What Mamoru does
Mamoru (株式会社マモル) is a Japanese private company founded in July 2018 and headquartered in Shinjuku, Tokyo, that develops and operates Mamorepo (マモレポ), a cloud-based bullying and harassment reporting and consultation platform for schools and educational institutions. The platform supports early-stage detection of bullying incidents and structured response workflows, is sold on an annual subscription basis to schools and school corporations, and has been recognized by Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT) as part of the COCOLO Plan for bullying and truancy consultation systems; the company holds a patent on the platform technology. In October 2025 the company extended its platform into the corporate market with Mamorepo biz, an external whistleblower hotline service compliant with Japan's Whistleblower Protection Act and explicitly targeting IPO-preparing and growth-stage enterprises, distributed via annual subscriptions. Beyond its core SaaS products, Mamoru monetizes through professional services that include SNS literacy seminars for schools (covering platforms such as BeReal, Instagram, TikTok, and LINE), corporate harassment and psychological-safety training, and education content development (including the free Connect Hearts parent-child bullying-prevention program), supported by DX consulting for educational settings using its public-sector and academic networks. The company reaches 101–250 employees, pursues direct enterprise sales with no resellers or marketplace listings, and has built research collaborations with Tokyo University of Science, the Japan Psychological Association, and AIST to anchor credibility with public-sector and institutional buyers.
