SHINee was originally scheduled to have their Japanese debut in March but after the earthquake and tsunami, their debut was pushed back tentatively to May. With Girls’ Generation’s upcoming original single “Mr.Taxi,” on track to be released this month, it looks like SHINee’s debut will also be happening as planned in May.
A mastering engineer for Sonic Korea tweeted on April 21st that he was, “in the middle of mastering SHINee’s Japanese debut single!” 
What kind of concept will they introduce to Japan?
