Yakushima hike from ARAKAWA to JOMON SUGI

Dear ladies and gentlemen

We would like to hike from the Arakawa train head to Jomon sugi and probably do another trail nearby during the golden week around 2nd or 3rd of May 2019.

Is this trail only accessable by bus or is it possible to drive there for example with a hotel car?

If the access only is by bus, would you recommend to by a ticket in advance because it's in the golden week?

Are other hikes, for example in the Yakusugi area, free to access, or do we need to purchase an entry ticket?

Many thanks and kind regards
