TOKYO — In a poignant discovery that has reignited a long-standing historical grievance, Japanese police have confirmed that bones found deep within the flooded Chosei underwater coal mine are indeed human remains. This breakthrough provides a grim, tangible link to the 1942 tragedy that claimed the lives of 136 Korean and 47 Japanese forced laborers.

The identification of the bones, which include a femur and a skull, has amplified calls for the Japanese and South Korean governments to take official responsibility for the recovery and repatriation of the victims. For over 80 years, the bodies of those who perished in the catastrophic mine flood have remained entombed within the submerged shafts off the coast of Ube City, Yamaguchi Prefecture.

The bones were discovered by a Korean diver working with a Japanese civic group, "The Society to Inscribe the Chosei Coal Mine Drowning Accident in History." The group, which has been conducting underwater searches since last year, submitted the remains to the local Yamaguchi Prefectural Police for forensic analysis. This finding represents the most significant progress to date in efforts to bring the victims home.

"After 83 years, the remains of victims who waited in the seabed have been brought out of the water through the efforts of citizens from both countries," stated the "Jangsaeng (Chosei) Coal Mine Victims' Repatriation Promotion Team," a Korean civic group. Their statement emphasized that the subsequent tasks of DNA identification, locating families, and repatriating the remains are now beyond the capacity of private organizations. They issued a strong appeal for official government involvement, proposing the establishment of a "Korea-Japan Remains Consultation Body" to facilitate the process.

The 1942 disaster occurred when a sudden water leak caused the mine to flood, trapping and drowning 183 workers. The majority of the victims were Korean laborers who had been conscripted to work under harsh conditions during Japan's colonial rule.

Historically, the Japanese government has maintained a stance of non-intervention, citing the difficulty of pinpointing the location of the remains and a lack of safety assurances for an underwater recovery mission. This position has been a point of friction, with civic groups on both sides of the Strait arguing that official neglect has prevented a proper accounting for the victims.

The recent discovery now places renewed pressure on Tokyo to re-evaluate its position. With a powerful symbol of the tragedy now confirmed, advocates believe the moral imperative for official action is undeniable. The discovery serves as a powerful reminder of the thousands of Korean forced laborers who died in Japan's mines and factories, and whose stories remain largely untold and their remains unrecovered.

"It's time for the governments to step up," said one representative from the Japanese civic group, whose members have long pushed for an official inquiry and recovery mission. "This is no longer a matter of history, but a humanitarian mission."
