What is the departure order system?

The "departure order system" is a system in which foreigners who are illegally residing in Japan can return home without being detained by appearing at the immigration bureau voluntarily.
If you return to Japan under "forced deportation", you cannot re-enter Japan for 5 or 10 years, but if you return to Japan under "departure order system", the period will be one year.
The "departure order system" is a very beneficial system for those who wish to re-enter Japan.
However, in order to use this "departure order system", it is necessary to meet the conditions such as appearing at the immigration bureau by yourself and not having any violations other than illegal stay.
