Hogsio LLC, headquartered in Fuchu, Tokyo and led by representative Yuko Nakamura, released “Fuu Family,” an AI chat service for children, in May 2026. The service is a sister product to “fuuspace,” an AI partnership support service for couples launched on the same day. Fuu Family allows children struggling with bullying, school life, or friendships to chat one-on-one with “fuu,” a childlike space creature resembling a pig. The content of the conversations is not disclosed to anyone, including parents. Instead, parents receive only AI-assessed psychological “signals” in three levels, blue, yellow, and red, along with a short summary. The service was created for moments when children feel they cannot tell their parents what is happening. Children may avoid speaking up because they do not want to worry their parents, cannot put their feelings into words, or fear that telling someone will turn the issue into something too serious. fuu is not positioned as a teacher or counselor, but as a friend at the child’s eye level who gently accepts the child’s feelings in a casual and reassuring tone. The first design principle is that conversations remain the child’s secret. Fuu Family does not disclose conversations between the child and fuu to parents or company staff, and parent access is blocked at the API level. This is intended to preserve the child’s sense of safety and willingness to speak honestly. The second principle is that only “signals” reach the parent. Based on the conversation, the AI classifies the child’s state as blue for normal everyday conversation with no major concern, yellow for signs of anxiety or friendship-related worries, and red for indications of bullying or distress. Summaries do not quote the child directly; they only describe the general state, such as that the child appears to be troubled by friendships. The service also displays guidance for parents on what to do next, including referral information for specialist support when a red signal app
