A cafe named after and inspired by the viral song Pen-Pineapple-Apple-Pen, otherwise known as PPAP, has opened in Tokyo's SkyTree Town. Japanese comedian Pikotaro posted the unusual 51-second song to YouTube on August 25 and, after a recommendation by Justin Bieber, Pikotaro's song received over 144 million views in just two months. The single itself reached number 2 on the Billboard Japan Hot 100 chart and became the shortest single to chart in the Billboard Hot 100.
