leaving japan back to home country

Hello
I'm currently working as a Graphic Designer here in japan.
I have my wife & son living with me.
my wife & I decided to go back to our home country & not coming back.
I ask my employer if can bring my Job and continue working from my country, and they said YES, In fact, they want me to build a design team so that I can provide more designs for them.

But, my question is, i think will gonna miss this place, the environment, the nature, the quit, etc, coz this was my dream to work and lived here.

Well you canft have it all.
Maybe ask your employer if you can come for frequent business trips. You obviously need to make some business case why youfd need to be several weeks/ months in Japan every year and convince your wife why youfll be away for so long. Tricky.

You cannot have it all. You say your wife and you made the decision to leave, so youfd have to live with the consequences. Or change the decision. I donft know why you decided that way.
