Huge silent slowly moving triangle craft in the sky over the mountains in Nikko, Japan.We're in the mountains in Nikko Japan. We were on a dark road walking back to our Ryokan.First, we both saw an orange ball moving across the sky from the horizon. We thought it was a satellite at first but it was moving too slow. I thought it might be the space station but it was too bright even for that and too slow. Then, as it moved above us, we noticed a red dot way out in front that must of been connected to the light because it moved like it was attached. The whole craft must of been the size of a football field. You could make out the shape like it was a triangle shape. It was too slow for a plane.Then my friend noticed it was turning. It pivoted, not turned like any aircraft, then moved forward again.In the end it disappeared behind the mountains.
