An exhibition hall in Tokyo's Chiyoda Ward dedicated to victims of the wars fought by Japan in the 1930s and 1940s will not challenge visitors to think too deeply about how Japan waged those wars and its responsibility for them.

This is not an oversight. The new national peace memorial hall named Showa Kan (Showa Hall) that houses the display was designed that way.

The controversial hall finally opens today, four years behind schedule due to protests, debate and confusion.
