「Spent a night here during winter in Hakone on a solo trip and had a beautiful time. The old innkeeper lady didn't speak any English but she was extremely nice and friendly and made my time here very enjoyable. I was able to get by with basic Japanese (and they had a good instruction sheet in English, so you'll be fine), or use Google Translate with the free WiFi! Perhaps because of this, I only saw Japanese tourists!
Very atmospheric and nice Ryokan tucked away by a bridge just about 5 mins...
