The main reason Pearl opened it's Taiwan facility is because Star/TAMA stopped almost all of it's stencil production in 73, selling the bulk of it's contracts to Pearl. Can you imagine boosting sales by something like 400% in just a few months? The Taiwan facility, which is still open today, made some of the worst product there is, and almost killing Pearl's reputation.
So, the Japan shop, which now only builds high end stuff, kept the company alive as they took over all the cheap stuff, but it is what it is.
