Japan's Secret War

This groundbreaking investigation reveals how a secret atomic weapons program in WWII Japan led to today’s North Korean security crisis.

Japan’s Secret War explores one of the least-known, yet highly significant episodes of World War II: Japan’s frantic race to develop its own atomic bomb. Journalist and historian Robert Wilcox then shows how Japan’s efforts evolved into North Korea’s nuclear program and the looming threat it presents to mankind.

After decades of research into national intelligence archives in the US and abroad, Wilcox presents a detailed account of Japan’s version of the Manhattan Project. He traces its development from inception to the possible detonation of a nuclear device in 1945.

Wilcox weaves a fascinating portrait of the secret industrial complex where Japan’s atomic research culminated. And it is there that North Korea, following the Japanese defeat, salvaged what remained and fashioned its own nuclear program.

“Japan’s Secret War is still spellbinding. It is intriguing and disturbing, and Robert Wilcoxdeserves high praise for his meticulous research.” —Historynet.com
