Tadpole rain, Hiroshima prefecture, June 15

Over the past few weeks, people in Japan have been witnessing tadpoles, fish and frogs fall from the sky. Ever since the strange phenomenon was first observed in Ishikawa prefecture on June 4, reports of animal rain have been pouring in from prefectures across the country.

So far, nobody has come up with a plausible explanation for the animal rain. Although some people believe the tadpole showers may be the result of weather disturbances such as waterspouts, no meteorological agencies have observed strong wind or unstable weather conditions in any of the areas where the rain has occurred. Others believe birds may be spitting up large quantities of tadpoles, although many ornithologists dispute this claim. Still others have suggested it may be the work of human pranksters, or even extraterrestrials.

Here is a brief timeline of the occurrences reported so far. This page will be updated as new reports emerge.

Saitama prefecture, late May -- In a loosely related story, an employee at a nursing home in the town of Sakado found a mummified snake on a wooden deck outside the facility one morning. The mummy, which measures about 30 centimeters long and appears to be the dried remains of a baby Japanese striped snake or Japanese rat snake, is coiled up in a strike pose.

It is unclear where the snake came from and how it made its way to the nursing home, although it appears to have fallen from the sky (perhaps it was dropped by a bird). The employee, who believes the unusual find is a sign of good luck, put the snake mummy on display in a glass case in the lobby. However, he was forced to remove it after some residents complained.

June 18, Tottori prefecture -- Early in the morning in the town of Yonago, a 48-year-old resident found 30 tadpole carcasses scattered atop a section of a 5-meter-wide seaside retaining wall. The tadpoles, some of which had begun to develop legs, measured 2 to 4 centimeters long. According to the local weather agency, the maximum wind speed at the time was 3 meters/sec (6.7 mph) and conditions were not favorable for the development of waterspouts. A local biologist claimed it was unlikely that a bird scattered that many tadpoles along the wall.

The witnesses, whose shop is located nowhere near a catfish-populated river, do not believe it is the work of a human prankster. They suspect a bird may have dropped the catfish.

Froglets scattered on rural road, Oita prefecture, July 7

July 7, Oita prefecture -- The bodies of more than 600 tadpoles and froglets were found scattered along a 100-meter stretch of rural road near the town of Kusu. A 69-year-old farmer discovered the carcasses while on the way to check his rice fields in the morning. According to the farmer, who noticed nothing unusual on the road the night before, the irrigation channels and rice paddies near the road contain no water, implying that the froglets may have come from elsewhere.
