One of those places that magic you away from the rest of the world.
Incredible views of clouds over mountains, forests, cliffs and heaps of deer and monkeys.
A car is a must!
I recommend the travel company YES Yakushima. They make everything very easy and will organise your car, ferry and accommodation if you want it (free service). The car through them was $350aud ishh for 5 days.
We spent 5 days, did the Jomon Sugi hike and part of the Shiratani Unsuikyo trail, do Jomon Sugi but don't underestimate it.
Food around is great when the restaurants are open, very friendly and helpful locals. Also recommend the kayak tour!
