Thanks to Prof. M S K Sir.
Yes! I too checked and found this on internet.
"The fact from Hoax Slayer:
The video was created using a fireworks simulation software tool called FWsim.
The software allows users to create their own fake fireworks “shows” complete with iconic background locations and synchronised audio.
Many commentators have pointed out that, if the display in the video was real, then there would likely be considerably more smoke in the air.
Others have pointed out that, given the apparent distance of the fireworks from the camera, the sound of the explosions would not so closely synchronise with the light.
In fact, the Mt Fuji video simulation was uploaded to YouTube by a user called hiramu55bocaboca in November 2014.
The user clearly identifies the video as a simulation and even includes the name “FWSim” in the video’s title.
So, hiramu55bocaboca was not trying to fool users into believing that the display was real.
However, since it was first uploaded, the video has been published and shared by many other users.
Some of these users may have themselves believed that the video was genuine.
Others may have deliberately implied that the video was real as a means of gaining more views."
