I went there by the worst ever transportation in Japan: a night bus from Tokyo, payed as a luxurious one but similar to a minivan with no space for legs, no wi-fi and not a socket there is usually to charge the phone. Avoid Maitabi (https://bus.maitabi.jp/) if you have other option, unfortunately I didn't. 
By ropeway up to Iimori Kougen station (飯森高原駅), many stone statues placed along Kurosawa trailhead (黒沢登山口). Explored other places around the area.
