I'm not stupid afterall

I found this Japanese IQ test, not your common IQ test. It's said to be given to job applicants in Japan.

I did solve it, and yes it was frustrating!
But I had it solved in less than 15 minutes
- I read somewhere that there's usually a time limit of 15 minutes on this test. I didn't read that till after I had solved it though.

The rules (please read them) and a link to the game can be found here:
