is the 67th single from the Japanese girl group Morning Musume. It was released on June 12, 2019, in five editions: two regular and three limited.[2]
The single was announced at a concert of the group's spring tour that took place in Hokkaido, and this is the first since 2011 to not include Haruna Iikubo as a member of the group, but in the music video for "Jinsei Blues" it does a cameo, and the last one to be released in the 2010s.
YOSHIKO made the dance for "Jinsei Blues" robotic and clock-like because the intro reminded her of Disney's Electrical Parade. She also added a "jinsei pose" of the 人 (hito) kanji in the chorus. The choreography for "Seishun Night" was changed several times. The first version was only performed at Hello! Project 20th Anniversary!! Hello! Project Hina Fes 2019. Afterwards, gradual changes were made to parts of the dance throughout the first half of Morning Musume '19's spring concert tour. The final version, which was a completely new dance, was first performed in Fukuoka on April 27, 2019.
