'Again, again, again!" shouts my 4-year-old daughter. "I don't want to leave! Let's stay forever!" her elder sister, aged 6, yells for good measure.

Maybe it's the white powder snow, the brilliant blue skies and the picture-book perfect views of craggy mountains that surround us — or maybe it's the thrill of skiing down a slope on their own for the first time. Whatever the reason, my daughters — eyes bright and cheeks flushed — are smitten.

Their enthusiasm was perhaps understandable, given how smoothly our ski trip unfolded during a recent weekend visit to Risonare Yatsugatake, a resort hidden among the mountains and forests of Yamanashi Prefecture.
