Kawaii

This is such a beautiful song from a beautiful album.

I'm not entirely sure what the song means, but I can attempt to interpret it. Kawaii in Japanese means multiple things. While usually used to describe something "cute," it's also used to say "Lovely, dear, darling," and in some cases "to love" The song talks about freedom and a "new arrival." I can only imagine this might be a reference to Townsend's past addictions and his freedom from them being "lovely" hence the title.

The way I interpreted it just now when listening to it, was that it is about the arrival of his child. The part about freedom and losing their world, is how he and his wife lose their freedom as a child obviously takes all your attention and time. The Kawaii part is about the child itself, as kawaii can mean cute or something in that vein in Japanese, and well, a child is such a sweet thing (as long as it's not crying and screaming like crazy :P ). The arrival, new arrival, arrive safe part speaks for itself I think. The child is coming soon, and he wants the birth to go well.

Another thing that strikes me about Ghost, is how some of the songs, like this one for example (but especially Feather), sound like they could be lullabies you sing to your young kids, so that would be fitting.

Going off of what Thominator said, I agree that this is likely about the birth of his child.

As others have said the word "kawaii" is typically used to mean "cute" but it has other meanings. It can also mean "innocent" and "childlike." So I would say that his lyrics about freedom and losing their world is referring to growing older, losing your childlike and free attitude as well as your innocence, but with the new arrival the kawaii feeling will return to their lives.
