 * February 11 & 12, 2023: Musashino Forest Sport Plaza in Chofu, Tokyo (Valentine's Day Concert)
 * March 11 & 12, 2023: Makuhari Messe Event Hall in Chiba, Tokyo (White Day Concert)

Trivia

 * White Day is observed in Japan on March 14 by the National Confectionery Industry Association as an "answer day" to Valentine's Day (which is observed exactly a month before), on the grounds that men should pay back the women who gave them chocolate and other gifts on Valentine's Day. The first observance occurred in 1978, and since then, its observance has spread to several other Asian nations and countries around the world, including China, South Korea, Taiwan, and Vietnam.
 * The costumes worn during the performances of "Yosoku Fukanou Driving!", "Waku-Waku-Week!", "Marine Border Parasol", "Kimeta yo Hand in Hand", "Tousou Meisou Mobius Loop", "Hajimari Road", and "SKY JOURNEY" originally appeared in the sixth issue of the LoveLive! Days magazine as the results of a costume design project that had "SKY JOURNEY" serving as the assigned inspiration.
 * For the performance of "BANZAI! digital trippers" during the encore, Hatsune Miku appeared to perform beside Aqours on a screen situated at the stage's bottom floor (behind the performers), a method replicating that featured in the original animated music video for the song.
 * The first performance of the aforementioned song, as well as "KA-GA-YA-KI-RA-RI-RA", were both performed by Aqours separately with pre-recorded vocals, though the online livestream during the former included sections where the camera focused on Arisa Komiya (Dia Kurosawa's voice actress) and Hatsune Miku either on-stage or on-screen respectively during the sections where they would sing or dance together.
 * This was one of the first live concert events in the franchise since Love Live! Fest where attendees were permitted to cheer in light of the Japanese government lifting some restrictions on rules and measures at live concerts held during the COVID-19 pandemic; however, attendees were still required to wear a mask in order to gain entry into the venue.
