ここにいたこと by AKB48

Koko ni Ita Koto (ここにいたこと, "We Were Here") is the third album by the Japanese idol girl group AKB48. "Koko ni Ita Koto" was released in Japan on June 8, 2011 by King Records. There are three versions available: Limited Edition (catalog number KIZC-90117/8), Regular Edition (KIZC-117/8), and Theater Edition (NKCD-6546). While all the group's albums had been almost entirely collections of previously released material, "Koko ni Ita Koto" took a different approach. Although it featured four 2010 hits, one theatre stage song, and a theme from an early 2011 movie, the rest were new songs.It met with great commercial success, topping the Oricon Weekly Albums Chart and, with just one week of sales, placed second in the list of best selling albums of the first half of 2011 in Japan. In the same month, it was already certified Million by the Recording Industry Association of Japan for shipments of over one million copies.
