Certainly it is difficult to get a job doing the same thing a Japanese person can do, but I don't think there's any laws against it, so long as its a skilled job.
The only laws that exist are ones that say a foreigner must get a job that qualifies for a working visa, and that's just about any "skilled" job that generally requires a bachelor's degree (or higher).
Well, it was part of the 1951 Immigration Control and Refugee Recognition Act. In 1989, they loosened the restrictions somewhat, allowing some professions like entertainers and others through in limited numbers. It seems it was amended again in 2000 to loosen it a bit further.
