To go straight to the nitpicks:
> The Matrix Trilogy, Ghost in the Shell, [...]. Except Gibson did it first.
Ghost in the Shell started publication around 1989, but it's author was writing cyberpunk in 1985 (Appleseed), with already many of the themes approached in it.
1985 is a tad later than Gibson's Neuromamcer, but given the timeline to start a series with the level of details Masamune Shirow uses, they're basically writing at the same time.
I wouldn't put Gibson as a direct influence, and in the Japanese scene Akira, started in 1982 would be way more influencial.
What really stroke me is how far the Japanese culture feels from a western perspective, when it had a very flourishing Cyberpunk scene that doesn't get much credit outside of manga/anime fans.
