I'm sure its edible, just not a pleasant taste with its bitter tones. The deceptively thin skin layer I find is pretty tough to chew through as well. I've never seen it served sliced up with skin-on in any Asian dessert or family gathering serving. I much prefer the juicy fruit on its own! :)
There are different types of asian pears and I like the early ones with the pale skin. The later ones have a harder skin and can be less sweet if picked green for long term storage. Best time to get this is in the fall when they are harvested.
