It’s been over half a year, but IU and her hit song from last year, ‘Good Day’, are still going strong. When she went over to host SBS’s “Fighting Japan! Seoul - Osaka Music of Heart”, she performed ‘Good Day’ to the delight of many Japanese fans.

Currently, there is no set date for if she will debut in Japan and has only performed in a few shows to get some promotion in Japan. And with the popularity of the 3-octave high song performed in Japan, it looks as if IU will do well in Japan if she were to debut in Japan, especially a remake of her ‘Good Day’.

Watch her performance below!

I would like to see a Japanese version of ‘Good Day’. What about you?
