Gotemba to Subashiri 5th Station by taxi

Hello - does anyone know roughly how much a taxi from Gotemba Station to Subashiri 5th Station would cost, one way?

Are there usually taxis available early morning (6am)

Thank you in advance!

You should take a bus if possible. This trip by taxi could easily cost over 10,000 yen. First bus leaves at 7:35 from Gotemba station.

Sorry, looks like it will be more like 6000-7500 yen, but still quite expensive. And you will probably need to call a taxi at that time; there may not be one waiting by the station. For returning you will also almost definitely need to schedule a taxi in advance.
