Izukyu Shimoda to Kawaguchiko station

Will travel between Izukyu Shimoda to Kawaguchiko station 29 august 2014. Which is the simplest and fastest way?

It requires about 5 to 7 hours to travel by rail.
A fastest route is not always a simplest route. 　
Please note that Izukyu trains run between Izukyu-Shimoda and Atami only infrequently.

A route partly by Shinkansen:
Izukyu-Shimoda -- Atami -- Shin-Yokohama -- Hachioji -- Otsuki -- Kawaguchiko.

Izukyu-Shimoda -- Atami -- Yokohama -- Hachioji -- Otsuki -- Kawaguchiko.
