About ItoKuro

ItoKuro Inc. is a Japanese technology company that operates a portfolio of vertical media websites focused on the education sector. Founded on March 30, 2006, by Hirokazu Ito and Takeshi Kuroiwa, the company name is a portmanteau of its founders' surnames. Manabu Yamaki, formerly of Recruit and Kakaku.com, joined in December 2006 and later became the CEO, shifting the company's focus towards education-related media. ItoKuro achieved a significant milestone with its listing on the Tokyo Stock Exchange Mothers market in July 2015.

The company's business model is centered on its performance-based billing system. It operates several major portals, including "Juku Navi," a search and comparison site for cram schools and preparatory schools, which is considered the number one portal in its domain in Japan. Other key sites include "Minna no Gakko Joho" for school information from kindergarten to university, "Kateikyoshi Hikaku Net" for private tutors, and "Kodomo Booster" for children's lessons and activities. ItoKuro generates revenue when users request information or enroll in services through its portals, receiving compensation from the client schools and educational institutions based on these results. This model provides a cost-effective marketing channel for educational service providers.

ItoKuro primarily serves parents and students in Japan seeking educational services, and its clients are the educational institutions themselves, such as cram schools, private tutors, and other schools. The company has grown through a combination of organic development and strategic acquisitions of other media sites, consolidating its position in the educational information market. In addition to its media services, ItoKuro also provides consulting services, supporting the marketing activities of its clients.
