Music video for Ponytail to Shushu (ポニーテールとシュシュ, lit. Ponytail & Scrunchy) by Japanese pop group AKB48. The MV was filmed in Guam, with plenty of bikinis, sunshine and beaches; plus a slightly NSFW prelude and a weird doggy.
Contrary to their conservative neighbours, it’s pretty common for mainstream Japanese idols to don in bikinis for MV/pictorials beside the fact that most of them are doing so at teen age. It’s almost a cultural thing, as you can hardly find a popular Japanese female star who has never shot a bikini video or photobook.
The single is doing well with over 500,000 copies sold in the first week after it was released (on May 26). It’s one of the year’s best selling singles to date.
