Norihisa Hosokawa | Founder and AI Tailor


"True luxury isn't about having more technology, but about having technology that you know when to stop using. As an engineer and a father, I meticulously create AI to protect those quiet, irreplaceable moments spent in the living room. My policy is that the greatest happiness comes from seeing my family laughing heartily in the living room."

SAFETY, PRIVACY & RESPONSIBLE AI NOTICE

HAKONE AI is designed as a family-focused digital wellbeing and parent-child communication support service.

It is not a medical, therapeutic, diagnostic, or emergency service. HAKONE AI does not diagnose, treat, prevent, or predict any disease, disorder, mental health condition, or school attendance outcome.

Our purpose is to support calmer screen-time routines, parent-child dialogue, and household rules around digital devices.

We design HAKONE AI with reference to widely discussed principles in child safety, privacy, responsible AI, data minimization, transparency, and human oversight. These include international discussions around children’s rights, AI governance, and privacy protection.

HAKONE AI is intended to be used with parental involvement. Use by children or minors should take place with the consent and supervision of a parent or legal guardian.

We aim to collect only the information necessary to provide the service and to explain how personal information is handled in our Privacy Policy. Data handling, storage, third-party AI providers, and security practices are described in our Privacy Policy and Terms of Service.

HAKONE AI is an independently developed service operated by Synapse Cascade Gomei Kaisha. It may use third-party AI infrastructure or APIs to provide certain features, but it is not affiliated with, endorsed by, or officially partnered with any AI provider unless expressly stated.

For urgent safety, medical, psychological, or emergency concerns, please contact appropriate local professionals or emergency services.
