Visa for potentially Skilled Worker/Labourer.

Hi all. I have been residing in Japan with my partner (who is Japanese) on a working holiday Visa myself for the last year, my visa ends at the start of December and will be heading back to my own country for a while while I sort out money, visa stuff etc.

I am employed as a landscape gardener here in Japan and enjoy my job doing as such and have learned a lot and have qualifications and certs in regards to landscaping and construction.

I am just wondering, what Visa is available to me as someone looking to reapply to come back here and work. I will be taking my N4 test next month and specified skilled worker sticks out the most as it deals with labour shortages and the likes.

Thanks for any input!
