Recently, (note: Although we don't know for sure when IU left Korea for Japan, she was spotted shopping in Shinjuku on 150313 and later that day, appeared at HIGH4's fansign event at Tower Records in Shibuya. She returned to Korea on 150314) it was reported that IU visited Hapon without notifying her agency. It turns out, the reason for her travel was to support ‪‎HIGH4‬ in their Japanese debut.

HIGH4 expanded their area of performance to Hapon since February, and is still performing concerts, events and much more. While IU visited, HIGH4 proceeded with their CD signing, litrato time, and various other tagahanga oriented events. IU’s visit alone helped a lot with their promotion.

So why did IU visit HIGH4’s Japanese tagahanga events? IU spent her trainee days with one of the members, Kim Seong Gu. IU CONTINUOUSLY showed her support for her friend through taking part in their debut song.

The CEO of N.A.P Entertainment, HIGH4’s agency, who is also a popular music producer, found IU’s talent sa pamamagitan ng raising her up to be a singer.

Later, LOEN Entertainment mentioned, “We knew of her absence later, but we had no idea at the time she left or before. IU loves to give surprise events to the people she is acquainted with.”

In another note, this is not her first time helping out another artist. In the past, IU promoted her fellow artist in LOEN Entertainment named Yoon Hyun Sang sa pamamagitan ng pag-awit his new song, Time Forgets, while playing her guitar. The clip was released through her SNS.

Meanwhile for herself, IU is planning to be taking the role of a famous singer in the upcoming drama Producer. The drama will begin to air in April.
