Don't bother with GABA or Interac or Borderlink. You won't make enough money. The recent thread where people are saying they have to stop paying the monthly school lunch fee and bring cup of noodles because they are too poor is eye-opening
10-15 years ago, Interac MAY have been a viable alternate when they paid around 250,000 and inflation was lower. (JET paid around 300,000 10 years ago)
Today, Interac pays around 200,000 AND inflation is noticably up. JET pays around 330,000
You won't have fun coming over here unless you're a JET. You'll be too poor to travel, date, eat out etc. You'll be impoverished and can easily get trapped.
JET pays enough to enjoy Japan as an experience. You won't be rich, but you won't be impoverished and you can at least have a proper lunch and have enough to explore/experience Japan.
If you don't get into JET, try again next year or come to Japan on vacation. The "foot in the door" is a myth too
