Nintendo is looking for (part time) beta testers. The salary is pretty cheap (just 900 Yen per hour + trasportation costs and insurance) but according to this Japanese board beta testers will work on the new Mario Kart for Wii so there will be a lot of gamers who will apply for this part time job. If you are interested the working hours (Mon-Fri) from 10 am to 5 pm with one hour break for lunch.
The only problem is that you should relocate to the Nintendo city (Kyoto).
