### Was this a brand-new video or an older one? The group’s own notice said the upload was a re-release of a music video produced in 2018. (nogizaka46.com) That distinguishes it from a new shoot: the official language points to an older work being restored to the group’s current YouTube distribution rather than a newly filmed promotional clip. (nogizaka46.com) Nogizaka46 had previously posted a short version of “Sora Tobira” on YouTube years earlier. The newly circulated upload was labeled “Music Video,” while the older public clip was labeled “Short Ver.,” indicating the May 2026 post gave viewers access to a fuller official version on the group’s channel. ### What do the official posting details show? YouTube metadata for the official upload showed the video had been published “4 days ago” when it was indexed on May 22, and the description referenced the May 21 graduation concert. (nogizaka46.com) The same page showed roughly 303,000 views and about 20,000 channel likes or subscribers displayed alongside the upload snapshot returned by search. (youtube.com) Nogizaka46’s official YouTube channel describes itself as the group’s official channel for music videos and video releases. That makes YouTube the primary public platform for this reissue, even as fans amplified the link on X. ### Where did the social sharing come from? A social briefing supplied with this story identified an X post by user harachan_Si on May 21 linking to the “Sora Tobira” music video on YouTube. (youtube.com) The briefing said fan sharing around that post drew engagement on the day of Umezawa’s concert and pointed viewers back to the official YouTube upload. The official site’s timing supports that sequence. (youtube.com) Nogizaka46 announced the re-release on May 13, and fans were still circulating the link on May 21 as the graduation concert took place. ### What comes next for viewers? May 24 is the next dated milestone attached to this release cycle. Nogizaka46’s ticket notice said the May 21 graduation concert would receive a single repeat stream on May 24, with sales handled through Stagecrowd and Rakuten TV for the paid online broadcast. (youtube.com) The “Sora Tobira” video remains on Nogizaka46’s official YouTube channel, where the group linked viewers in its May 13 announcement. (nogizaka46.com) Fans looking for the song after the concert are being directed to that official upload rather than an unofficial repost. (nogizaka46.com)
