Going back to cardgate, it is as if tascam EU and US operate as two different ventures or maybe they test the waters in one area before going full speed ahead everywhere? Sometimes they are a puzzle.
Quite normal for most multi-national electronics companies.
They are often structured as distinct companies, acting as independent sales outlet for the mother Corp. They all get their products from the same source, but decide what products they want to carry, what warranty terms they offer, sales and service policies, etc. Their service operations are a function of, and report to, the sales departments.
I have no direct knowledge of Tascam's corporate hierarchy, but would be very surprised if it isn't structured this way. I have worked for Japanese electronic giants most of my career, and each was organized in that way to best match local distribution channels, regulatory compliance and taxation rules
