How do you become one?

In Japan, many start after technical high school or vocational college and learn on the job; no specific degree or certificate is required. A finishing-skills test can prove skill, while crane or welding work may require a license.

Why does pay differ?

In Japan, pay can differ with experience, useful certificates or licenses, and the kind of machine a worker specializes in. Employer size and pay rules, location, and full-time versus shorter hours or overtime and holiday shifts can also change earnings.
