A government survey has found that more than 80 percent of facilities that received subsidies to build hydrogen filling stations across Japan were actually ineligible for them.

The subsidies were being offered as part of a project by the Environment Ministry for the Tokyo Olympic and Paralympic Games. The organizers of the Games have been promoting a carbon-neutral "hydrogen society," hoping to make it an Olympic legacy.

Rescue workers have found a man dead in a huge disused underground tank in Yokohama City, near Tokyo. The man is believed to be a missing construction worker in his 60s.

The man was found dead at around 5:30 p.m. on Friday in the cabin of the earth-moving machinery he was operating when he apparently fell into the tank on Tuesday evening.
