The "vision of a hydrogen society where hydrogen is used in every sector" is probably motivated by a desire to become technological leaders in this field. Japan has fallen behind in battery technology, and Toyota was an early leader with its hybrid vehicles, but when it comes to fully electric cars, Japanese car makers are also falling behind. So I suspect they are trying to find a niche where they can develop technologies that they can maybe export later. From that point of view, where the hydrogen is coming from is not that important. And: a battery electric car is also not really helping to "save the planet" if the electricity used to charge it is coming from a coal plant...
