Why within the next 6 months ? Immigration will let you in when they will, no matter what route you try, and it might take longer than that for a myriad different reasons. Also, do you actually know anything about the country other than what you've seen from outside or experienced visiting for business or a holiday ? In my several decades living in Japan I've seen again and again foreigners hitting a number of walls that were always there and will always be there and getting out swearing never to come back again. Do you speak the language ? Otherwise you'll be in a bubble. Are you prepared for living with the constant threat of natural disasters, typhoons, quakes ? ( Forget any lucrative ideas about "property" and "real estate" ... ) And let's not get into the work environment you're going to be in. Finally, consider that unless you become Japanese ( good luck with that ), you will always be a 'guest', and that's the best case scenario, because you can be unceremoniously told to leave right now, or be prevented from returning if overseas -- as the pandemic has proved, when even "permanent residents" were separated from their homes, jobs, and families with no clue when they would be able to resume their lives, if ever. If none of this gives you pause, start by trying to transfer temporarily from an overseas company with offices in Japan and see how it goes. Most people I know who did that went back home after a couple of years, but some stayed. Edit : I assume you're a man. If you are a woman, then I'll just straight up say, better think of Singapore or Taiwan instead.
