There are two ways of getting to Fuji:
Train : Tokyo > Otsuki > kawaguchiko -- Bus-- > kawaguchiko 5th Station.
Bus : Tokyo > Kawaguchiko 5th station.
U can book your return ticket in advance for the bus back to Tokyo.
For those who do not want to get committed for the return time, then you can take the train-bus return.
Bus : Kawaguchiko 5th Station > Kawaguchiko -- Train-- > Otsuki > Tokyo.
There are four 5th stations on different sides of the mountain, from where most people start their ascent to the summit:
1. Kawaguchiko 5th Station (Yamanashi Prefecture)
2. Subashiri 5th Station (Shizuoka Prefecture)
3. Gotemba 5th Station (Shizuoka Prefecture)
4. Fujinomiya 5th Station (Shizuoka Prefecture)
Most climbers start from Kawaguchiko 5th Station because its easily accessible from Tokyo. You can find lots of information on the web about how to get to all stations using bus/train. I hired a private bus, so I can't help.
Just remember there is more than one way to climb up Mt. Fuji.
