Welcome Vincent.
I too, missed living in Japan after spending many years in the country. I've recently moved back and wake with a big smile on my face every day .... Something I haven't been able to say for a long long time.
There are still many frustrating things about this country (I'll probably have a good whinge later!!) but I'm glad I made the move again.
Hope you, too, are able to get back to Nihon someday.
