As you are planning to get from where you are to Japan you need to have some kind of strategy. I suppose that it is easy for an old guy like me to tell you all the things you need to do, and you may not believe me. That is very understandable. In the West, particularly to the newly graduated from university, you have not been given the advantages you should have received. Crushing student debt, “internships” which amount to unpaid volunteer labor, and very little access to the jobs you want that will get you to your future goals are common.
So, I dug around on YouTube a little and found some people who are in the process of getting their futures in order, and planning to come to Japan. Check these out!
Get the information you need. Shop around. There are a LOT of TESOL granting agencies out there. You need to find the one that will suit your budget and your timeline. Of course, we can help you out here in Osaka, but we are not the only ones. And to be completely frank with you, when you apply for your working visa at the Japanese Embassy, or at Immigration here in Japan, the officers in charge of your file will want to see that you are indeed a university graduate, and that you have a TESOL or CELTA or something similar that looks professional.
It may take a little more time than you bargained for to get to Japan, but you can do it. We are cheering for you like crazy on this side of the ocean. If you need someone to talk to about your process and what you are doing to make it Japan, drop me a line. I will be glad to be of service if I can.
Have a great day!
