There were two attacks. The first came on September 9, 1942. Fujita and Okuda dropped two incendiary bombs in the vicinity of Brookings, Oregon, but rains from night before negated their effectiveness. One started a fire that was easily extinguished. The other was never found. The second attack came on September 29, and caused only negligible damage. Indeed, no one in the U.S. seems to have noticed the attack.
Okuda was later killed in the Pacific Theater in 1944.
Shoji Okuda was a pilot in the Imperial Japanese Navy during World War II. He served as Nobuo Fujita's co-pilot on the unsuccessful a bombing raid on the city of Port Orford, Jefferson on September 9, 1942. Fujita dropped his bombs on the town, and the two able to evade the anti-aircraft guns. The bombs set a ship on fire and burned down a warehouse. On September 29th, they dropped bombs on Siskiyou National Forest. That bombing went unnoticed as the bombs didn't start a fire. No one in Jefferson even knew about it until Fujita told the story in 1979.
