If you talk about Southeast Asia region (which has been added a lot, but still lack a lot as well, show just how underdeveloped the whole region was), I would agree with you...
But if you include the whole Asia (both East and South Asia), I doubt how could you be disappointed...
While East Asia religion is still barebone, the region still has a lot of Unique Government type and a lot of flavor event...
And Japan, Ming, Manchu, and Ayuthayya (not counting the Indian Unit Pack) do have unique model so hardly only Japan...
