Tateyama Alpine Route on 30th Nov

Hello, I am arriving at Tokyo on 29 nov and wanted to take the tateyama alpine tour the next day 30th Nov, is this still possible? I have googled and it says the ticket only sold until 6 Nov. Also if anyone can help with the the best itinerary from Tokyo that would be great thank you!

It officially closes on November 30

Though portions of the route might close earlier. It is recommended you start on the Nagano side in Ogizawa. Bijodaira to Murodo is often closed the latter half of November. It also looks like the cable car is down because of repair work from the 15th to the 30th and there will be a bus instead.

Just scroll down to the Winter section to read further:
