Japan launches AI robot monk to offer spiritual guidance

Japan has launched an AI robot monk designed to deliver spiritual advice and assist with religious rituals. The humanoid, called “Buddharoid”, was presented in Tokyo by Kyoto University on February 25, 2026.

Developed by Seiji Kumagai, Institute for the Future of Human Society, the robot uses artificial intelligence models to respond to sensitive questions and provide Buddhist guidance. Researchers say it could help address Japan’s ageing population and shortage of human monks.

The AI robot monk is powered by updated language models, including systems developed by OpenAI. Kumagai installed his upgraded “BuddhaBotPlus” software into a Chinese-made Unitree G1 humanoid robot. The result is a two-legged machine capable of walking, gesturing and offering spoken advice in a calm tone.

The Buddhist robot appeared at a media event which took place at a Kyoto temple while wearing a plain grey robe and held his hands together to pray. The AI robot responded to questions about overthinking by citing Buddhist texts which taught people to practise mindfulness while controlling their emotions.

The AI robot monk at Kyoto University has developed its capabilities to answer spiritual enquiries which people typically avoid discussing with others because it has learned complex Buddhist scriptures.

Buddharoid serves as a religious chatbot because people of different faiths use chatbots for religious purposes, yet it differs from typical chatbots by using both AI technology and physical existence.

Experts believe this combination of robotics and AI technology will transform the way people practise their faith. The university confirmed that ethical issues still exist in this matter. Humanoid AI robots will take over certain priest duties because Japan has a declining workforce, which necessitates their use in upcoming rituals.
