To clarify - by IU's Japanese album do you mean the Good Day EP? That's strange because it's on the UK store too; odd that the US store lacks it.
There are a few other English language download sites than iTunes (Amazon Digital & Google Play have some KPop) but by and large iTunes is the most complete. IIRC you can also get digital downloads from Soribada but again, less choice. It might be easiest to buy the physical CD, here are a few places you can get it:
Yes Asia is a reputable site so you shouldn't have any trouble ordering from them if you choose to - I think they offer PayPal too. So yeah, at least in my experience, I use iTunes 95% of the time and then usually end up buying the physical album if it's not available on iTunes.
