As of this writing, he is already airborne and a few minutes from now his plane would be taxiing in Kimpo. It's only a day trip to Japan this time around.
Here is a video of Hyun Joong arriving in Henada greeted by his Japanese fans.

Btw, at the presscon, Hyun Joong was asked about Oguri Shun who got married on White Day (which is today also in Japan). Hyun Joong said that we would have wanted to sing a song of congratulatory to Oguri and his wife, Yamadu Yu but since he cannot, he instead sang 'I'm Your Man' acapella at the presscon. For some who might be interested to know, Hyun Joong and Oguri Shun played the same character in 'Hana Yori Dango/Boys Over Flowers' and met each other sometime last year or two years (if my memory is correct).
