A military factory that was said to be the largest in the Orient was once in operation at a site now part of Osaka Castle Park at the center of the city of Osaka, and a researcher is calling for the remaining buildings to be preserved as a "negative legacy."

Osaka Army Arsenal, which manufactured artillery for the now-defunct Imperial Japanese Army, employed up to around 66,000 people, including mobilized students, across its approximately 6-million-square-meter site.

It is very easy to be critical of Japan when talking about smoothing over one's own history. Hopefully, those in charge do preserve a monument to the senseless destruction of humanity as an example to the future about the values of today.
