In the summer of 1939, a fierce aerial battle unfolded over Tomsk, near the border of Manchuria and Mongolia. This was during the Soviet-Japanese border conflict, a time when tensions were high, and the skies were filled with over 150 airplanes engaged in combat. Among the pilots was Warrant Officer Hiromichi Shinohara of the Imperial Japanese Army Air Force. This was a period just before World War II officially began, and Japan had not yet attacked the U.S. Pacific Fleet at Pearl Harbor.
The conflict, known as the Battles of Kalkangol or the Namanhan Incident, is not widely remembered today. However, at the time, it was a significant and bloody confrontation. These battles lasted from May to September 1939, resulting in over 45,000 casualties and the destruction of around 360 aircraft. The scale of air combat was immense, reminiscent of the intense aerial battles of World War I.
During this four-month clash, both Japan and the Soviet Union flew over 12,000 sorties, fired nearly 3 million rounds of ammunition, and dropped over 2,000 tons of bombs. The conflict ended in a defeat for Japan, rooted in tensions that began in 1931 when Japan invaded Manchuria. Disputes over the Manchurian-Mongolian border continued to simmer, occasionally erupting into open warfare.
On May 11, 1939, a small incident involving Mongolian cavalry crossing the border for grazing land escalated into a full-scale conflict. Both sides deployed numerous planes and tanks, including the Soviet Tupolev TB-3 heavy bomber and the Japanese Mitsubishi K-21 Sally high-speed bomber. By the end of June, Japan launched a major assault, hoping to quickly end the conflict, but the attack failed despite heavy air support.
On June 27, a massive air battle took place over Tomsk. Shinohara, a career pilot who had transferred from the cavalry in 1932, was flying combat missions for the first time with the 11th Squadron. He piloted the Nakajima Ki-27 Nate, a modern Japanese monoplane. Despite its light armament, Shinohara shot down four Soviet Polikarpov I-16 fighters on his first mission, showcasing his exceptional skills.
Shinohara’s dogfighting style was unique, resembling a lone wolf hunting its prey. He preferred to fly solo, patiently waiting for the perfect moment to strike. The day after his first mission, he downed six more enemy planes using swift, high-speed attacks. His reputation as a flying ace was quickly established.
On June 27, Shinohara achieved an extraordinary feat by shooting down 11 enemy aircraft in a single day. This accomplishment placed him among the elite pilots of the era. In July, he demonstrated bravery by landing on the battlefield to rescue a fellow pilot, although his aircraft was damaged in the process.
By August 27, 1939, Shinohara had achieved 55 aerial victories. Tragically, during a mission over Mohore Lake, he was attacked by a large group of I-16 fighters. Despite being outnumbered, he managed to shoot down three attackers before his plane was hit and crashed into the lake, resulting in his death. He was only 26 years old.
Shinohara was posthumously promoted to Flight Officer (Second Lieutenant). His record of 58 Soviet aircraft shot down in less than 93 days remains unmatched by any other Japanese Army pilot. Although some Japanese naval pilots during World War II surpassed this number, Shinohara’s legacy as a remarkable fighter ace endures.
Sadly, many Japanese pilots who survived the border conflict did not live through the intense battles of World War II, particularly the destruction of the Japanese Air Force in 1945.

Hiromichi Shinohara: The Deadly Warrior of the Skies, 1939.
On June 27, 1939, over Tomsk, on the border of Manchuria and Mongolia, during the Soviet-Japanese border conflict, a massive aerial dogfight took place involving over 150 airplanes. One of the pilots in the thick of this fighting was Warrant Officer Hiromichi Shinohara of the Imperial Japanese Army Air Force. This was just before World War II began, nearly two and a half years before Japan entered the war after the attack on the U.S. Pacific Fleet on December 7, 1941.
The battles of Kalkangol, also known as the Namanhan Incident, are today largely forgotten, but at the time, these Soviet-Japanese border conflicts were both bloody and costly. They lasted from May to September 1939, with over 45,000 casualties and around 360 aircraft destroyed. The air combat was on a scale and ferocity not seen since the aerial bloodbath known as Bloody April in 1917 on the Western Front during World War I.
During the four-month-long border clash between Japan and the Soviet Union, it’s estimated that both sides combined flew over 12,000 sorties, with nearly 3 million rounds of ammunition fired and over 2,000 tons of bombs dropped. The conflict ended in a humiliating defeat for Japan and had its roots back in 1931 when Japan invaded Manchuria in Northwest China. Relations with Soviet-backed Communist Mongolia quickly became strained and erupted briefly into open warfare in 1938, resulting in the Battle of Lake Kasan during the short-lived Chankufeng Incident. Although a diplomatic solution was quickly found and hostilities ceased, disputes over the Manchurian-Mongolian border persisted.
On May 11, 1939, a detachment of Mongolian cavalry crossed the border to find grazing land for their horses. This prompted the Manchurians to send a large cavalry detachment to chase off the intruders. However, tensions escalated over the following weeks, and what began as a minor border dispute turned into a full-scale conflict involving numerous planes and tanks, including the obsolete Soviet Tupolev TB-3 heavy bomber and the latest Japanese Mitsubishi K-21 Sally high-speed bomber.
Towards the end of June, the Japanese launched a full-scale assault on Soviet and Mongolian positions in an attempt to bring the conflict to a quick conclusion. This attack ultimately failed, despite heavy support from their bomber and fighter aircraft. It was the first time air power had been used on such a large scale to support an advancing army, resulting in some of the largest air battles since World War I.
The giant air battle over Tomsk on June 27 was a pivotal moment in the Japanese offensive. Warrant Officer Shinohara had just started flying combat sorties for the first time with the 11th Squadron of the Japanese Imperial Army Air Force. They had recently been redeployed to a newly built airfield at Syenzo, located in western Manchuria, east of the border with Mongolia. The base was crucial as it was the nearest Japanese airfield to the front lines.
Shinohara, a career pilot and the son of a peasant farmer, had risen through the ranks of the Army Air Force after transferring from the cavalry in 1932 at the age of 19. Although he had been flying fighter aircraft from the start of his career, it wasn’t until 1939 that he saw his first combat mission. By the time the Soviet-Japanese border conflict began, he was flying the modern Japanese monoplane, the Nakajima Ki-27 Nate, which was the forerunner of the legendary Mitsubishi Zero. The Nate was a capable fighter aircraft, albeit lightly armed with just a pair of medium machine guns. Despite this, Shinohara managed to shoot down four of the latest Soviet Polikarpov I-16 fighters on his very first combat mission, an incredible accomplishment given the I-16’s formidable capabilities.
Shinohara’s dogfighting technique quickly became apparent and was likened to that of a lone wolf hunting its prey. He preferred flying alone, patiently stalking his targets from above until he found the right moment to strike. The following day, he added six more enemy aircraft to his tally using the classic Japanese tactic of swooping down at high speeds and turning sharply to fire.
There was a rumor that during one engagement, as an I-15 pilot parachuted from his damaged aircraft, Shinohara’s wingtip clipped the man’s chute, causing it to tear. It’s unclear if this was deliberate or accidental, but Shinohara’s record remained spotless. He became a flying ace in just the first two days of combat.
He continued to score aerial victories over the Soviets in the following weeks. On June 27, he shot down 11 enemy aircraft in a single day, a feat only surpassed by a handful of other pilots during World War II. In July, he displayed great courage by landing his aircraft on the battlefield to rescue a downed fellow pilot, although his aircraft was damaged in the process, requiring both pilots to be rescued under fire.
By August 27, 1939, Shinohara had amassed an impressive 55 victories. While escorting a bomber formation over Mohore Lake, he was attacked by a large group of I-16 fighters. Despite being outnumbered, he managed to shoot down three attackers before his plane was hit, sending it spiraling downwards in flames and resulting in his death as it crashed into the lake. He had just celebrated his 26th birthday a few weeks prior.
Recovered from the wreckage were his watch, identity tag, a can opener, and a German Mauser Model 1914 automatic pistol he had taken from a Soviet prisoner of war. Shinohara was posthumously promoted to the rank of Flight Officer (Second Lieutenant). Before his death, he had shot down a total of 58 Soviet aircraft in less than 93 days, a record that was never surpassed by any other Japanese Army pilot, although some Japanese naval pilots during World War II went on to shoot down more planes.
Sadly, very few Japanese pilots who survived the border conflict lived through the intense fighting of World War II, particularly the destruction of the Japanese Air Force in 1945.
