It's because JE has been a staple in the Japanese music scene, ever since the late 70s. Tohoshinki's music has been total CRAP all year so they don't deserve that number one that they got, at all. JE boybands may not be the best singer, but their music has been consistently great and totally deserve their number one spots. JE is not just about singing, it's about dancing and acting also and JE also are amazing in those fields.
