Korean-resident film director Pak Su Nam said Wednesday that a confession appearing in her latest documentary about mass murder-suicides by civilians in Okinawa in 1945 helped dismiss a lawsuit against writer Kenzaburo Oe.

Oe was recently sued for stating in his book "Okinawa Notes" that Japanese soldiers, facing defeat, issued the orders for the heinous acts.

Pak's documentary, "Nuchi Kafu, Preciousness of Life — Testimonies from the Mass Suicide Caves," features a confession by a key figure, Yukinobu Miyamura, that contradicts a statement used as evidence by Yutaka Umezawa, a plaintiff in the case who was a former garrison commander on Zamami Island.
