I have met Aki Sasaki, President of Tomei and have had the pleasure of dinner with him in 2012.
Tomei take their manufacturing very seriously and are all about quality control, regardless of the country they are made in. It is not as competitive to make everything in Japan like they used to. With approx $200 million of stock in the USA, they need to ensure that things are made and sold at competitive margin. The chinese are brilliant manufactures, but are 100% clueless as to what they make and why it has to be a certain way. I have visited factories and facilities you get good and bad facilities depending on the operators. The good facilities have engineers as owners. The bad ones have people looking to copy and make a quick buck. The only way you can tell is if you go to the factory and have a good look around at their manufacturing. Wages for good manufacturing employees are around $100-$150 USD per week, 40hr work week, paid overtime etc and includes boarding / meals etc. Graduates that work at HSBC or similar in accounting / auditing roles - approx 700-800 usd per month, paid monthly as a salary and lots of overtime when required.
