SIGHTING REPORT UFO sighting at Takaido(Higashi) East, Tokyo

I am in holiday in Japan, household we rent in this occasion is a parking just infront the railway, as shown on the map, Above the railway was a floating round thing, like the ones you see in movies or internet, just it was a bit yellowish, I got to see it pretty nice, as it wasn't moving, didn't even look like it was floating, or moved by the wind(quiet windy day), it looked pretty plain, no lights nor windows or buttons, flashy things like you see in movies, just a plain gray/yellow colour

After around 15 minutes, it did exactly what mentioned above "hover and then zoom off quickly", the object which for around 15 mins in which has happend what I will add in the "any additional comments" did NOT move nor look like floating, it wasn't affected by wind, but before disapearing it hovered a hovered upwards very very slowly then just disapeared, other people who have seen this (more details after) mention seeing it go at light speed, but my son and I both saw it disapear only.

During the time it was here, people gathered, more and more local people got there all watching in silence, gasps, and whispers, wether or not this has appeared in local newspapers is unknown to me, but after the object disapeared, a train went throught the railway it was hovering just above (centimeters above it), was it chased by the train? I dont know.
