This is a famous football (soccer) field on the roof of a building in Tokyo from Fast&Furious Tokyo Drift

That is a Futsal field, not football. Though at core it's the same game, but futsal is small ground and there are 5 players per side. Hence small ground in the pic

the

Oh bitch please, thats famus? It doesnt even have stands nor is it a proper football stadium, thats for futsal (socer but smaller with different rules for my American friends) This is a stadium of football club Voždovac that doesnt even play any Euro leagues just Serbian first league, it has capacity for 5.1k people and is in top of shoping mall

What's the scale to a fifa legit field?

I'm pretty sure Tokyo was around long before fast & the furious.

Good luck getting your ball back
