After turning 20 a few months ago and for the past few weeks, I have been researching potential ways to move to the country for some period of time, including reading up on the Visas on the subreddit and listening to many stories and experiences moving. Like a lot of people it's a goal of mine to live in Japan, but I also want to move there due to my BIGGEST dream being to work in the video games industry.

To make my situation as clear as possible, I had to leave college for personal reasons and, unless an apprenticeship requires it, it would take quite a while for me to re-enter it. So entering the country through the JET programme would prove difficult, and I've seen a lot of talk about how receiving work without a degree is insanely difficult, though not impossible according to certain stories.

Despite that I am still specifically seeking apprenticeships and receiving help from government for that purpose, and am very much aware the visiting, let alone moving to Japan will take a long time. So I've been trying to plan out some pathways with the research I've done, but would appreciate any help.

Language School

While I've looked into various language schools through GaijinPot, I've also tried to find out how much it would cost to attend one, though not much luck. A schools I've found offer dormitories that I'd have to pay for and assistance, but it can range from four to six thousand pound depending. I'm aware that it isn't an easy way to make Japanese friends, but many stories of Language Schools talk about how they found it so easy to connect to fellow students because they were all in the same boat. Any advice on good schools and specifically an estimate of how much I'd need to save would be a massive help.

Internships

I've also found websites and services that offer overseas internships, where they assist with getting Visas. The major one being japaninternships.com, but it once again has the same issue as language school in that I don't know how much I'd need to save, with even less examples of how it could go (at least from my own research).

Working Holiday -> Work Visa

I've already mentioned GaijinPot, but I've also done a bit of research into the BostonCareersForums and their overseas programs. For this, I was hoping if anyone could give me some examples of experience with the CareersForums and if they're any good. This would probably be the longest path from my knowledge, since I'd have to acquire a lot more credentials and building up my portfolio before I could start applying to those companies, but it seems like the most ideal thing to work towards since a Working Holiday Visa would allow me to enter the country long enough to try and land a proper job, and a Work Visa would allow me to stay.

Obviously, I'm still trying to figure things out. I need to get my life on track for the next year and make some money to fund even just a trip to see if I really enjoy living in Japan.
But any advice for the things I've mentioned would be incredibly helpful.
