Japan has unveiled what researchers describe as its first AI Buddhist monk robot, a humanoid machine designed to support Buddhist clergy as the country faces a shrinking population and a growing shortage of temple priests.
Kyoto University researchers presented the robot, known as Buddharoid, at Shoren-in temple in Kyoto. The project aims to preserve religious practice as many temples struggle to remain active, particularly in rural areas where aging priests lack successors.
Buddharoid uses an artificial intelligence system called BuddhaBot-Plus, which is based on OpenAI’s ChatGPT. Researchers trained the system on a wide range of Buddhist scriptures, including specialized religious texts. The robot can answer questions on personal concerns and social issues by drawing from Buddhist teachings.
During the demonstration, Buddharoid moved slowly through the temple, bowed and placed its palms together in prayer. It also responded to questions from visitors and researchers. When asked about human relationships, the robot advised that improvement comes from self-reflection and maintaining inner balance, according to the research team.
AI Buddhist monk robot designed to support declining temples
The project is led by Seiji Kumagai at Kyoto University’s Institute for the Future of Human Society. Kumagai, who is also a Buddhist monk, explained that the robot could help monks or act in their place during some services as the number of temples continues to decline. He said the technology could mark a major shift in how religious duties are supported.

The robot’s physical design is based on a commercially produced humanoid model made by China’s Unitree Robotics. Engineers adapted the hardware to reproduce movements commonly seen in Buddhist rituals, including a slow walking style, bowing, and the gassho gesture used in prayer.
Researchers said Buddharoid differs from earlier religious robots, which were largely limited to scripted speeches. This system allows for real-time conversations combined with physical presence inside temple spaces.
Technology meets tradition in Japan’s religious landscape
Japan’s religious sector has been affected by depopulation and lower religious participation. Experts estimate that about 30 percent of Buddhist temples could disappear by 2040. Aging clergy and declining attendance have made it difficult for many temples to survive.
Buddharoid builds on earlier efforts to blend technology and religion in Japan. In 2019, Kyoto’s Kodai-ji temple introduced Mindar, a humanoid robot that delivered pre-recorded sermons. Researchers say the new AI Buddhist monk robot goes further by offering interactive dialogue and a stronger sense of presence.
Developers stressed that the robot is meant to assist monks, not replace them, as Japan searches for ways to maintain its religious traditions.
