Japan’s famously conscientious but overburdened baggage handlers will soon be joined by extra staff at Tokyo’s Haneda airport – although their new colleagues will need to take regular recharging breaks.

Japan Airlines will introduce humanoid robots on a trial basis from the beginning of May, with a view to deploying them permanently as a solution to the country’s chronic labour shortage.

The Chinese-made humanoids will move travellers’ luggage and cargo on the tarmac at Haneda, which handles more than 60 million passengers a year.

JAL and its partner in the initiative, Japan Airlines GMO Internet Group, hope the experiment – which ends in 2028 – will lessen the burden on human employees amid a surge in inbound tourism and forecasts of more severe labour shortages.

In a demonstration for the media this week, a 130cm-tall robot manufactured by Hangzhou-based Unitree was seen tentatively “pushing” cargo on to a conveyer belt next to a JAL passenger plane and waving to an unseen colleague.
