TVXQ left no doubt that they really are the kings representing Kpop in Japan as they've just managed to help make history once again! 

The pair was recently featured as the cover models for Japan's monthly music magazine 'PATi PATi', and the issue sold out for the first time in the magazine's 30 year history! 

Japan's Oricon reported, "The monthly music magazine 'PATi PATi's August issue was sold out completely on the day of release. Due to the explosive response towards TVXQ, they've decided to reprint for the first time."

The publishers said, "In Japan, it's rare to hear of a magazine to be sold out. As soon as it was revealed that TVXQ were the cover models, we got a floor of pre-orders."
