Company profile
researched Sep 2026AMATAMA Co. is a Nagoya, Japan-based deep tech company developing technology and service platforms for next-generation humanoid robots. Its stated approach combines mechanical engineering with biomechanics and neuroscience rather than treating humanoid development as a purely mechanical discipline. The company has developed two core technologies: a "Hierarchical Computer Architecture," described as a computer system optimized for humanoids, and a new "body control theory" from which it derives a simulation model.
The hierarchical computing approach connects small computers distributed throughout a robot's body in lower, middle and upper layers, each assigned a role, which together control the whole body — in contrast to conventional control systems that rely on a single computer or a few computers. AMATAMA states this design allows a significantly larger number of installed sensors, lower power consumption for control, or reallocation of that power to more advanced control processing, including foundation-model-based cognition and judgment functions. The company positions itself against a projected shortage of more than 475 million laborers by 2050 (citing the U.N.) and a humanoid market growing at a 34% CAGR from 2030.
AMATAMA was selected for the inaugural 2024 class of the Techstars Tokyo Accelerator, where it was described as optimizing hierarchical computational technology development for humanoids intended to replace labor.
Latest developments
AMATAMA announced a collaboration with fuku to accelerate research and development of next-generation humanoid robot control, applying fuku's generative AI algorithm technology and design support to AMATAMA's hierarchical computing architecture so that layer-level computers can exchange information with foundation-model AI.

Market position
AMATAMA positions itself as a supplier of a technology and service platform for humanoid robots rather than a purely mechanical robotics developer, arguing that robotics companies are confined to a mechanical engineering "silo." It cites a projected labor shortage of more than 475 million workers by 2050 and a humanoid market CAGR of 34% from 2030 as the demand backdrop.
Technology
AMATAMA's technology centers on a hierarchical computing architecture for humanoid robot control, in which small computers distributed across the robot body are organized into lower, middle and upper layers and exchange information with one another, with higher layers running foundation-model AI. This is paired with a new body control theory and a simulation model derived from it, drawing on biomechanics and neuroscience alongside mechanical engineering. Under a collaboration with fuku, the companies are working so that computers at each layer can use AI to exchange information with the base-model AI, allowing multiple control computers in a humanoid body to operate in a manner analogous to the human nervous system.
Go-to-market
The humanoid robotics industry, addressed through a technology and service platform intended to support humanoid robots expected to reach the market within a few years.
Geography
Headquartered in Nagoya, Japan; participated in the Tokyo-based Techstars Tokyo Accelerator and in events at STATION Ai in Nagoya.
History
AMATAMA has been working since August 2024 on "Development of an innovative computer system for robots using hierarchical computing technology," funded by a Go-Tech grant from Japan's Small and Medium Enterprise Agency. In August 2024 it was named to the inaugural class of the Techstars Tokyo Accelerator, a three-month, mentorship-driven program powered by JETRO and Mitsui Fudosan, with Demo Day held on November 12, 2024. Founder and CEO Yuichi Horiuchi presented at the AI Salon Nagoya event at STATION Ai in February 2025. The company subsequently announced a research and development collaboration with fuku on generative-AI-based control of next-generation humanoid robots.
