The PS2 had over 5000 titles for Japan, the USA got 2500
(this probably includes special editions and such, but still a huge difference)
In some cases I agree with you, more games should release nearer together worldwide... though I disagree with your use of "1 year later" as I don't believe any of those games were actually 1 year later, most are a few months.
Edit... it's even more skewed than I thought:
