Shimizu Corporation
Shimizu Corporation is one of Japan's five largest general contractors, founded in 1804 in Edo (now Tokyo) and headquartered in Tokyo. It designs and builds offices, factories, hospitals, tunnels, bridges and other infrastructure in Japan and abroad, and it has long run its own construction-technology institute. In July 2026 Shimizu announced full-scale development of what it calls AI robots, or physical AI, to deal with a shrinking and ageing construction workforce. Field trials include a bipedal humanoid that autonomously patrols a construction site at 1.0 metre per second while carrying a camera, with multimodal large language models analysing the footage, and a robot arm that learns painting by imitating skilled workers. The humanoid was tested at the Tokiwabashi project, the Torch Tower site in front of Tokyo Station that is set to be Japan's tallest building. With technical cooperation from Sony and others, Shimizu is building an AI ecosystem for construction that combines site data, simulation and model development to preserve skilled-worker techniques. The robots are internal tools rather than products for sale.
💡Notable Achievement: Tested a patrol humanoid on the Torch Tower site in front of Tokyo Station, set to be Japan's tallest building.

Shimizu Humanoid
Manufactured by Shimizu Corporation
The Shimizu Humanoid is a bipedal humanoid robot that Shimizu Corporation, one of Japan's largest builders, is trialling on its own construction sites as part of a full-scale 'AI robot' (physical AI) programme announced on July 8, 2026. In a trial at the Torch Tower site in Tokyo (Tokiwabashi Project), the robot autonomously walked a pre-set route at 1.0 m/s while holding a camera, sensing and judging site conditions. Shimizu is developing it with technical cooperation from Sony and others, and plans to analyse its footage with a multimodal large language model. Shimizu has not published the robot's maker, model or specifications.

What is Shimizu Corporation?
Shimizu Corporation is one of Japan's five largest general contractors. Founded in 1804 and headquartered in Tokyo, it builds offices, factories, hospitals and infrastructure in Japan and overseas.
What is the Shimizu humanoid robot?
It is a bipedal humanoid Shimizu is testing for construction-site inspection. It patrols a pre-set route autonomously at 1.0 metre per second while holding a camera and sensing site conditions.
What does Shimizu mean by AI robots?
Shimizu uses AI robots, or physical AI, for robots that perceive and act on real sites. Its trials include the patrol humanoid and a robot arm that learns painting by imitating human workers.
Where has Shimizu tested its humanoid?
Shimizu tested the humanoid at the Tokiwabashi project, the Torch Tower construction site in front of Tokyo Station, which is set to become Japan's tallest building.
Who is Shimizu working with on robotics?
Shimizu says it is building a construction-specific AI ecosystem, combining site data, simulation and model development, with technical cooperation from several companies, including Sony.
Why is Shimizu developing robots?
Japan's construction industry faces labor shortages as its workforce ages. Shimizu wants robots to raise productivity and safety and to capture and pass on skilled workers' techniques.
How does Shimizu use AI on patrol footage?
Footage collected by the patrol humanoid is analysed with multimodal large language models to help site managers check progress and conditions more efficiently.
Who leads Shimizu Corporation?
Tatsuya Shimmura has been President of Shimizu Corporation since April 2025. The company is listed on the Tokyo Stock Exchange and employs more than 20,000 people.
