Physical AI is rapidly becoming a pivotal arena for industrial competition, with Japan's significant drive in this sector stemming primarily from an urgent need. Faced with a dwindling workforce and continuous pressure to maintain productivity, Japanese enterprises are increasingly integrating AI-powered robotics into their factories, warehouses, and essential infrastructure.
The Japanese Ministry of Economy, Trade and Industry announced in March 2026 its ambitious goal to establish a robust domestic physical AI industry, aiming to secure a 30% share of the global market by 2040. This objective builds upon Japan's already formidable presence in industrial robotics, where its manufacturers commanded approximately 70% of the worldwide market in 2022, as reported by the ministry.
Through discussions with investors and industry leaders, TechCrunch investigated the forces propelling this transformation, the distinctions between Japan's strategy and those of the U.S. and China, and the potential areas for value creation as this technology evolves.
The widespread adoption of physical AI in Japan is propelled by multiple factors, including a prevailing cultural acceptance of robotics, acute labor shortages exacerbated by demographic shifts, and significant industrial prowess in mechatronics and hardware supply chains, as highlighted by Ro Gupta, managing director at Woven Capital, to TechCrunch.
"Physical AI is being acquired as a critical continuity tool, addressing the challenge of sustaining factory, warehouse, infrastructure, and service operations with a reduced workforce," stated Hogil Doh, general partner at Global Brain. He further emphasized, "From my observation, labor shortages stand out as the foremost catalyst."
Japan's demographic crisis is intensifying, with its population experiencing a decline for the 14th consecutive year in 2024. The working-age demographic now constitutes merely 59.6% of the total, a proportion projected to decrease by almost 15 million over the coming two decades, as noted by Doh. This trend is already fundamentally altering corporate operations; a 2024 Reuters/Nikkei survey revealed that labor scarcity is the primary impetus driving Japanese companies toward AI adoption.
"The impetus has evolved from mere efficiency gains to a matter of industrial survival," commented Sho Yamanaka, a principal at Salesforce Ventures, during an interview with TechCrunch. He elaborated, "Japan is confronting a tangible supply constraint where the provision of essential services is jeopardized by labor shortages. In light of the diminishing working-age population, physical AI represents a national imperative for upholding industrial benchmarks and social provisions."
Japan is intensifying its initiatives to propel automation across both manufacturing and logistics sectors, as stated by Issei Takino, CEO and co-founder of Mujin. The government actively champions automation as a solution to systemic issues like labor deficits. Mujin, a Japanese firm, has developed sophisticated software that empowers industrial robots to execute picking and logistics operations autonomously. Takino explained that Mujin's core strategy revolves around software – particularly robotics control platforms – which enhances the autonomous and efficient capabilities of existing hardware.
Historically, Japan has demonstrated exceptional proficiency in the fundamental physical components of robotics. However, whether this advantage will seamlessly extend into the AI era remains a pertinent question. Japanese venture capitalists observe that the nation maintains its strength in crucial robotics elements like actuators, sensors, and control systems. In contrast, the U.S. and China are accelerating their development of comprehensive full-stack systems that seamlessly integrate hardware, software, and data.
"Japan's profound expertise in high-precision components, which serve as the vital physical interface between AI and the tangible world, constitutes a strategic advantage," asserted Yamanaka. He elaborated, "Dominating this crucial point of interaction offers a substantial competitive edge within the global supply chain. The immediate focus is on expediting system-level optimization by profoundly integrating AI models with this specialized hardware."
Takino noted that hardware capabilities are most robust in China and Japan, with Japan exhibiting particular strength in robot motion control, while the U.S. excels in the service layer and market expansion. Traditionally, numerous U.S. firms have capitalized on their software prowess to forge integrated business models, akin to Apple, by combining powerful software platforms with premium hardware procured from Asia. Nevertheless, Takino cautioned that this established model might not be entirely applicable to the nascent domain of physical AI.
"In the realm of robotics, and particularly within Physical AI, a profound comprehension of hardware's physical attributes is paramount," stated Takino. He emphasized, "This necessitates not only strong software capabilities but also highly specialized control technologies, which demand considerable development time and entail substantial costs if failures occur."
WHILL, a startup with bases in Tokyo and San Francisco specializing in autonomous personal mobility vehicles, is harnessing Japan's "monozukuri" (craftsmanship heritage) as it pursues a comprehensive, full-stack strategy for global expansion, CEO Satoshi Sugie informed TechCrunch. The company has engineered an integrated platform that merges electric vehicles, integrated sensors, navigation systems, and cloud-based fleet management solutions for short-distance and autonomous transportation. Sugie indicated that WHILL is strategically utilizing both Japan and the U.S. for its development efforts: Japan for refining hardware and addressing the requirements of an aging population, and the U.S. for expediting software development and piloting extensive commercial models.
The Japanese government is providing substantial financial backing for this initiative. Under Prime Minister Sanae Takaichi, Japan has allocated approximately $6.3 billion to fortify its core AI capabilities, accelerate robotics integration, and facilitate industrial deployment.
The transition from experimental phases to practical deployment is already in progress. Industrial automation continues to be the most advanced segment, with Japan installing tens of thousands of robots annually, especially within the automotive industry. Furthermore, newer applications are starting to gain significant momentum, Doh observed.
"The indicator is straightforward – real customer-paid deployments as opposed to vendor-subsidized trials, consistent operation throughout entire shifts, and quantifiable performance metrics like uptime, rates of human intervention, and overall productivity impact," Doh explained.
Within the logistics sector, companies are implementing automated forklifts and advanced warehouse systems. Concurrently, in facilities management, inspection robots are being deployed across data centers and various industrial locations.
Leading companies such as SoftBank are already practically applying physical AI, integrating vision-language models with real-time control systems. This enables robots to effectively interpret their surroundings and autonomously execute intricate tasks.
In the defense sector, where autonomous systems are increasingly fundamental, competitive advantage will hinge not solely on platforms but also on operational intelligence driven by physical AI, Toru Tokushige, CEO of Terra Drone, informed TechCrunch. Tokushige further elaborated that by merging operational data with AI, Terra Drone is actively developing autonomous systems capable of performing reliably in real-world conditions, thereby contributing to the enhancement of Japan's defense infrastructure.
Investment patterns are evolving beyond mere hardware, with companies now directing increased capital towards orchestration software, digital twins, simulation tools, and integration platforms, as indicated by insights from investors and industry insiders.
Japan's physical AI ecosystem is developing along lines distinct from conventional tech disruption paradigms. Instead of a winner-take-all scenario, industry stakeholders anticipate a hybrid approach where established corporations contribute scale and dependability, while startups spearhead innovation in software and system design.
Major incumbent companies, such as Toyota Motor Corporation, Mitsubishi Electric, and Honda Motor, maintain substantial advantages in terms of manufacturing scale, customer relations, and deployment capacities. Nevertheless, startups are actively establishing crucial roles in burgeoning fields like orchestration software, perception systems, and workflow automation.
"The dynamic between startups and established corporations forms a mutually beneficial ecosystem," Yamanaka remarked. He added, "Robotics necessitates extensive hardware development, profound operational expertise, and considerable capital investment. By blending the extensive assets and specialized knowledge of large corporations with the transformative innovation offered by startups, the industry can collectively enhance its global competitive edge."
Japan's defense ecosystem is similarly transitioning from a landscape dominated by large corporations towards increased collaboration with startups, according to the Terra Drone CEO. While major companies continue to concentrate on platforms, scalability, and integration, startups are spearheading advancements in smaller systems, software, and operational methodologies, with agility and adaptability emerging as vital competitive differentiators.
Firms such as Mujin are innovating platforms designed to operate above hardware, facilitating multi-vendor automation and expedited deployment across various industries. Concurrently, other companies, including Terra Drone, are employing comparable strategies for autonomous systems, integrating AI with operational data to bolster real-world applications at scale.
"The most resilient and defensible value will ultimately reside with those who command deployment, integration, and continuous improvement," Doh concluded.
