Get a Job in Japan
Here’s the method I used for getting a job in Japan that was quite successful. After three interviews I had offers for four positions. Please realize, also, that most jobs acquired by foreigners in Japan are English teaching positions.
Side note: Having a bachelors degree is almost a must in order for the Japanese Immigration Office to grant you a visa.
Hopefully these steps help you also.

3 Apply Everywhere
Not mentioned in the video but added by RisuMiso in the comments is perseverance. Most people will probably get rejected many times before finding a job. This is normal. You may also get interviews, second interviews, and still have it fall through. Keep on trying, and you will find a job.
