Japan is looking at installing toilets in elevators and providing an emergency supply of drinking water for people trapped by the nation’s frequent powerful earthquakes, an official said Wednesday.



The move comes after dozens of people were left high and dry, some for over an hour, after a 7.8 magnitude quake on Saturday that stopped lifts.

Most of the elevators automatically stopped at the nearest floor and opened their doors, but 14 were stranded between storeys.

A meeting between officials from the infrastructure ministry and elevator industry bodies agreed to look into providing toilets for emergencies, an official from the elevator makers association said.

These might include collapsible cardboard structures with a waterproof bag or absorbent material inside.

Some new lifts have small seating areas for Japan’s growing ranks of elderly people, and installing facilities underneath the seats is a possibility.

Japan has about 620,000 elevators in public or commercial buildings, about 20% of which are in Tokyo.

It also sits at the junction of four tectonic plates and is regularly hit by powerful earthquakes.

The government estimates that the next “big one” – a huge quake seismologists say is almost certain to hit the capital over the coming decades – may leave up to 17,000 people stranded in elevators.

Saturday’s quake was centred on a remote spot in the Pacific Ocean about 900km (550 miles) south of Tokyo, but was felt throughout the country.

Twelve people were injured, including a 56-year-old man who broke his ribs, but no one was killed, according to the Tokyo fire department and local media.
