What It Is

Technohighway Co. is a technology company based in Tsukuba, Japan, focusing on image processing, sensing, and cloud services for environmental, infrastructure, and equipment maintenance management. For the developer tools category, its most relevant offerings are the C2finder web service and WebAPI for automatic crack and free-lime detection, as well as GigaScope Community, an application that assists with damage-map creation and can handle extremely large images.

Core Capabilities

GigaScope Community supports smooth viewing and editing of images ranging from small files to gigapixel-scale imagery. It can directly display orthophotos of bridges and tunnels, with zooming, panning, drawing, and damage-map organization features. Output formats include JPG, DXF, CSV, and SVG, making it suitable for integration with CAD workflows or downstream data processing. The stated operating environment is Windows 10/11 64-bit, with at least 8GB of memory and 16GB recommended.

On the web service side, users can upload images through a browser for automatic crack detection. The WebAPI allows enterprises to call the automatic detection function from their own systems or standalone applications. C2finder is listed in Japan’s Ministry of Land, Infrastructure, Transport and Tourism inspection support technology performance catalog. The site also states a detection accuracy of 95% mAP for cracks and free lime, and a processing speed of about 4 seconds for images around 5000×3600 pixels.

Pricing and Integration

Public pricing information is limited. The site only states that the crack detection WebAPI uses pay-as-you-go billing and has no initial fee. At the API/SDK level, the official site confirms that the WebAPI can be called from external systems, but it does not provide interface documentation, authentication details, sample code, SDKs, rate limits, or SLA information. In terms of ecosystem, the company has project cases with several Japanese infrastructure inspection companies, and also supports custom development such as multi-camera systems, LiDAR-based pothole detection, and real-time WebGIS visualization.

Pros, Cons, and Who It’s For

Its strengths are a very clearly defined industry focus and a set of capabilities built around bridge, tunnel, and road inspection, including applications, web services, APIs, and hardware system development. GigaScope is also practical for working with large orthophotos and producing damage maps. The downsides are limited public developer documentation, weak internationalization, opaque pricing, and desktop environment information that only covers Windows.

It is best suited to infrastructure inspection companies, civil engineering maintenance organizations, and development teams that need to embed crack recognition into their own inspection platforms. If the requirement is general-purpose CV annotation, model training, or open-ended MLOps, Roboflow, Label Studio, Supervisely, or a self-built OpenCV-based solution will be more broadly applicable.

Access from China

The official site and mihari.net do not disclose accessibility from mainland China, supported payment methods, or service coverage, so these remain unknown. For deployment in China-facing projects, network connectivity, cross-border data transfer, Japanese-language support, invoicing, and payment methods should be confirmed separately.
