As world populations crash, is this Japanese robot city our future?

In September 2025, Toyota officially opened Woven City at the foot of Mount Fuji: a development of streets and residents, robots and cameras, inventors and ordinary people arranged on land formerly occupied by a car factory. The company calls it a “living laboratory.” What Toyota has built is not quite a city and not quite an experiment. The city is a model, staged in domestic architecture, demonstrating that the most important question in technology right now is not whether artificial intelligence can write a poem or pass an examination, but whether it can carry a parcel, assist a frail body, and navigate a loading dock without killing anyone.

This arrangement is an example of what Japan has begun calling “physical AI.” The term has spread quickly.
