The
Japanese Exchange Teaching program is run by the Japanese government. Each year, they take English speaking persons and ship them to Japan to teach English in schools throughout the nation. While you are not going to get rich quick ( annual salary of roughly
3600000 yen ), it is a good way to get in to Japan. Many people I know who were on JET looked for other opportunities while they were on the programme. One of my university colleagues came to Japan on JET and went on to become the CEO of a top recruitment firm in Tokyo within just a few years. He just recently bought a house for about
90000000 yen to house his newly born baby (expensive baby). He is a good example for those who do intend to initially come over on JET and move on to other things - I hope his story keeps you focused if you choose this path ^^.
And if you are wondering, you dont have to be an English native speaker. I know a few Malaysians and HK folks on the program.
