- The Danza: All of the girls have the same first and last names as their respective actresses. They even have some similar personality traits. It's not a stretch to say they're almost playing fictionalised versions of themselves.
- International Coproduction: The show was co-produced by TV Tokyo and Netflix, and naturally distributed internationally by the latter.
- What Could Have Been: Miho's role originally belonged to Nagahama Neru, a former member of Hiragana Keyakizaka46 who was "transferred" to Kanji Keyakizaka46 before the drama started. They did an audition among Hiragana's 2nd gen to find a member who could replace Neru's role, and Miho was chosen. In an interview, the cast revealed that Miho and Kumi's unseen best friend is actually Neru.
- Word of Saint Paul: Some of the loose ends are explained by the actresses in their blogs. For example, Saito Kyoko confirms that the room is on a ship and claims that everybody survives and graduates the next day (i.e. the beach ending scene is not a Dream Sequence).
