I think if a company is gonna compete on the international market, then they have to embrace at least some of the ideology that rules that system (which is neoliberalism). And the traditions of Kaizen doesn’t rule out embracing the logic of neo-liberalism. It’s not an either/or, I don’t think, as capitalism has long been effectively plastic enough to embrace a variety of variants that conform to local culture. 
Capitalism with local characteristics, in other words.
But it’s also kind of weird to imagine that Japanese culture is so static and rigid that it can’t absorb other ideologies and incorporate it in a way that makes sense locally. That was what happened during the Meji restoration, after all, seeking out aspects of western systems that they felt would work with their own culture. That’s part of how they were able to shift gears from a feudal system to a modern economy so quickly back then. It wasn’t just imposed on them, it was an active project in order to not only survive western imperialism, but to compete as an imperial power in their own right. You can see that in the postwar period, too, where they shifted from an imperial/colonial system to a modern democratic system. Japanese culture (and in fact, most cultures) is nothing if not adaptive, as they’ve show across their modern history.
