This is a very nice & quiet ryokan on the way up the mountain in the Mt. Fuji/Hakone region. If you're trying to avoid the crowds down at the bottom (Hakone) or up at the top (Fujikawaguchiko), this place is for you. If you want water, it's near Lake Ashi where you can catch the sightseeing "pirate" ships. If you're looking for an onsen, there's a public outdoor bath as well as an indoor one in the bathing area downstairs (where you can soap, shampoo, etc.). NOTE: while other ryokan serve traditional bfast & dinner meals, this one does western bfast only, so be sure you have dinner elsewhere before returning for the evening, else have to order "room service" made up of canned food or instant noodles.
The staff/service are friendly and help you exchange your shoes for slippers when you enter. The only knocks (minor) I'd give are that: 1) we were told there were no extra pillows available and that they'd have to go to other rooms to take pillows from there (who ever heard of a place of lodging with no extra pillows?), and 2) while it's a short 210m/690ft walk from the Ohiradai train station, the sidewalk is quite narrow, and cars are zooming up/down the mountain, so probably not advised if you're bring super young kids or elderly parents unless you've rented a car or taken a taxi to arrive.
Other than that, it was quite the pleasant stay, quiet & peaceful, no other lodging directly next door, and a great resbit from the hustle-n-bustle of big cities like Tokyo & Kyoto.
