Sotsugyō Shashin Dake ga Shitteru

As with the previous single, "Sotsugyō Shashin Dake ga Shitteru" implemented a "selection" (選抜, senbatsu) system, where only selected members would perform the title track, while unselected members would be assigned to the understudy group, Hiragana Hinatazaka46 (ひなた坂46). Second generation member Nao Kosaka returned as center (lead performer) for the first time after "Boku Nanka" (2022).^[1]

Kumi Sasaki, Mirei Sasaki, and Mana Takase, the last remaining founding members, would leave the group after the promotion of this single and performed the B-side track "Instead of You".^[2] "Suzuka", performed by Hiragana Hinatazaka46 with lyrics describing its center Suzuka Tomita, has been noted for being unusually titled after a member.^[1][3][4] "Ashi no Koyubi o Tansu no Kaku ni Butsuketa" was performed by the group's fourth generation members.

"Sotsugyō Shashin Dake ga Shitteru" was released on physical media on January 29, 2025, in five editions: four limited editions (Types A to D) featuring Blu-ray discs, and a regular CD-only edition.

"Sotsugyō Shashin Dake ga Shitteru" debuted at number one on the weekly Oricon Singles Chart, selling over 428,000 physical copies in its first week.^[5] This marked Hinatazaka46's 13th consecutive number-one single since their debut, extending their record as the female artist with the most consecutive number-one singles since a debut release. The single's digital Special Edition also debuted at number one on the Oricon Weekly Digital Albums ranking.^[6]

The single's music video was highlighted for its spring-evoking visual presentation. CDJournal noted that the video's theme revolves around a "parade heralding spring", portraying nostalgic graduation day scenes and dynamic dance sequences set amidst a "blizzard" of cherry blossom.^[6]
