What is Cotoyogi?
Cotoyogi is the Center's AI crawler. Cotoyogi is a web crawler operated by the Center for Research and Development on Data Lake, ROIS-DS (Research Organization of Information and Systems - Data Science) for collecting Japanese language data resources.
Cotoyogi matters for AI visibility because the pages it collects can shape what large language models learn about your brand, products, and expertise. Allowing it can strengthen how accurately AI systems describe and recommend you, while disallowing it keeps your content out of training data. Either way, knowing Cotoyogi visits is the first step to managing how your brand shows up in AI search.
Tracking which AI crawlers and agents reach your site, and what they do once there, is the foundation of generative engine optimization. See our guides to AI crawlers and robots.txt to control automated access and protect your AI search visibility.
