All Japanese tech and adjacent companies are so extremely corporatised. Panasonic, Toshiba, Fuji, Mitsubishi etc. They protect their profits through proprietary connectors and firmware, and the overworked Japanese populace puts up with it over there. Where it’s for an international market, that’s made clear by the fact that there’s almost never a Japanese language option (see: games and other media that protects the corporations’ IP for Japanese voice actors). Living there I was always disturbed by how the government let this happen and there was no social movement to do anything about it. The zaibatsu are still in control of the country, of course.
