Facing a chronic labor crunch, Japan has leaned hard on automation, and humanoid machines now work everywhere from warehouses to hotel housekeeping. The problem is what happens when one fails. GMO Internet Group, through its subsidiary GMO AIR, has unveiled what it calls Japan's first mobile repair service dedicated to humanoid robots, based in Tokyo.

The economics make the case. A humanoid unit can cost between $50,000 and $100,000, and a breakdown at the start of a shift can stall an entire workflow. Shipping a robot back to a manufacturer's warranty center means days of downtime, so GMO AIR modeled its offering on human emergency medicine — an idea CEO Tomohiro Uchida says grew out of the company's own experience with failed robotic equipment.

When a fault alert arrives — a damaged drivetrain, a mechanical joint error, a software conflict — technicians drive to the scene and attempt an on-the-spot fix. If the damage proves too serious, the customer receives a replacement robot so operations continue while the ailing unit goes in for deeper repairs.

For now the service runs a single pilot van out of the company's Tokyo headquarters, with more vehicles planned if demand rises. GMO AIR engineer Shota Takizawa expects rescue crews to become indispensable once humanoids are commonplace in daily life and production, and the company sees a wider after-service market — hardware upkeep, software checks, even cybersecurity — emerging as a lucrative adjunct to the robot boom.
