AKB48 Sustainable total sales is the worst in 5 years

Even though it sold "so much" according to Oricon Weekly Chart rank, the 56th AKB48 single SUSTAINABLE in sales was still the worst in the last 5 years. While Jiwaru DAYS still occupies the top position, this is likely due to the absence of talented members in the influential senbatsu line up, plus Yahagi Moeka scandal factors.
