Tateyama alpine route: Murado before 10 a.m

Hi.

I'm planning to visit the Alpine route on April 18th, which is weekday.

Learning from its website that the snow wall walk is not open until 10:00, so what activities can I do if I reach Murado around 8:30. Can I get access to the Panorama Road or Alps plaza while waiting or they are also open at 10:00?

Any help much appreciated!
Thank you

Where do you see it opens at 10am? It is open before 10am according to this schedule

I also noted the link you gave me. That's why got a bit confused if there is anythin to do or visit before 10 a.m.

Please suggest
Thanks

The snow corridor is only open after 10am. Here is what you can do while waiting

Thank you so much!

Since I worry about crowd, I have some questions: Is it true that it takes about 8 hrs to hike from Tateyama st. to Tateyama Mt. and to Onmachi?? I am planning to enjoy the views by doing that. If I do that, will I pass through the walk snow??

Is there bus/train from Onmachi to Kyoto/Osaka or Toyama st??

What do think if I walk through the route? Is it possible for round trip or just one way? Or it is better ro combine walking, buses and ropeway. How about the rates? Honestly, as I will be from Kyoto, I still confuse where should I start and the route... I want to finish all in one day

If you're planning a trip you go there on holiday, because of congestion, the schedule would be tight.
Both weekdays and holidays, if ride to depart last bus 17:55 from Ogisawa, you can day trip aboard the last train to Kyoto from Shinanoomachi.
