Takumi Nakamura, the other man lost in Aokigahara, is likely to be a manifestation from the spirit of the body found in the tent. He claims that he doesn't want to die anymore and just want to see his family. That may be a reference as well an explanation to the person in the tent's death: the person in question went to Aokigahara to commit suicide, but he decided he didn't wanted to die anymore, since a walk-talkie is found near his body, implying that he got lost in the woods and was trying reach for help. Those events matches Takumi's situation, since when he's first seen in the movie he is trying desperately to leave the forest. When Takumi and Arthur are about to leave the tent, Takumi dies. The reason of his death may be because the tent was the place he was alive and also died, so his spirit can't go any further.
