5. Station fujinomiya

Hi everyone, is it difficult to get a seat on the bus from Fujinomiya Station to Fujinomiya 5th Station? Are they fully booked and can I pre-book them? Is it possible to get there by taxi and how much does it cost?

Are they fully booked and can I pre-book them?

They are fully unreserved. Booking seats is not possible. As explained here:

On busy days I imagine that all seats may be taken already at Shin-Fuji before the bus arrives at Fujinomiya Station, but I am not sure.

Is it possible to get there by taxi and how much does it cost?

Yes. I think it costs around 12,000 yen one way from Fujinomiya Station.
