Arakurayama Sengen Park to Yeti Resort

Is it doable in 1 day itinerary going to Arakurayama Sengen Park, Yeti Resort then last Gotemba. We are located in Hatagaya Area. Is the Itinerary will consume too much of travel. Please enlighten me. Thank you.

Yeti has few choices. You would have four hours at Yeti.
Gotemba 1235-1318 Yeti 1723-1818 Gotemba

Then, you would need to leave Kawaguchiko at 1100.
Kawaguchiko 1100-(Fujisan station 1108)-1215 Gotemba

You could get to Kawaguchiko by the first Loop Bus. Or, you could ride on the 10:38 bus at Fujisan station.
Chureito Pagoda 947-(Fujisan station 1024)-1032 Kawaguchiko

You could walk to Arakurayama from Shimo-Yoshida station. The earliest connection requires you to take the 4:59 train. Then, you would have two hours near Arakurayama.
Hatagaya 459-608 Takao 614-651 Otsuki 702-743 Shimo-Yoshida

Sightseeing time (2+4 hours) would be just 50% from 6:00 to 18:00 (12 hours).

Thank @luisjp

Earliest possible ride would be via train only right? I check on bus availability but the seats on early schedules are fully booked.

From Shimoyoshida Uppn checking we can get to Mt Fuji Station by train worth Y220 rather than taking the unlimited bus ride.

And additional info please how can we pay the bus rides from Mt Fuji Station-Gotemba Station, using IC card is possible?

Thanks for the prompt reply, really a big help!

I used Google Maps, but Jorudan gives the same. Three trains from Hatagaya to Shimo-Yoshida. Do adjust the date of the travel.

It costs 220 yen from Shimo-Yoshida to Fujisan.
https://world.jorudan.co.jp/mln/en/?p=0&xpd=1&from=Shimo-Yoshida&to=Fu...
Or, 0 yen. I mean a walk from Arakurayama direct to Fujisan. Google Maps estimates the direct walk for 39 min, or the 220 yen train course for 26 min (with a 21 min walk). Or, the no walk bus course with the 1,030 yen.
