Today on Sept 29th, AKB48 releases it's 58th single Nemo Hamo Rumor.
The first day sales of AKB48's single "Nemo Hamo Rumor" amounted to 320,489 copies and ranked 1st on the Oricon Daily Chart.
This sale is much lower than the previous single "Shitsuren, Arigatou" which was sold about up to 1,150,839 copies on the first day.
The absence of sister group members in the AKB48 58th single is not just a matter of some sister groups' Ace not entering the senbatsu anymore.
There is no more online talk session (substitute for handshakes) for all sister group members (hundreds of members), meaning that the potential for CD sales from there is drastically down compared previous singles.
