Discovery of 12,000-Year-Old Underwater Pyramid in Japan Sparks Debate on Ancient Civilizations

A massive sinkhole measuring approximately 40 meters in diameter emerged early Tuesday in Yashio, Saitama Prefecture, Japan, swallowing a 74-year-old truck driver. Authorities have reported that the hole's expansion is likely due to corroded sewage pipes, creating what local officials described as "an extremely dangerous condition." Emergency workers began rescue operations and are constructing a 30-meter slope from a safer area to reach the trapped driver, who has not been heard from since the incident occurred.
According to local fire chief Tetsuji Sato, the situation is complicated by ongoing erosion of the hole's walls, which has made it unsafe for rescuers to remain close for long periods. The cavity has deepened to about 10 meters, and officials noted that heavy chunks of asphalt occasionally fall into the site, hindering rescue efforts. Approximately 1.2 million residents in the surrounding area have been urged to conserve water to prevent sewage leaks from exacerbating the situation.
Rescue operations are ongoing, with hopes to complete infrastructure work by Friday, although severe conditions may delay the effort.
