今日、一人で東京入国管理国へ行きました。

東京JR 　→　品川 -->BUS-->東京入国管理国

If I want to back HK once or more within this year, I need to go for applying the card for forigners, which allow you to back Japan again. However, luckily, all forigners dont need to apply it anymore from 5-July 2012. So, if I dont back HK before that day, I dont need to apply it. great!!!as every application cost 6000YEN!!
