For those who have been wondering I found a brief article on Japanese Plant production/capacity levels. Those listed below are the marked Mazda plants. The list contained all major Japanese automakers.

Plant 2002 Output Capacity
Hofu No.1 193,400 240,000
Hofu No.2 203,300 160,000
Hiroshima-Ujina 314,600 N.A.
Hiroshima-hdq 62,600 200,000

As a reminder these are general production numbers for the differnet plants and don't represent the production of any one model (i.e. this doesn't apply to the RX-8). But they do give and idea of how many cars can be produced in a year. So if somebody wants to do the math they can work out the average daily production.
