How challenging its to get a cloud engineer job in Japan - be brutally honest with english language, no japaness yet

I got some experience in pre-sales, but not directly in technical deployment role.

Got a few certifications for both azure and AWS. My main issue is lack of acutal deployment skills.

Got a few persoanl projects and I can confidently say that I got enougth knowledgmet how on premise and cloud infra work.

Im thinking to go to Japan under language school visa and plan to get a job within 5 months ( as soon as possible ) then keep improving japaness skill while working.

Any advise on this based on the current market in japan
