Visit Oze national Park this week

Would like to visit Oze National Park this week. Is there any public transport from Numata or Katasinge Village to either Hatomachitoge or Oshimizu. Google maps shows road is closed other forums i read 1 bus per hour. If road is closed from Katashina van I run on this road. Cheers

The bus to Hatomachitoge starts running from April 19:

(And the road is not opened to regular vehicles the entire year this year.)

And the buses to Oshimizu start running from April 20:

(However, the road there already reopens in the morning of April 12, so you could go there with a car.)
