Location: The location is a large forest with a large clearing in the middle of it that has a hole in the very middle of that clearing, hidden by grass, in which you can fall through, leading to an underground cave (3 yards width, 10 yards length) surrounded by water. There are piranhas in the water that will attack if you were to fall in. It is evening/sunset while this is happening.
Jiro was training on a tree, a target set on it. He was training to improve his accuracy with his Sharingan by throwing senbon at it. He was never much of a ranged person, so this kind of training would be good for him. He decided that was enough for now and put the senbon away. He was packing up his things and was now preparing to leave.
