Bus timetable around Lake Tazawa

HELLO EVERYONE :)
I come to lake tazawa in april. I saw in the page of lake tazawa in the japan guide (http://www.japan-guide.com/forum/quereadisplay.html?0+116737) that there are 6 buses a day around the lake.
I tried to find the timetable of the bus but did not find.
do you know where can I find it? also, do the buses work all year?
and where can I find timetable for the bus from Tazawako Station to Tazawa-kohan bus stop ?

by the way - I come before the 26 april so she ship is not an option (it start just at 26 april).

thanks a lot!

Here is the timetable:

And a simple bus map:

They seem to run everyday of the year except the red colored one which does not run on winter weekends.

The buses start from Tazawako Station and then stop at Tazawa-kohan bus stop before circling the lake and returning to Tazawako Station. There are a couple of other buses per hour on the section between Tazawako Station and Tazawa-kohan.

thank you ver much! do you know what every column mean? unfotunately i do not understand japanese :( what column is lake tazawa ?

That's why I posted the bus map. It allows you to compare the names with the locations.
田沢湖駅前 Tazawako Station
田沢湖畔 Tazawakohan
御座の石 Goza no ishi
潟尻 Katajiri

Also refer to the following English maps:

thanks a lot! just one last thing - do you know what is the name of the station of the Tatsuko Statue?

The bus stop for the Tatsuko statue たつこ像 is Katajiri 潟尻. The statue is just a short walk across the road by the shore.
