All known nuclear weapons created thus far run primarily on nuclear fission, with gen 2 nuclear weapons such as the hydrogen bomb using a hybrid form of fission with a limited amount of fusion. Pure fusion hasn't yet been mastered (that we know of) and doesn't cause long lasting nuclear fallout the same way fission does.
Itsreal it is Hiroshima. It was rebuilt. also remember the bombs back then where many times weaker than the nukes everyone has these days.
Is this fallout the reason for the death of the coral reefs ?
They are now flourishing; it surprised the divers.

Add to this, Japan had moved mounts and mounds of topsoil to a centralized place, the same they moved Fukushima soil when the earthquake hit
