I don't even know who is Arashi or what so ever. Even though I love Super Junior, I would have to admit thet DBSK is the most popular boyband...correction....is in the world. Second comes Super Junior.<the one that I love. Shinhwa is kinda popular too as they are the longest boyband to stay together. Big Bang is also chasing up.

Wat About Kat Tun I like them and News and Fahrenheit

DBSK , BIG Bang and FT island !!!!!!!!!!!!!!!!!

lol F4 was popular around like 2003 until their waves died.

Though I'm not a fan, it's kinda a given that DBSK have the absolute largest worldwide fanbase

Probably F4 or Big Bang?
Those were da first groups i heard of couple yrs. baCc.

DBSK. Obviously .
Super Junior is also rising up because of their Don't Don album.
Big Bang is also chasing up to the top.

Fahrenheit

Dong Bang Shin Ki & Maybe Super Junior (not they are like No.1 in China, Taiwan and Korea though)

TVXQ, i think

Back in the early 2000s it was F4 now its TVXQ....
