Although the summer temperatures will be around 30C along the coast, for every 200 metres you ascend there is a drop of 1C. Therefore, at 1500 metres the temperature could be as low as 20C. In the winter, the temperatures in the mountains often fall below zero at night.

The interior of Yakushima ranks as one of the wettest places on the planet. To be hiking with inadequate rain wear at high altitude is a risk not worth taking. Even in the summer it can be cold at 1500 metres. If you do not have adequate hiking gear or do not wish to bring it to Japan due to luggage weight limitations then we can arrange hiking gear rental on Yakushima. Send your sizes at least 1 week before your tour.
Even on short forest hikes we do not recommend wearing sneakers or similar footwear.
Although not technically challenging, the hike to Jomon sugi is not a walk in the park. It is a long day's hike of 22km. Similarly, the mountains of Yakushima are the highest range south of the Japan Alps. You should arrive to Yakushima in good health if you intend hiking in the mountains or some of the more challenging forest treks.
Should you not feel good during a hike then tell the guide immediately.
A lunch bento is provided on all our tours, but you may wish to pack some of your favorite snacks as you shall burn off calories on any Yakushima hike.
