Japan is also a convenient 'bridge' of what is commonly categorized as Western culture and Eastern culture. This is somewhat by their own design, and has a long history given both their own Westernization efforts from their infamous imperial days and post occupation. That gives them a unique niche of exotic and yet somewhat comfortably familiar so that it more often feels 'weird' but not necessarily 'alienating'.
China is the new kid on the block in comparison, even if China was a robust democracy they would be at a disadvantage in cultural propagation from this. They try to promote some of their own cultural products but a dictatorship self-sabotages anything too good or popular having a deliberate chilling effect.
Korea as a third culture makes a decent comparative reference. They are 'newer' culturally than Japan (in terms of widespread western cultural exposure) but South Korean music, film, and TV are growing and more evident among younger generations. There are some western Manhwa fans but it is still more niche.
