Making a videoclip in Japan as a tourist ?

I plan to go to Japan in October. This country has been on my list of favourite destinations for 10 years and my dream is about to come true!

I will take the opportunity to visit many cities such as Kobe, Nara, Osaka and Tokyo.

I am also an artist with an artistic style that blends the world of anime with traditional references and traditional music from my country.

I will probably make a video clip and content for social media. The idea is to be filmed by my friend who is a cameraman, and I will lip-sync to the music in the background.

I was wondering if Japanese people would mind if I used my speaker (without turning the volume up too high)?

Otherwise, I'm thinking of alternatives such as using headphones or a metronome.

For me, it's important to know whether Japanese culture accepts that I can, for example, film myself and use my sound appropriately without disturbing people.

Obviously, my goal is not to try to organise a flash mob in the streets of Shibuya^^.

I have already heard that Japanese people can be shocked by the behaviour of tourists who do not understand their codes, and I do not want to be one of them.
