SoftBank has launched "Mentari," an AI service for schools. It helps teachers manage student mental-health surveys and detect urgent issues.
A chat character called "Mofu" listens to students.
The service is free initially and began on August 27, 2026.
What happened
SoftBank Corp. began offering a new service called "Mentari" on August 27, 2026, for elementary, junior high, and high schools. The service uses AI to help teachers support students' mental health and is free for an initial period to verify its effectiveness.
Why it matters
Schools regularly run surveys on issues like bullying but face heavy workloads from paper-based processes and a shortage of school counselors. Mentari centralizes survey creation, collection, and analysis, and its AI flags urgent concerns to teachers. It also includes an AI chat character called "Mofu" that listens to students and helps them articulate their worries.
What to watch
The AI chat is specifically designed to only listen and organize content, not give advice that could influence students' decisions. For teachers, the system provides advice on similar cases and response methods supervised by experts and psychiatrists, which could help less experienced teachers handle student consultations.

This launch comes as schools in Japan follow the Ministry of Education's basic policy on bullying prevention, which requires regular surveys. The press release points to a specific problem: paper-based surveys create heavy workloads, and there aren't enough school counselors to support every student. Mentari is designed to address these pain points directly. Its value proposition appears to be in the early detection of students who need help, which is meant to free up teachers' time for more face-to-face support rather than replace human interaction. Interestingly, the design explicitly limits the AI's role to listening and organizing, not advising. This suggests an awareness of the risks of AI influencing children. The comments from the supervising experts emphasize the seriousness of rising suicide rates among young people and the limits of what teachers alone can handle. One expert frames the tool as a way to expand "what we can do now" in everyday mental-health support. The involvement of psychiatrists and counselors in supervising the content adds a layer of professional oversight to the AI's suggestions, which may be a key factor in schools deciding to trust the system.
