Nogizaka46 released their new single "Saigo ni Kaidan wo Kakenagatta no wa Itsu da?" (When Was the Last Time You Ran Up Stairs?) today, March 22nd, with digital streaming now available. The release comes with an accompanying music video that premiered on YouTube.

The single features Ikeda Teruasa as the center member, marking another spotlight moment for the third-generation member who joined the group in 2016. The music video concept explores the boundary between "fiction" and "reality," suggesting a more conceptual approach to the group's typical visual storytelling.

Nogizaka46, one of Japan's most successful idol groups and sister group to AKB48, continues their prolific release schedule with this new track. The group, managed by Sony Music Records, has maintained their position as one of the top-selling female acts in Japan since their debut in 2011.

The title's reflective nature - asking when someone last ran up stairs - hints at themes of nostalgia and the passage of time, fitting with the group's recent evolution as many founding members have graduated. The choice to feature Ikeda Teruasa as center also represents the group's ongoing transition to newer generations of members taking leading roles.

Fans can stream the new single on major digital platforms, while the music video offers the visual component that has become central to Nogizaka46's releases.
