After the news broke out that a mega-scale Hallyu event – with the attendance of Lee Byung-hun, Jang Dong-gun, Song Seung-hun and Won Bin – is going to be held on December 17 in Tokyo, people are wondering how huge of a crowd the event will succeed in attracting.

The fans are showing tremendous reaction to the news. With each celebrity being huge Hallyu stars, the local fans could not believe all four would appear at a single event and even doubted the authenticity of the news. The ticket price of 15,800 yen (US$180) is getting some complaints though.
