One thing I've learned over the years is that isn't easy to find decent material on Asian art traditions outside the confines of a university or museum, and this is true whether we're talking online or in traditional book form. Try to go beyond facile Wikipedia articles or introductory coffee-table volumes on a topic such as, say, Chinese ink painting or Japanese lacquerware, and you quickly run into nothing but frustration, whereas even individual Western artists like Donatello, Veronese and Fragonard have any number of richly illustrated, scholarly volumes detailing their lives and work. The difference here is not due to anything innately superior in the Western artistic tradition - as anyone who has bothered to learn about Asian arts will attest - but the result of a self-perpetuating legacy of centuries of Eurocentrism, under which the assumption that there is little worth learning about the artistic traditions of other peoples serves as justification for failing to investigate further, the resulting ignorance then being seized upon as "proof" of the initial assumption.
To put it simply, there is a tremendous wealth of highly informative material here, put together by real scholars, and - unlike most things on the web nowadays - this is all done free of any apparent motivation to somehow squeeze a buck out of the audience. If you remain ignorant of Asian artistic traditions after being exposed to this high-quality material, the only target for blame will be your own distraction or disinterest, rather than a lack of good sources to learn from.
