Keyakizaka46's debut studio album "Masshirona Mono wa Yogoshitaku Naru" is the best selling album of the past week.
According to Oricon, the group's highly anticipated album sold 279,000 copies during its first week of sales. This made it the #1 album on its weekly album chart.
The new album had the best first week sales of a debut album in over 4 years, and is the only debut album to sell over 250,000 copies during the same period. The last debut album to achieve this was NMB48's "Teppen Tottande!" in 2013.
Keyakizaka46 sold more copies of its debut album than its sister group Nogizaka46's debut album "Toumei na Iro". That album sold 222,000 copies during its first week on sale.
