Oze National Park in mid November

Hello, I am planning to go back to Japan in mid-late November, and would like to visit Oze National Park.

From JG page I can see there are no public transportation after end of October, is this correct? I would travel from Tokyo or from Nikko.

Any help would be much appreciated, thank you!

I believe the huts and visitor centers start closing by the end of October to early November, and Oze simply remains closed for winter until May next year.
