Mujin Secures $233M in Series D First Close: Advancing Physical AI and the Universal OS for Industrial Automation

Mujin raises $233M (¥36.4B) in Japan's largest startup fundraising round of 2025, co-led by NTT and Qatar Investment Authority (QIA), bringing cumulative funding to $411M (¥59.6B). Discover how MujinOS is establishing a global standard for intelligent robotics and end-to-end digital twin automation.

Mujin, a global leader in intelligent industrial automation and physical AI, has secured $233 million (¥36.4 billion) in the first close of its Series D financing. The round comprises $134 million (¥20.9 billion) in new equity financing and $99 million (¥15.5 billion) in debt facilities from major financial institutions, bringing Mujin’s total cumulative funding to $411 million (¥59.6 billion).

According to data from leading intelligence platforms including INITIAL, this financing marks the single largest startup fundraising round in Japan in 2025. The round propels Mujin’s post-money valuation past ¥150 billion ($1 billion+), firmly establishing its position as Japan’s premier physical AI and robotics unicorn.

The equity financing was co-led by NTT Group and Qatar Investment Authority (QIA), with participation from Mitsubishi HC Capital Realty and Salesforce Ventures. Existing strategic investors, including Pegasus Tech Ventures and Accenture, have also expressed strong intent for follow-on commitments ahead of the upcoming second close in 2026.

🧭 Why Series D Matters: The Transition to Product-Led Automation

Representing the largest venture financing in Japan for 2025, this round marks a watershed moment not just for Mujin, but for the global industrial automation sector as physical AI transitions from bespoke experimentation to enterprise-grade standard.

Manufacturing and logistics operations worldwide face structural headwinds: persistent labor shortages, wage inflation, and escalating supply chain volatility.

Historically, industrial robotics relied on bespoke, project-by-project system integration (SI). This traditional approach led to prolonged deployment cycles, prohibitive engineering costs, and fragmented silos between disparate equipment vendors.

Mujin is resolving this fundamental bottleneck by pivoting to a scalable, product-led automation platform model. This capital injection accelerates the adoption of MujinOS as the open, universal operating system for industrial automation worldwide.

⚡ Unpacking MujinOS: The Universal Operating System

MujinOS integrates advanced physical AI, real-time dynamic motion planning, and digital twin technology into a unified industrial architecture.

1. Multi-Vendor, Heterogeneous Fleet Orchestration

MujinOS controls and orchestrates major industrial robot arms (FANUC, Yaskawa, Mitsubishi Electric, Kawasaki, KUKA, ABB) alongside automated guided vehicles (AGVs/AMRs), pallet shuttles, automated storage and retrieval systems (AS/RS), and 3D perception sensors through a single, coherent software architecture.

2. Zero-Teaching Autonomous Intelligence (Physical AI)

Unlike traditional industrial robotics requiring weeks of manual programming and waypoint teaching, MujinOS calculates collision-free motion paths in real time. Processing rich 3D point cloud data on the fly, robots dynamically adapt to unmodeled obstacles, shape variances, and positional shifts within milliseconds.

3. Rapid Deployment and Self-Service Horizontal Scaling

MujinOS packages turnkey, high-value applications—including mixed-case depalletizing, mixed-SKU palletizing, piece picking, container unloading (TruckBot), fleet management, and Warehouse Execution Systems (WES). Customers and certified System Integrators can build, customize, and replicate automation cells across multi-site networks with unprecedented speed.

🌐 End-to-End Digital Twin for Factories and Warehouses

A central pillar of MujinOS is its real-time digital twin, bridging physical assets with digital intelligence.

Rather than a static 3D visualization dashboard, the MujinOS digital twin serves as a dynamic operational engine and living physical database:

• Granular Traceability: Real-time visibility into the exact location, movement, and condition of every pallet, tote, and item across the facility.
• Proactive Bottleneck Resolution: Predictive monitoring spots conveyor back-ups or starvation states before they occur, dynamically rerouting AGV traffic and optimizing picking sequences.
• Risk Mitigation & Simulation: Accurate forecasting and scenario simulations empower data-driven decisions on throughput tuning and capital expenditures.
