Room tour @ Yoshiike Ryokan in Hakone.
Very very pricey ($970CAD), but considering that we had our own private open-air onsen that I probably could've safely cannonballed into, it was well worth the price (even if our room was family sized and way overkill for my wife and I). We decided on this place based on Mark Wiens' Youtube video and was expecting to get the same room as him but were blown away when we realized our onsen was bigger than most public jacuzzis.
