Bus to Mashuko in Hokkaido

Hi,

I'm going to Hokkaido in a few weeks and am planning on staying in Teshikaga. I was wondering if there is a daily bus from Teshikiaga that will take me to the observation decks for Mashuko, and from there take me to Kawayu.

I found this: http://northern-road.jp/navi/eng/Lake_Mashu_Traffic_Restrictions.pdf

But it seems that it is only for June, and I will be there middle of October.

Thanks
Tam

Public transportation around Akan National Park is generally very bad. In October there are four round trips per day between JR Mashu Station (in central Teshikaga) and the lake. Departures are at 8:55, 10:30, 13:30 and 15:35. You will have one hour at the observation deck before the bus returns to Mashu Station.

Be careful! The bus service might not run after October 11:

Oh darn, I guess I will have to skip this then. We won't be in Teshikaga till Oct 14th. And I heard taking a Taxi is really expensive.

Thanks for the help Uji!
