Climb, swing, balance and trek along the tree-tops with the opening of NAC's new adventure park in Niseko this coming winter.

Construction work on Japan's largest adventure centre.

With construction still underway, the park will offer great outdoor fun with features including suspension bridges, high ropes, vertical drops and zip lines – the longest of which is almost 100 metres.

The park includes six courses in total with four of them designed for beginners so its perfect for the whole family. Standing platforms are positioned at both four and eight metres above ground level so you can try a little higher if you want an extra challenge.

To ensure the utmost safety, the park will feature a French-engineered safety-line system whereby participants remain attached to the course at all times. Only with the assistance of staff can participants pass-by others on the course or be brought safety off the course.


The park is conveniently positioned in the forest adjacent to the soon-to-be-finished, new Ace Family Quad Lift at Grand Hirafu. With a width of only 45 metres, the park extends all the way from nearby Aya Niseko to almost as high at the Hotel Niseko Alpen.

The 3-year project, which has been in construction since September, is well on its way to completion with a team of 16 tradesmen from Estonia. NAC are aiming to open the park on Japan's Culture Day national holiday weekend in early November.
