Is it possible to return?

I have been in japan for 2 years almost and wanted to return to my home country for 3 weeks or so. But my visa will expire in 3 month and 1 week.

So can i return to my country and come back to japan and apply for extension of visa?

Note: visa expire in 20 April 2026, wanted to visit home country from 20 Jan to Feb 10 2026.
