The “Spiral UFO” of Tokyo: Robotic Observatory Captures One of Japan’s Strangest Sightings

In the neon-drenched skies above Tokyo, a city that never sleeps, a silent, robotic eye keeps a constant vigil. This automated observatory, known as SID-1, is designed to capture any and all strange phenomena that pass overhead. And on one particular night, it recorded something truly bizarre: a luminous, silvery-white object that moved like no known aircraft or natural event—a “Spiral UFO.”

A Glowing Anomaly in the Night Sky

The footage captured by SID-1 (Space Intrusion Detection System-1), operated by Japan’s Space Phenomena Observatory Center (SPOC), shows an elongated, glowing object streaking across the night sky. Moving at high speed from the upper left to the lower right of the frame, the object emits a brilliant, milky-white or silvery light.

Upon magnification, its form is deeply perplexing. It doesn’t appear to be a solid craft in the traditional sense, but rather something rotating, or perhaps something with a permanent, corkscrew-like spiral shape. It’s an otherworldly and deeply strange sight.

The Analysis: Ruling Out All Conventional Explanations

What could this strange object be? Researchers at SPOC systematically investigated all conventional possibilities, but each one was ruled out.

◆Was it a Meteor or Fireball?
This was the first possibility considered, but it doesn’t fit the evidence. Meteors burn up as they enter Earth’s atmosphere at altitudes of 70-100 km and are visible for only a few seconds. The object captured by SID-1 had a much longer duration of luminescence and appeared to be flying at a significantly lower altitude. Furthermore, its distinct, rotating spiral shape is unlike any meteor ever recorded.

◆A Helicopter or Conventional Aircraft?
This is also highly unlikely. A helicopter does not emit light in this manner, and a check of aircraft tracking services confirmed that no planes were in that specific location at that time.

◆A Flock of Birds, Insects, or a Drone?
The object’s high speed, straight trajectory, and self-luminous nature immediately rule out birds or insects (even luminous ones like fireflies). Its unique shape also does not match any known commercial or military drone.

A Genuine Unidentified Flying Object

After exhausting all logical and natural explanations, the researchers were left with a profound mystery. The object moved with purpose, glowed with its own light, and possessed a shape and motion that do not correspond to any known terrestrial technology or natural event.

The conclusion, therefore, is as clear as the footage itself: the object captured by SID-1 was a genuine Unidentified Flying Object. The “Spiral UFO” of Tokyo remains one of the most compelling and strangest pieces of evidence ever collected by the SPOC observatory, a silent, glowing enigma that serves as a powerful reminder that even above one of the world’s most populous cities, there are still profound mysteries waiting to be seen.
