Katekyo Search is a Japanese comparison and review website that helps families find private tutoring services for learners from preschool through high school and beyond. Visitors can explore tutoring options by region, read user reviews, and compare providers based on information such as ratings, fees, and suitability for different student needs. The site covers all 47 prefectures and also features online tutoring services for students who want to learn from anywhere in Japan.

Its listings highlight tutoring companies and organizations, including services for elementary, middle, and high school students, as well as some options for preschoolers and exam-year students. Users can review recommendations, see feedback from parents and learners, and access links to provider details and official websites. Katekyo Search also offers articles on topics such as choosing a tutor, comparing tutoring with cram schools, and assessing online lessons. The platform presents itself as a resource for researching and selecting a suitable tutor, rather than as a tutoring provider itself. It is operated by Digital Trends Inc.
