"Seifuku ga Jama o Suru" (制服が邪魔をする, (School) uniform is getting in the way) is Japanese idol group AKB48's fourth single, and the second major single released through DefSTAR Records, on January 31, 2007.[1] The title track was sung with 14 members,[2] 6 members fewer than their last single "Aitakatta".
Music video
"Seifuku ga Jama o Suru" drew public attention with its controversial music video, which is a literal visualization of the lyrics, somewhat hinting at the subject of enjo kosai.[2] Even the sales copy on TV commercial was "Otousan, gomennasai" (お父さん、ごめんなさい, Sorry, dad), a comment made by Maeda, who played a key role on its video clip. As its lyrics indicates, the video clip was filmed in Shibuya.[2]
Each "Shokai Genteiban" (初回限定版, The first edition) CD also includes 2 DVDs, one is video clip and the other is "Making of "Seifuku ga Jama o Suru", as well as following premiums.[3]
Original Trading Cards (one of 3 different designs)
A flyer for premium application
CD sleeve in different design
There was a surprise live performance at two locations in Shibuya on the release date January 31, 2007.[4]
Reception
Since many "Aitakatta" limited editions remained unsold, the Seifuku ga Jama wo Suru limited sets were produced in a smaller quantity, making it one of the rarer to find releases.[2]
The single charted 5 weeks in the top 200 with the highest rank at #7, the highest ever record for AKB48.[5] But "Seifuku ga Jama o Suru" wasn’t quite as well received[2] as it only sold 21,989 copies.
