Shiawase no Hogoshoku

"Shiawase no Hogoshoku" (しあわせの保護色) is the 25th single by Japanese idol group Nogizaka46. The single was released on 25 March 2020.

The center position of the title track was held by Mai Shiraishi. This single was intended to be the last one that Shiraishi performs in before she leaves Nogizaka46, and as such was written as a tribute to her; however, she delayed her graduation due to the COVID-19 pandemic and was present in "Sekaijū no Rinjin yo", the next song released. Shiraishi also wrote and performed solo the Type-A coupling song "Jyāne" (じゃあね), marking the first time someone other than Yasushi Akimoto has written a song for Nogizaka46.
