Kudan

Kudan is a spatial perception company headquartered in Shibuya, Tokyo, and listed on the Tokyo Stock Exchange Growth Market under the code 4425. It began in 2011 as Kudan Limited in Bristol, building computer vision for augmented reality, and set up Kudan Inc. in Japan in 2014 as the group headquarters. The company moved into SLAM in 2016, listed in 2018 and acquired the Munich SLAM developer Artisense in 2020. It sells localization and mapping software, autonomous navigation packages for mobile robots and digital twin products.

Kudan PRISM, short for Photo-Realistic Integrated Spatial Management, is the digital twin platform. It launched on August 14, 2025 as the successor to the company’s Digital Asset Management Solution and combines 3D Gaussian Splatting with Kudan’s own spatial perception algorithms. A site is reconstructed as a photorealistic splat, then equipment records, drawings, inspection history and IoT sensor data are attached to positions inside it. Kudan lists eight functions, which include semantic spatial understanding, change and difference analysis between past and present models, construction and layout simulation, predictive risk analytics and CAD and BIM integration.

PRISM Cloud launched globally on February 13, 2026 as the browser version. It needs no installed software and runs on PCs, tablets and smartphones. Splats and point clouds are held centrally, and users add annotations, notes and linked documents in 3D space. Kudan supports public cloud hosting on AWS and Azure, private cloud and customer managed configurations, an API for CMMS, ERP and IoT systems, and an interface in Japanese, English and German. PRISM Local, which the February 2026 release called PRISM Edge, covers closed networks as a Windows application.

Capture is handled through a collaboration with XGRIDS. Kudan offers the XGRIDS Lixel K2, PortalCam and Lixel L2 Pro scanners through its own site and has added the Lixel L3 to its Japanese lineup, and PRISM takes data from handheld, drone and robot mounted capture. Kudan also builds V-MMS, a vehicle mounted mobile mapping system that outputs colorized and semantically segmented point clouds.

PRISM is priced as an initial setup fee plus a SaaS subscription, with optional packs for AI analysis, API and system integration and additional users, and no figures are published. Kudan also offers the technology under licensing agreements. PRISM e-Road, a road maintenance version built on PRISM, is in joint development with NEXCO-East Engineering, and a September 2026 release says the two companies are preparing to launch it as a service.
