Korean Wave star Kim Hyun Joong revealed that he cannot go into a sauna carelessly anymore.

On the July 21 broadcast of KBS "Entertainment News" Kim Hyun Joong revealed the scene of his concert in Japan.

On stage, Kim Hyun Joong stated after hearing enthusiastic shouts of male fans, "I've been gaining more male fans lately. It seems like I can't go to the public sauna so easily anymore."

He also said, "I have more 'noona' (older sister or lady) fans in Japan. It's so mind-blowing to me when I see a grandma in her seventies waving a glow stick. It makes me think that I need to work harder."
