From Osaka to Kawaguchiko?

How can I get to Kawaguchiko Staion from Osaka? Prefer to ride in train.

There is a shcedule revision on the Shinkansen on 15th March 2008.
I list Hikari departures from Kyoto, but all Hikari leaves Shin-Osaka 16 minutes earlier than Kyoto.

1) Optimal connections valid until 14th March:

Kyoto 7:22am--Hikari--9:29 Mishima 9:40--Bus--11:50am Kawaguchiko Station
Kyoto 9:35am--Hikari--11:29 Mishima 11:40--Bus--13:50 Kawaguchiko
Kyoto 11:35am--Hikari--13:29 Mishima 14:00--Bus--14:50 Gotemba 15:10--Bus--16:25 Kawaguchiko
Kyoto 13:35--Hikari--15:29 Mishima 15:40--Bus--16:30 Gotemba 16:40--Bus--17:50 Kawaguchiko (Saturdays and holidays)
Kyoto 13:35--Hikari--15:29 Mishima 16:00--Bus--16:50 Gotemba 17:10--18:20 Kawaguchiko (weekdays)
Kyoto 15:35--Hikari--17:29 Mishima 17:40--Bus--18:30 Gotemba 18:50--20:00 Kawaguchiko

2) On and after 15th March:

Kyoto--Shinkansen Hikari--Mishima--bus--Kawaguchiko
7:45--9:55/10:05--12:25 (change buses at Gotemba)
9:56--11:55/12:40--14:55 (change buses at Gotemba)
11:56--13:55/15:05--17:25 (change buses at Gotemba)
13:56--15:55/16:10--runs only on Saturdays and holidays--18:20 (direct)
13:56--15:55/17:10--runs everyday--19:20 (direct)
15:56--17:55/19:00--21:10 (direct)

The price for the bus from Mishima to Lake Kawaguchi is 2,130 yen. You should buy a ticket before you board the bus at Mishima, especially when you need to change buses at Gotemba. Otherwise they charge you for each segment, which results in the higher price.
