Introduction
Neutrinos, one of the elementary particles, are the second most numerous subatomic particles in the universe after light, and are produced by the universe, the sun, the earth, and even your own body, flying through space. They hardly interact with matter, and their properties are not well understood in comparison to other subatomic particles. Among them, the investigation of the nature of Majorana is the key to understanding that the universe is made of matter, not antimatter. On the other hand, the ability of neutrinos to slip through anything can be used as a means of observing things that were previously invisible. To capture a large number of neutrinos requires a large detector. We are exploring the mysteries of neutrinos with a large detector called KamLAND, which uses 1,000 tons of liquid scintillator. About 60 researchers from Japan, the U.S., and the Netherlands are participating in this international collaboration. Large-scale experiments is from the accumulation of small experiments and research and development. To search for new seeds of experiments, we are also developing small detectors and constructing a low background environment.

Self introduction
My field of focus is elementary particle physics, especially neutrino experiments. Our detector, KamLAND is located at Kamioka and I sometimes stay there to proceed our research. There's still a lot I don't know about this Tokachi area, so I'm excited to explore and discover new places.
