In Japan, the storage of ultra-pure water underground serves the purpose of neutrino research – a tiny particle that plays a crucial role in our understanding of the universe.
Ultra-Pure Water: Unfit for Humans, but Invaluable for Science
The concept of “ultra-pure water” may sound like a premium version of regular drinking water, but in reality, it is not only undrinkable but can also be dangerous if consumed excessively. This type of industrial water is refined to the point where it contains almost no impurities, including dissolved solids. In Japan, 50,000 tons of ultra-pure water are stored underground, not for domestic use but for a special mission: neutrino detection.

Japan stores 50,000 tons of ultra-pure water at a depth of 1,000 meters to support scientific research, particularly in the field of particle physics. One of the main applications of this ultra-pure water is in neutrino detectors, such as the Super-Kamiokande detector.
Neutrinos: Tiny Particles Holding the Universe’s Great Secrets
Neutrinos are among the fundamental particles of the universe, having no electric charge, an extremely small mass, and an extraordinary ability to penetrate matter. Due to these characteristics, neutrinos are often referred to as “ghost particles” – elusive and almost non-interacting with normal matter. Although the existence of neutrinos was predicted in the late 19th century, it wasn’t until the mid-20th century that scientists were able to confirm their existence.
Researching neutrinos not only opens new doors in particle physics but also provides crucial information about geophysics, astrophysics, and even the origins of the universe. This is why neutrinos have become a highly sought-after subject in the global scientific community.

Ultra-pure water is used to detect neutrinos, which are very difficult to observe because they interact very little with matter. The Super-Kamiokande detector, situated 1,000 meters underground, contains 50,000 tons of ultra-pure water to create an ideal environment for detecting and studying these particles.
Super-Kamiokande: Japan’s “Eye” for Neutrino Hunting
To capture neutrinos, Japan has constructed the “Super-Kamiokande Detector” – a massive facility located deep underground. This device consists of a gigantic cylindrical tank filled with ultra-pure water equipped with thousands of highly sensitive photomultiplier tubes.
When neutrinos collide with the nuclei of water molecules, they produce faint flashes of light. The photomultiplier tubes record this phenomenon, allowing scientists to analyze its spectrum. This is the key to unlocking the mysteries of neutrino properties, thereby addressing many unanswered questions about the formation and operation of the universe.

Additionally, storing ultra-pure water at great depths also protects it from external environmental factors, ensuring the purity and stability of the water during research.
Challenges in the Exploration Journey
Despite achieving significant milestones, scientists still face many challenges in neutrino research. These particles are so small and difficult to detect that they require even more advanced equipment and techniques. Japan’s plan to store ultra-pure water is expected to create breakthroughs, not only in scientific research but also in enhancing the country’s international standing in technology.
Not only Japan, but China is also actively participating in the race to research neutrinos. Although China’s scale of ultra-pure water storage is smaller, international collaboration has opened opportunities for scientists worldwide to shed light on the mysteries of neutrinos.

Connecting Science and Everyday Life
Beyond the controversies surrounding nuclear waste disposal, Japan is demonstrating that investing in fundamental science, such as neutrino research, not only contributes to humanity’s knowledge base but also holds the potential for unexpected applications in everyday life.
Through international collaboration and efforts to innovate technology, the journey to decode neutrinos is gradually bringing us closer to helping humanity understand the principles governing the universe. And who knows, one day, the mysteries of this tiny particle may lead to great breakthroughs, changing the way we perceive the world.
Ultra-pure water, also known as ultra-pure water, is a type of water that has been treated to remove almost all impurities, including dissolved solids and bacteria. This makes ultra-pure water one of the purest forms of water, free from any contaminants that could affect scientific experiments.
Ultra-pure water is commonly used in fields such as scientific research, semiconductor manufacturing, and healthcare. For example, in neutrino detectors like Super-Kamiokande in Japan, ultra-pure water is used to detect neutrinos, which are fundamental particles that are very difficult to observe due to their minimal interaction with matter.
However, ultra-pure water is not suitable for drinking as it lacks essential minerals required for the body and can be hazardous if consumed excessively.
