Yeah, it's hard to get info on them from a search engine because there are conflicting reports; I even found a recipe for honeysuckle jelly! I'm not sure what species these are, but they are definitely not Japanese. They might be Morrow's honeysuckle.
I found one interesting bit of info; apparently where cedar waxwings consume large quantities of them the tips of their tail feathers turn from yellow to orange because of pigments in the berries!
