The mountain town of Hakone lies in the shadow of Mount Fuji and forms part of the Fuji-Hakone-Izu National Park, less than one hundred kilometres from Tokyo. As one of Japan's most popular destinations, Hakone is renowned for its hot springs, luxurious ryokans, natural beauty, and the view of Mount Fuji across Lake Ashinoko. More than just railway fans will enjoy a scenic ride on the Hakone Tozan Railway (Hakone Tozan Densha), Japan's oldest mountain railway. It winds through a narrow, densely wooded valley, stopping at small stations through bridges and tunnels. Other attractions in the area include walks to Hakone Shrine on the shore of Lake Ashi, day trips through the Hakone Open-Air Museum and explorations to Mount Kintoki to view the ruins of old Japan. No visit is complete without eating a black egg hard-boiled in the Great Boiling Valley of Owakudani. Legend has it that these eggs add some extra years to your lifespan.
