Nogizaka46's 22nd single "Kaerimichi wa Toomawari Shitaku Naru" has sold 1,063,000 copies during its first week on sale.
This is the 2nd time the group has sold over 1 million copies of a single during its first week on sale. This feat is usually only accomplished by rival group AKB48.
During its first week on sale, "Synchronicity" sold 1,116,852 copies. This was the group's first single to do so.
This is Nogizaka46's 6th single in a row to sell over 1 million copies.
Sales of the single were in part driven by Yumi Wakatsuki and Nanase Nishino's graduation from the group. This is the last single the two of them will participate in.
