Some 1,000 people today gathered at a former airbase of the kamikaze squad in southwestern Japan, to mourn the loss of the lives of suicide mission pilots seven decades ago. The memorial service was held in Chiran, southern Kyushu, from which 439 kamikaze pilots left for suicide missions ― known as “Tokko” in Japan ― and did not survive, towards the end of World War II, public broadcaster NHK said.
