Maybe he/she meant the Hakone Ropeway as described below:
"The Hakone Ropeway, covering a distance of 4,035 m between Sounzan and Togendai, is the longest in Japan and the second-longest in the world after the Kriens Bahn in Switzerland. Gondolas carrying 13 passengers rise up into the sky once every minute. Enjoy sweeping panoramas all the way over the sea of trees from Sounzan to Togendai near Lake Ashi, via Owakudani and Ubako. At its highest point, between Sounzan and Owakudani, the ropeway is 130 meters above the ground. The large crater visible below is impressive in its overwhelming energy. Proceeding to Ubako and Togendai, the ropeway offers grand views of Lake Ashi and Mount Fuji behind Mount Kami, with the scenery reflecting the changes of the seasons. The journey between Sounzan and Togendai takes approximately 28 minutes. The Hakone Freepass is an economical and convenient way to enjoy an excursion in Hakone using the Hakone Ropeway."
