In the previous system, you had to go to the regional immigration bureaus to get a re-entry permission every time you left Japan, for example to visit your home country or to go on a business trip.
Sa kasalukuyang sistema ay kailangang pumunta sa regional immigration office at kumuha ng re-entry permission kung aalis kayo ng bansang Hapon, tulad na umuwi sa inyong bansa o business trip.
