In any case, Toyota / Lean / etc. is a mindset that has a lot of really good ideas embedded in it. I'm sure you can take it and distort it and come up with a monstrosity (like people do with "Agile") but the core stuff is really good.
As noted by lemax, The Machine That Changed The World is a really good book on this topic.
It's also interesting to note that a lot of the "Toyota" system was inspired by the teachings of an American, W. Edwards Deming. If I recall the story correctly, Deming was pushing these ideas on statistical process control, and nobody in America would listen to him, so he want to Japan and they embraced his stuff, ran with it, and it helped them become a manufacturing juggernaut.
