Workers have unearthed the remains of more than 1,500 people in western Japan. Archeologists report finding evidence that many of those individuals died of disease, possibly in an epidemic. The burial ground is thought to date back to the 1850s. It is being dug up for a development project in the city of Osaka. Officials at Osaka’s City Cultural Properties Association have studied the remains. They said many of the individuals were likely in their 30s or small children when they died. The Umeda Grave is one of seven historical burial grounds in Osaka. It was discovered near a main train station as part of a redevelopment project that began in September 2019.
