Bokutachi wa Tatakawanai

"Bokutachi wa Tatakawanai" (僕たちは戦わない) is the 40th single by the Japanese idol girl group AKB48. It was released in Japan on May 20, 2015. AKB48's Chinese sister group, AKB48 Team SH, made their own Chinese version of the song.

Background
Haruka Shimazaki serves as choreography center of this single's title song. It is also the last AKB48 single featuring members Rina Kawaei, SKE48 member Rena Matsui, and Nogizaka46 member Rina Ikoma, both two members (except Ikoma, who was a concurrent member of AKB48 and cancelled her concurrency after AKB48 Spring Shuffle will took effect) left the AKB48 group after the release of this single. Despite being the last single whom she appeared in, Kawaei is still featured in their next single Halloween Night (song), but in the coupling song “Yankee Machine Gun” as a graduated member.

Release
The single was released in several versions: Type A (two editions: limited and regular), Type B (limited and regular), Type C (limited and regular), Type D (limited and regular), and a version called the "Theater Edition". All versions, except the Theater Edition, include a DVD with several music videos.

The first presses of the single came with a ticket to vote in the AKB48 41st Single Senbatsu Election (to choose the members to be featured in the next AKB48's single, to be released in the summer.)

Music video
The music video for the title track was directed by Keishi Ōtomo, best known as the director of the Ruroni Kenshin movie series. Unlike other Summer-themed AKB48 singles, this single's MV does not have a paradise scenery and girls in bathing suits. Instead, they focused more on action and most complex choreography that had been set aside in "Kibōteki Refrain".

Reception
The single debuted at number one on Oricon's daily singles chart for the day of May 19, 2015, with sales of 1,472,375 copies. It also topped the weekly Oricon Singles Chart on the June 1 week, selling 1,673,211 copies. It also reached number one on the Billboard Japan Hot 100.
