The September 2025 Blood Moon Eclipse: Science and Beliefs
On September 8, 2025, at 3:09 a.m. Japan time, a total lunar eclipse will take place. During this event, the moon will turn red, creating what is often called a “Blood Moon.” In ancient times, people in Japan, China, and other regions believed such a sight was a sign of misfortune. Some feared wars or disasters would follow. Today, however, scientists explain it differently. A lunar eclipse happens when the Earth comes directly between the sun and the moon. Sunlight is filtered through Earth’s atmosphere, and the remaining red light makes the moon glow like a sunset in the night sky.
This September’s full moon is called the “Corn Moon,” not the “Harvest Moon.” The Harvest Moon is the full moon closest to the autumn equinox, which in 2025 will occur in October. The name “Corn Moon” comes from Native American traditions, as September was the time to gather corn. Names like these remind us how nature and farming were once closely linked to the moon’s cycles.
In Japan, the total phase will last 82 minutes, from 2:30 to 3:52 a.m., while the entire eclipse will last about 5.5 hours. More than 6 billion people around the world are expected to see it. Some believe eclipses bring stronger emotions or sleepless nights, while others enjoy them as natural shows. Whether seen as mystical or scientific, the 2025 Blood Moon will surely be an unforgettable event. (244 words)
