Two questions about Karuizawa One Day Pass

Hello, I'm planning my trip to Japan and while staying in Tokyo I want to go to Karuizawa. I calculated all the buses to attractions and it looks like it's better to buy one day bus. Here are my questions:

1. Just to be sure this pass covers not only Kusakaru Kotsu and Seibu lines but also Karuizawa Aka Bus, right?

2. Where excatly I can buy one day pass at Karuizawa Station? At the tourist center? If so it's going to be problematic because the first bus starts at 9:00 and also tourist center opens at 9:00...

The Aka Bus does not seem to be covered. Here is a map of the covered lines:

I believe you buy it at the ticket counter of Shinano Railway. Their ticket counter on the 3rd floor of Karuizawa Station is open from 6:00 to 18:00. And they also have a counter in the old station building, which is open from 7:25 to 11:25.

Karuizawa is a nice city.Beside 1 day bus pass you can buy shinano railway 1 day pass=2390 seibu bus 2 day pass =2000 yen
Ueda railway 1 day pass = 1180 yen
Ueda bus 1 day pass = 500 yen
