On March 3rd, singer IU appeared at the Yokohama Arena for the '14th Tokyo Girls Collection 2012 Spring/Summer'.

IU performed the Japanese version of "Good Day". A couple of days ago, IU had to cancel an event in Korea because she was too ill. Despite being sick, she performed her high notes perfectly and received a lot of praise. 

The event 'Tokyo Girls Collection 2012 Spring/Summer' had a theme of 'Sherbet Garden' and featured 100 top models who wore the most trendy outfits for Spring and Summer of this year. Over 27,000 people were recorded to have shown up for the event.

IU wore an adorable black and white mini-dress and performed very energetically.

IU will debut in Japan with her single album "Good Day" on the 21st of this month.
