bus from kusatsu to karuizawa

Hi!

I've planed to visit Kusatsu in Octorber and would like to take a bus from Kusatsu to Karuizawa. Could anyone suggest me which bus and where I could catch it? I also want a bus timetable in English. Where can I find it?

Thanks!

Will you travel by the middle of October 2014?

Bus timetables for the routes between Kusatsu Onsen and Karuizawa depend on seasons.
Seibu Kogen Bus will change timetables for the route around the end of October 2014.
Kusakaru-Kotsu will use the same timbale during October 2014.

According to a bus timetable in Japanese, during 1 - 26 October 2014 buses for Karuizawa are scheduled to depart from Kusatsu Onsen (bus terminal)
at 9:00 (a), 9:15 (b), 10:00 (b), 10:30 (b), 11:35 (a), 12:10 (b), 14:00 (b), 15:00 (a), 15:30 (b) and 17:00 (a).
(a)Seibu Kogen Bus, 3880 yen, about 1 hour 40 minutes.
(b) Kusakaru-Kotsu, 2200 yen, about 1 hour 15 minutes, via Shiraito Waterfall bus stop.

The last bus will be operated by Kusakaru-Kotsu.
NOT
: 17:00 (a)
BUT
: 17:00 (b)

Dear Omotenashi,

Thanks for your help. Is the bus terminal is the same one as I take from Naganohara Kusatsu Guchi to Kusatsu Onsen or a different place? I plan to go there on Oct 21st.

I am not omotenashi. However, I'll try to answer your question.
If you're planning to go to Kusatsu Onsen from Naganohara-kusatsuguchi Station, you will want to ride on JR Bus Kanto from there, instead of Kusakaru Kotsu Bus.

In addition, Seibu Kogen Bus going through the Manza-kazawaguchi station rather than Naganohara-kusatsuguchi Station.

I think it useful to ride from Naganohara-kusatsuguchi to go to Kusatsu Onsen, because Service number is relatively large than that from Karuizawa.
