Akari (燈)'s industrial-AI bet: Mitsubishi Electric invests ¥5B at ¥100B value
UTokyo spinout Akari bet its construction AI can power a 'next-generation industrial OS'; Mitsubishi Electric invested ¥5B at a ¥100B valuation.
Akari (燈株式会社)
What the business is
Akari (燈) is a University of Tokyo spinout selling AI SaaS and DX consulting to Japan's core industries—its Digital Billder series handles construction estimating, ordering, invoicing and cost control, with AI agents for manufacturing and logistics.
Starting capital：¥5 billion (about US$32M) from Mitsubishi Electric via a third-party allotment announced 2026-01-28—its first major external funding—at a pre-money valuation of ¥100 billion.
How it started
Founder and CEO Yuki Noro studied at the University of Tokyo, took a leave of absence to intern at an AI startup, won an excellence award in Professor Yutaka Matsuo's GCI summer program in 2020, and worked at Matsuo Institute on joint-research proposals and consulting. He founded Akari in February 2021 to bring AI to core industries; the company started with construction—estimates, orders, billing, cost control—and expanded into manufacturing and logistics.
What happened
By January 2026 Akari served customers from major listed companies to regional firms, including builders Haseko and Toda. On 2026-01-28 Mitsubishi Electric invested ¥5 billion and agreed to collaborate: Mitsubishi brings shop-floor data and control-domain knowledge, Akari brings algorithm development and software-defined-hardware practice. The goal is 'physical AI' that recalibrates robots from real operational data, toward an unmanned 'next-generation industrial OS'; at the March 2026 joint strategy briefing Mitsubishi said concept proofs were already running at three of its plants with productization targeted within six months.
How it ended up
Still running and scaling: the January 2026 round valued Akari at ¥100 billion pre-money and turned the construction-AI vendor into Mitsubishi Electric's strategic software partner for unmanned factories, with first productization of the physical-AI work targeted within six months of the March 2026 briefing.
Background
Akari (燈) was founded in February 2021 by Yuki Noro, a University of Tokyo alumnus from Professor Yutaka Matsuo's lab who had won an award in the lab's GCI program and worked at Matsuo Institute on joint research with companies. Its original bet was that Japan's core industries—starting with construction—were so far behind in digitization that an AI-native startup could own their workflows: estimates, orders, invoices and cost control.
The company built the Digital Billder suite for construction plus AI consulting (光/Hikari) and later expanded into AI agents for manufacturing and logistics, serving customers from major listed companies to regional firms, including builders Haseko and Toda. In January 2026 Mitsubishi Electric invested ¥5 billion—Akari's first major external funding—at a pre-money valuation of ¥100 billion, and signed a collaboration agreement.
The two companies framed the alliance around 'physical AI': Mitsubishi Electric contributes real shop-floor data and control-domain knowledge, Akari contributes algorithm development and software-defined-hardware practice, aiming at a 'next-generation industrial OS' for unmanned, autonomous factories. At the March 2026 joint strategy briefing Mitsubishi said concept proofs were already running at three of its plants, with productization targeted within six months.
What has to be true
- Construction was a smart first market: heavy regulation and paperwork, little AI competition, and buyers who pay for software touching estimates, orders and billing.
- Mitsubishi Electric brought what Akari lacked—decades of factory data and control engineering—so the alliance was a moat-building move, not just a check.
- Noro's Matsuo-lab pedigree gave Akari credibility with Japan Inc. and a pipeline of AI talent.
- A ¥100 billion pre-money valuation on a first major round, five years after founding, reflects Japan's 2026 bet that 'physical AI' is where domestic automation can lead.
- The deal lets Akari stay independent while attaching to a giant's distribution—fast access to factory floors without being acquired.
What can be applied
A boring vertical first: construction AI gave Akari credibility and reference customers, which is why a manufacturing giant handed it the factory floor—the alliance became the scaling engine.
Aftermath
As of 2026-03-19, Akari was scaling from construction AI into Mitsubishi Electric's physical-AI programme: ¥5 billion raised (its first major external funding) at a ¥100 billion pre-money valuation; a joint strategy announced on 2026-03-17 with concept proofs running at three Mitsubishi plants and a six-month productization target; proceeds earmarked for AI engineers and M&A of related technology. It continued to serve construction customers with Digital Billder while building toward an industrial OS for unmanned factories.
