Takayama to Matsumoto

Does anyone know whether there is a bus that runs from Takayama to Matsumoto in December? I am planning to travel on the 2nd December (next year) but the website I have found (http://www.alpico.co.jp/access/express/matsumoto_takayama/in...) does not specify whether or not it runs in December. However this website (http://www.hida.jp/e-koutuu/e-access/e-acc.htm) says the bus does not run December through to March.

Any ideas?

Thanks.

The bus between Matsumoto and Takayama operates around the year:

Thanks Uji. What about the bus to Shirakawa-go? I looked at their website and it doesn't say that it doesn't run at any specific time so do I assume it runs year round as long as the weather is ok? I will be travelling there early December so I don't think the weather is bad then.
Thank you

The bus from Takayama to Shirakawa-go I mean.

It also runs year around.
