Osaka, Japan, is drawing keen attention as a large group of mullet has been spotted on the Dotonbori River. Some speculate that it may be a “alteration phenomenon” of a major earthquake.

Recently, according to foreign media such as Yomiuri TV, fish were seen swimming in groups enough to fill the surface of the Dotonbori River in Osaka on the 18th.

At that time, tourists and citizens passing by the riverside stopped at the sudden sight.

The video is rapidly spreading through social network services (SNS) such as X (formerly Twitter).

In the video, fish are seen so densely packed that the river is hardly visible. Dotonbori is a busy street in central Osaka and is well known to Korean tourists.

Netizens who saw this expressed concern that the appearance of a mysterious group of fish could be “a precursor to a major earthquake.” One netizen said, “Even during the Great Hanshin Earthquake in 1995, there was a case where a group of fish appeared in the river.”

In addition, the Japan Meteorological Administration issued a “future earthquake warning information” around Aomori Prefecture amid heightened alertness to a major earthquake after a 7.5-magnitude earthquake struck off the coast of Aomori Prefecture in Honshu on the 8th.

In this regard, experts explained, “We need to be careful in directly linking the fish herd to the earthquake,” adding, “The fish found in the Dotonbori River are likely mullets that have moved to find food following the tide.”
