Photon Lab

What Photon Lab does

Photon Lab is a Japanese deep-tech venture, founded in August 2017 as a RIKEN spin-off, that develops, manufactures, and sells laser-induced acoustic inspection (laser tap) systems for non-destructive inspection of concrete infrastructure. The company's core technology, originated in the Cabinet Office SIP national project at RIKEN and QST, uses two coordinated high-power lasers—an impact laser that replaces manual hammer tapping and a measurement laser that detects surface vibrations—to remotely identify delamination, voids, and other defects on tunnel linings, bridge decks, and building façades. AI is integrated for automated defect judgment and anomaly detection, addressing Japan's shortage of qualified inspection personnel. The product portfolio spans three form factors: a road-vehicle-mounted version (priced at approximately ¥200 million per unit, already MLIT-certified and in market); a portable long-distance version capable of detecting defects from 30 meters; and a miniaturized railway tunnel version at one-tenth to one-twelfth the weight of the road version, targeted for commercialization in FY2027 under the MLIT SBIR Phase 3 grant.

The business model combines hardware sales of laser tap systems with on-site infrastructure measurement services, remote monitoring, technology consulting, and an incubation contracting layer under the proprietary 'Wood Note Method' (social implementation model) that licenses manufacturing and sales rights to SME partners while Photon Lab retains patent and productization authority. Revenue is generated from government agencies (MLIT, prefectures, municipalities), railway operators, and infrastructure inspection service companies through direct enterprise sales, MLIT Inspection Support Technology Catalog-driven public procurement, and channel partnerships with firms such as Keisoku Kensa and Construction Technology Institute (CTIE). The company holds registered entries in MLIT's Inspection Support Technology Performance Catalog for both tunnel (TN020003) and bridge (BR020016) categories, an essential prerequisite for participation in official public tendering.

As of late 2024, Photon Lab has 11 employees, registered capital of ¥136.3 million, offices in Saitama (HQ), Chiba (SBIR Development Center), Kitakyushu, Maebashi, and Kobe, and a funding base of approximately ¥148 million in equity across four rounds (Saitama Resona Bank, J&TC Frontier, Hanno Shinkin) supplemented by a ¥597.8 million SBIR Phase 3 government grant covering FY2024–2027. The company is led by CEO Kogure Shigeru (founder, former Seiko Instruments executive and RIKEN Guest Engineer), with technical leadership split between CTO Nishikino Masamoto (Laser Acoustic Division) and CTO Kawatani Satoshi (technology and planning), and operational leadership under COO Sakamoto Toshihiro, who concurrently heads the Measurement Division and is representative director of partner firm Keisoku Kensa.

Core offering

Photon Lab develops, manufactures, and sells laser acoustic inspection systems (laser tap testing devices) for remote, non-contact, non-destructive inspection of tunnel lining concrete and bridge structures. Its offerings include road-use laser tap systems, portable long-range versions for bridge inspection (up to 30m), and a miniaturized railway tunnel variant. The company also provides on-site infrastructure measurement services using its proprietary laser technology, complemented by remote monitoring and technology consulting services under its "Social Implementation Photon Lab Model."

Product overview

Photon Lab offers a portfolio of laser acoustic inspection devices designed for tunnel and bridge infrastructure assessment, complemented by on-site measurement services. The core product line includes standard road versions, portable long-range systems for bridge inspection, and compact railway tunnel variants. All devices utilize proprietary high-power laser technology developed through national research programs to enable remote, non-contact detection of concrete defects such as delamination and voids, replacing traditional hammer-based inspection methods with digitized, automated assessment capabilities.

Broad incumbents

• Leica Geosystems (Hexagon): Global provider of laser-based geospatial scanning and measurement systems (laser scanners, total stations) widely used in civil engineering and infrastructure inspection. Comparable because its laser scanning hardware competes in the same infrastructure measurement workflow that Photon Lab's acoustic laser system complements, and Hexagon owns multiple infrastructure inspection software assets.
• Shimadzu: Global Japanese manufacturer of analytical and measurement instruments (spectrometers, chromatographs, inspection systems) used across industrial and scientific applications. Comparable as a broader measurement-instrument incumbent with R&D depth in optics and spectroscopy that could extend into infrastructure sensing categories adjacent to Photon Lab's offering.
• Olympus (Industrial Solutions): Global manufacturer of industrial non-destructive testing (NDT) instruments (borescopes, ultrasonic flaw detectors, eddy current) used in inspection and quality assurance. Comparable at the instrument category level as a broader NDT/inspection equipment incumbent whose distribution and reach dwarf Photon Lab's niche laser-acoustic offering.
• Hitachi High-Tech: Japanese industrial equipment and measurement/instrumentation subsidiary of Hitachi providing industrial X-ray, CT, and analytical instruments used for non-destructive inspection and quality control. Comparable as a broad-based incumbent in industrial NDT instrumentation with the resources to enter laser-based infrastructure inspection if the market warrants.
• Trimble: Global provider of geospatial and infrastructure measurement hardware and software, including laser scanning, surveying, and structural monitoring systems. Comparable because Trimble sells laser-based measurement instruments and inspection software to the same civil/infrastructure engineering customers that would adopt Photon Lab's laser tap system.

Direct peers

• Pasco Corporation: Japanese geospatial measurement and infrastructure inspection firm with deep government relationships and asset inspection capabilities. Comparable as a domestic peer providing infrastructure measurement services to MLIT and prefectural/municipal clients using remote sensing technologies.
• Kokusai Kogyo: Japanese infrastructure inspection and surveying firm offering tunnel and bridge condition assessment services to MLIT and local governments. Directly comparable because both operate in Japan's regulated infrastructure inspection ecosystem and compete for the same public-tender inspection workloads that Photon Lab's laser tap system serves.
• Asia Air Survey: Japanese 3D measurement and aerial survey firm providing infrastructure condition assessment using optical and laser sensing. Comparable because both use laser/optical sensing for infrastructure condition assessment and serve the same Japanese public infrastructure inspection market.

Emerging players

• OPTEX: Japanese specialist manufacturer of laser and optical sensors for industrial detection and security applications. Comparable in its core competency of laser-based sensing, though focused on intrusion/security rather than infrastructure inspection, illustrating an alternate path for the underlying optical sensing technology.
• Ricoh: Japanese technology firm expanding drone-based and AI-assisted infrastructure inspection services targeting the same MLIT and local-government buyers as Photon Lab. Partially overlapping because Ricoh offers competing remote inspection approaches (drone + image AI), though not laser-acoustic, for the same aging tunnel and bridge market.
