Asian jpop fans: So how is...?

[Eigakan]

How is jpop viewed in your countries (I'm talking about Singapore, Malaysia, Phillipines, Taiwan, Hong Kong, etc.) is jpop really mainstream, can you actually watch PVs on regular TV channels and radio, alongside with the artists from your country and western acts, or is it something that's very limited and the only way to watch or listen to them is by buying their albums, do you have domestic releases? (I know that Taiwan and Hong Kong do). So in general how is the jpop scene in your country?

Thank you for your answers in advance.
