Noticed strange cloud moving across Tokyo Sky - then 7 lights behind this which then split into V formation as moving across the SkyIt was 18:06 Tokyo time, it was a clear sky and dark, an object moved from west to east over Toyosu a man made island in the bay of Tokyo where I live. I don’t know if anyone else saw this as Toyosu is comparitively sparsely populated compared to rest of Tokyo, but I called my girlfriend straight after as I just could not believe what I had just seen. Glowing disks seemed to move behind a mist that periodically and only for split seconds 'failed' showing the lights/disks giving a twinkling effect - this is what caught my attention, you could see this slightly glowing blob moving slowly across the sky. I watched it for about 2 min until it moved out of sight over the high rise towers here. For me what is so compelling is that it morphed shape from a random scattering of white lights loosely formed into a circle to a symmetrical V shape as it gently accelerated away. From what I recall there was 7 white lights/small disks .The V shape did not fly flat like a wing but at a slowly rotating angle and rotated about 40 degrees for time I could see it.
