I'm currently on my last night here and I have a question about Onsen in Hyatt. I've been to several onsens in Japan (both hotels and independently run ones) and always noticed the onsen water is murky (ranging from a little murky to very heavily sulfur smelling murky). When I got to use HR Hakone's Onsen, i was surprised to see the water is very clear, and not "smelling" of any sulfur or mineral-ish smell. So...i'm just wondering whether the water in HR Hakone is really onsen water?
