Tsuruhiko Kiuchi

Astronomy and Comet Discovery

Tsuruhiko Kiuchi (1954–2024) was a Japanese astronomer and comet hunter from Nagano Prefecture who made significant contributions to both conventional astronomy and UFO research. After studying at Tokyo University, Kiuchi joined the Tokyo Astronomical Observatory (now the National Astronomical Observatory of Japan) as a researcher. As a comet hunter, he discovered Comet Cernis-Kiuchi-Nakamura on March 16, 1990, and Comet Tsuchiya-Kiuchi on July 16, 1990. His interest in astronomy began in childhood when he observed Comet Iketani-Seki (C/1965 S1), an event that sparked a lifelong fascination with celestial phenomena.

UFO Research and the Kiuchi Method

In 1958, while observing through a telescope, Kiuchi spotted an object that moved with erratic, inexplicable speed and maneuverability—an encounter that redirected his scientific focus toward unidentified aerial phenomena. Recognizing the need for systematic, rigorous investigation in a field often dismissed as pseudoscience, Kiuchi established the Japan Flying Saucer Research Association (JFSRA) in 1961. He developed strict protocols for investigating UFO sightings and emphasized scientific methodology at a time when UFO research lacked institutional credibility.

Kiuchi's most significant contribution to UFO research was the "Kiuchi Method," a mathematical model based on celestial mechanics principles for calculating UFO trajectories. This approach gained international recognition among researchers, offering quantifiable analysis of UFO flight paths and speeds—bridging the gap between anecdotal sighting reports and rigorous scientific calculation.

Near-Death Experience and Consciousness Research

In the early 1980s, while serving as a flight dispatcher for the Japan Air Self-Defense Force at Hyakuri Air Base, Kiuchi developed a rare medical condition (mesenteric artery duodenal obstruction) that resulted in clinical death. Miraculously revived 30 minutes after vital signs ceased, Kiuchi experienced multiple near-death experiences (NDEs) that profoundly altered his research trajectory. These experiences led him to investigate consciousness, paranormal phenomena, and claims of time travel—areas he explored through subsequent books that became bestsellers in Japan. His later work connected UFO research with broader questions about consciousness and non-ordinary states of awareness.

Legacy

Kiuchi's career exemplified a rare synthesis of rigorous scientific methodology with openness to paranormal and consciousness-related phenomena. He demonstrated that serious UFO research could exist within mainstream scientific frameworks while acknowledging the profound mysteries surrounding consciousness and the nature of reality. He passed away in December 2024 at age 70.
