2004: Four Silver Discs Over Tokyo’s Imperial Palace Gardens — A Daylight Sighting
On a bright, sunny afternoon in October 2004, tourists and locals alike stopped and pointed skyward over Tokyo’s Imperial Palace East Gardens as four identical silver discs hung motionless overhead in a tight trapezoid formation — still enough, and public enough, that a passing security patrol stopped, raised binoculars, and radioed it in, before the discs began vanishing from view two at a time until none remained.
Date: October 19, 2004 (witness’s best estimate — possibly the day before or after)
Sighting Time: Approximately 2:00 PM
Day/Night: Daytime — bright and sunny, with high thin stretched clouds
Location: Imperial Palace East Gardens, Tokyo, Japan
Urban or Rural: Urban — corrected from the original field entry of “Rural.” The witness places the sighting in a large open public garden atop a small hill in central Tokyo, one of the most densely urban locations in Japan; “Rural” does not fit this location and appears to be a leftover/default template entry.
No. of Entity(‘s): Undocumented
Entity Type: Not Applicable — no entity described
Entity Description: Not Applicable
Hynek Classification: DD (Daylight Disc) — metallic or whitish object seen in the day. This classification fits cleanly: witnesses directly resolved four flat, round, silver-colored solid discs in daylight.
Duration: Undocumented — witness estimates at least one minute stationary before the objects began disappearing from view; total elapsed time to full disappearance not specified
No. of Object(s): Four
Description of the Object(s): Four circular, flat discs positioned close together, forming the four corners of a trapezoid/tight rectangle shape in the sky. All appeared identical in size and distance from the witnesses; one showed more glare/brightness than the others.
Shape of Object(s): Discs — completely round and flat
Size of Object(s): Undocumented — no size estimate given beyond all four appearing equal to one another
Color of Object(s): Smooth, shiny, silver
Distance to Object(s): Undocumented — witness states the objects were directly overhead and “very high up,” but gives no altitude estimate or measured range
Height & Speed: Undocumented altitude. Objects appeared stationary for at least a minute, then seemed to float/drift slowly together while mostly holding formation, before vanishing from view two at a time.
Number of Witnesses: Many — the reporting witness and two named companions (ages 65 and 31, the latter carrying a 2-year-old), plus numerous unnamed tourists and locals, and two security guards who stopped to observe with binoculars and radio
Special Features/Characteristics: No aircraft were reported in the area at the time. No sound was reported. The four discs disappeared from view in pairs rather than all at once, with the brightest disc remaining visible longest. A security patrol car stopped, and one guard used binoculars while the other communicated by radio. The witness also recalls tremors during the same week, with a major earthquake occurring approximately a week after leaving Japan — see Researcher’s Notes for verification of this detail.
Case Status: Insufficient Data — a multi-witness, publicly visible sighting with an official (security) response present, but no independent news account, photograph, or corroborating record has been located, despite the original witness’s own attempts to find press coverage
Source: Reported to Think AboutIt
Summary/Description: Hello, I was in Tokyo a couple weeks ago and in the middle of the day saw these four discs that countless other people saw. I am back home in NYC now and trying to Google info or articles about the possible sighting but I am not very good at searching or can’t find the newspapers or sites. Can you please lead me to some websites that might have reported this incident so I can read more about it. I think the date was Oct. 19 or the day before or after. Thanks.
Additional Information, provided by the witness in response to follow-up questions:
Weather conditions: Very bright and sunny, with thin, long, stretched-out high clouds rather than puffy ones. A typhoon was approaching within a day or so, though the sky was very bright at the time.
Position in sky: Directly overhead.
Movement: The witness and two friends noticed other people already looking up. The objects did not appear to move for about a minute, remaining very still high in the sky, then seemed to float together while mostly retaining their formation. Two of the four then seemed to vanish; the witness had to look hard to relocate a second one, and the remaining two eventually vanished as well while still overhead, moving in a direction the witness could not determine. Many bystanders stopped, stared, and pointed. A security car with two guards stopped to observe; one used binoculars while the other communicated by radio.
Appearance: Four circular discs positioned close together, forming the four corners of a trapezoid or tight rectangular shape, all appearing the same size and distance from the witnesses. All were flat, round discs, identical in shape and size, smooth, shiny, and silver-colored; one showed more glare than the others and appeared to be oriented in the direction the group was moving. The witness reports the brightest disc was the only one visible for the entire sighting.
Location detail: A large open space atop a small hill in the middle of Tokyo, within the public gardens of the Imperial Palace, near where tourists and locals gather on the grass. Two airports are known to the witness in the general area, one to the east/north and one farther south.
Aircraft present: None reported.
Additional context: The witnesses were leaving the gardens around 2:00 PM when they noticed local older residents (in their 60s-70s) pointing at the sky, which drew the attention of both locals and tourists nearby. The witness was accompanied by two friends, one 65 years old and one 31 years old carrying a 2-year-old child; all reported seeing the discs. The witness also recalls experiencing earthquake tremors in the middle of the night during the same week, with a larger earthquake occurring about a week after the witness left Japan.

Detailed Report
The witness’s account was reconstructed after the fact, at the witness’s own request, through a structured question-and-answer exchange with Think AboutIt rather than an initial detailed narrative — the original submission was simply a request for help locating press coverage of an event the witness assumed, reasonably, had been widely reported given the number of people present. It was not. According to the reconstructed account, the witness and two companions were leaving the public gardens of Tokyo’s Imperial Palace, an elevated open space in the heart of the city, around 2:00 PM on a bright, sunny day, when they noticed a crowd of locals and tourists already stopped and pointing skyward. Directly overhead, four flat, round, silver-colored discs held a tight trapezoid formation, motionless for at least a minute before appearing to drift together while largely retaining that shape. The sighting drew a substantial public reaction, including a security patrol car whose occupants stopped to observe, one using binoculars, the other communicating by radio — an institutional response that corroborates the event’s public visibility, even without confirming its nature. The objects then began to vanish from view two at a time, the brightest of the four remaining visible longest, until all four were gone. No aircraft were present, no sound accompanied the event, and no photograph was taken. The witness’s own later effort to locate news coverage from New York, after returning home, was unsuccessful — a gap this report cannot resolve either, despite the sighting’s apparent public scale.
RESEARCHER’S NOTES
The Imperial Garden Discs — Tokyo 2004 and the Gap Between Public Sighting and Public Record
- Classification Assessment: DD (Daylight Disc) is a clean fit for this case, unlike many “disc” reports that turn out to be lights-only. Witnesses directly resolved four flat, round, metallic-silver objects in full daylight at close enough visual range to note a difference in glare between one disc and the others — a level of surface detail that supports the classification rather than merely presuming it.
- Source Chain Assessment: The account was built through a Q&A exchange initiated by the witness, who was seeking outside corroboration rather than offering an unprompted narrative — a structure that suggests genuine surprise and a search for validation rather than an elaborated tale. However, the report remains a single first-person source; the “countless other people” and named companions who reportedly witnessed the event are described secondhand by the primary witness, not independently interviewed.
- Evidentiary Weight: No photograph, video, or press account accompanies this report, and the witness’s own attempt to locate coverage after the fact came up empty. The presence of a security patrol that stopped and responded with binoculars and radio communication is a meaningful, semi-official corroborating detail — it confirms something drew public and institutional attention that day — but it does not by itself confirm the nature of what was seen.
- Pattern and Comparative Context: Multiple identical discs holding tight formation before disappearing from view individually or in pairs is a recurring report structure in daylight disc testimony, and the “vanishing” description here is also consistent with mundane explanations — bright, reflective objects at high altitude and extreme distance can become effectively invisible against a bright sky the moment sunlight glare shifts off their surface, without requiring literal teleportation or cloaking.
- Geographic and Historical Context: The Imperial Palace East Gardens sit in central Tokyo, a heavily monitored urban environment with two airports in the general region as the witness notes, making conventional aircraft, balloons, or reflective debris plausible candidates worth weighing against the report. The witness’s recollection of minor tremors that week followed by a larger earthquake about a week after leaving Japan lines up with the historical record: a major M6.6-6.8 earthquake sequence struck Niigata Prefecture on October 23, 2004 — the deadliest to hit Japan since the 1995 Kobe quake. This confirms the witness’s general timeline was accurate, though Niigata is a separate region from Tokyo and the earthquake itself has no established connection to the sighting.
This case is unusual less for what was seen than for what wasn’t found afterward: a sighting substantial enough to draw a crowd and a security patrol response, in the middle of one of the world’s most photographed cities, yet apparently undocumented anywhere outside this single witness’s memory. Absent a photograph, a press account, or a second independent witness statement, the record stands as Insufficient Data — a public event with no public trail.
“They were four circular discs, they were very close to each other and made up the four points/corners of what I would consider a trapezoid shape in the sky.”
