First Sighting - At about 7p.m., I was riding my bicycle to my friend's house on my usual route I ride to get there. I was riding on this narrow piece of path getting to the top of a small hill when suddenly I saw something coming quick from behind me to flying above me. Caught it from my peripheral vision above me and tracked it in front of me until it went behind a tall house in front of my path. Again, this object was moving quickly plus it was already dark outside so difficult to see. It was a good height in the night sky, perhaps a low flying airplane height (can't really determine how far away it was because of the night, speed of the object, and my shortcoming to give approximate distances). The object had two sets of elongated lights on the front half and back half that both flashed/pulsated approximately three times before it went out of my view. Due to the position of the elongated lights in the front and back half of the object, I am assuming that the object was cylindrical in shape. Object made absolutely no sound whatsoever though I wish it did so my attention would have been focused on it longer and maybe got a better view of it. Second Sighting - After witnessing the cylindrical object and since I had just reached the top of a big hill, I raced in the direction of where the previous cylindrical object went to. I was only about 100 meters or so from a good viewpoint on top of the hill that opens up and lets me see out and down into the distance overlooking my area (Kaminagaya Ward/Kounan Ward). When I looked out into the distance, I saw bright lights "hovering" in a reverse triangle pattern at first. All three were bright and seemed to stay in that position for about 5 - mins. After that, the upper left light point started slowly moving away from the other two light points to my left (or perhaps to the West.) As it moved out, the bright light object became darker and darker. Then, the upper right light point started doing the same thing; move away and got darker little by little. Just left the one light object there that was still the same brightness there as the other two moved away. After another 10 mins, I knew I had to go because I was already late in meeting my friend and the show seemed to be pretty much over anyway.
