Mitsumasa Yonai

Mitsumasa Yonai (米内 光政) was an admiral in the Imperial Japanese Navy, and politician. He was the 37th Prime Minister of Japan from 16 January to 22 July 1940.

Early life and naval career
Yonai was born in Morioka city, Iwate Prefecture as the first son of an ex-samurai retainer of the Nambu clan of the Morioka Domain. He graduated from the 29th class Imperial Japanese Naval Academy in 1901, ranked 68 of 125 cadets (Japan Center for Asian Historical Records, n.d.). After midshipman service on the corvette JAPANESE IRONCLAD Kongō, and cruiser JAPANESE CRUISER Tokiwa he was commissioned as ensign in January 1903. He served in administrative positions until near the end of the Russo-Japanese War of 1904-1905, when he went to sea again on the destroyer JAPANESE DESTROYER Inazuma and the cruiser JAPANESE CRUISER Iwate.

After the war, he served as chief gunnery officer on the cruiser JAPANESE CRUISER Niitaka, battleship JAPANESE BATTLESHIP Shikishima, and cruiser JAPANESE CRUISER Tone.

After his promotion to lieutenant commander in December 1912, he graduated from the Naval War College and was assigned as naval attaché to Russia during the height of World War I, from 1915-1917.

While overseas, he was promoted to commander; after the collapse of the Russian Empire, he was recalled to Japan and later became executive officer on the battleship JAPANESE BATTLESHIP Asahi.

He rose to the rank of captain in December 1920 and was subsequently sent as naval attaché to Poland from 1921-1922.



On his return to Japan, he was captain of the cruisers JAPANESE CRUISER Kasuga (from 1922–1923) and Iwate (1923–1924), and battleships JAPANESE BATTLESHIP Fusō (in 1924) and JAPANESE BATTLESHIP Mutsu (from 1924–1925). Yonai was promoted to rear admiral on December 1, 1925.

He became Chief of the 3rd Section of the Imperial Japanese Navy General Staff in December 1926. Within the Navy General Staff, he served on the Technical Council of the Navy Technical Department.

He was appointed Commander-in-Chief of the First Expeditionary Fleet, sent to the Yangtze River in China in December 1928. Following the success of this mission, he was promoted to vice-admiral in December 1930 and placed in command of the Chinkai Guard District, in Korea.



Yonai was given command of the IJN 3rd Fleet in December 1932, following which he again commanded the Sasebo Naval District (November 1933), IJN 2nd Fleet (November 1934) and Yokosuka Naval District (December 1935) before receiving appointment as Commander-in-Chief of the Combined Fleet and concurrently the IJN 1st Fleet in December 1936.

While in command at Sasebo, the Japanese Navy was shaken by the "Tomozuru Incident", when it was determined that the basic design of the s was flawed, thus calling into question the basic designs of many of the warships in the Japanese navy.

While in command at Yokosuka, the February 26 Incident erupted in Tokyo. Yonai was visiting his mistress in Shimbashi the night the attempted coup d'état began, only a couple of blocks away, but knew nothing of the situation until he returned to base the following morning.

Naval Minister
Yonai became full admiral in April 1937 and Navy Minister in the cabinet of Prime Minister Senjūrō Hayashi in 1937. He served in the same position under the subsequent first Fumimaro Konoe and Kiichirō Hiranuma administrations, through August 1939.

After Nobuyuki Abe became Prime Minister, Yonai remained on the Supreme War Council. While Navy Minister, Yonai was known as a man of few words. His speeches tended to be short, and were delivered in his almost indecipherable Nambu accent. Written records of his speeches are only about half the length of his contemporaries.

As Navy Minister, Yonai was alarmed by the growing tension between Japan and Great Britain and the United States, at a time when the bulk of the Imperial Japanese Army was tied down in an apparently unending quagmire in China. His efforts to promote peace made him unpopular with ultranationalist extremists, and (as with Admiral Isoroku Yamamoto), he was the target of several assassination attempts. However, Yonai supported the construction of the s in an effort to maintain a military balance with the world's other two naval superpowers.

Prime Minister of Japan


Yonai was appointed Prime Minister of Japan from 6 January 1940, largely with the backing of Emperor Hirohito. As Prime Minister, he continued the strong pro-British, pro-American stance he held as Navy Minister and continued his strong opposition to the Tripartite Pact with Nazi Germany and fascist Italy.

Following the German occupation of the Low Countries and France in May–June 1940, the Imperial Japanese Army began to show dissatisfaction with Yonai's anti German policy. The disagreement became apparent in early July 1940, as Minister of War Shunroku Hata began to criticize the Prime Minister openly. Yonai was forced to resign on 21 July 1940, largely due to pressure from the pro-Axis Imperial Japanese Army. The Tripartite Pact was signed on 27 September 1940.

Subsequent political activity
Yonai served as Deputy Prime Minister and concurrently as Navy Minister again under the cabinet of Prime Minister Kuniaki Koiso from 22 July 1944, during which time he returned to the active duty roster from the reserve list. By this time, Saipan had fallen to the Allies.

Yonai remained Navy Minister under the administration of Prime Minister Kantarō Suzuki. In the last few weeks before Japan's surrender, he sided with Prime Minister Suzuki and Foreign Minister Shigenori Tōgō in support of acceptance of the Potsdam Declaration in opposition to Minister of War Korechika Anami, Chief of Naval General Staff Admiral Soemu Toyoda and Chief of the Army General Staff General Yoshijirō Umezu.

Yonai remained Navy Minister in the cabinets of Prime Minister HIH Higashikuni Naruhiko and Prime Minister Kijūrō Shidehara from August 1945, during which time he presided over the final dissolution of the Imperial Japanese Navy.

He played a major role during the International Military Tribunal for the Far East in working with the major defendants, such as Hideki Tōjō, to coordinate their testimonies so that Emperor Hirohito would be spared from indictment. According to his interpreter Suichi Mizota, in March 1946 Bonner Fellers asked him to make Tōjō bear all responsibility for the Greater East Asia War After the war, Yonai devoted rest of his life to help to rebuild devastated Japan.

Yonai suffered from high blood pressure most of his life, but he died of pneumonia in 1948 at the age of 68. His grave is located at the temple of Enko-ji in his hometown of Morioka.

Minister of the Imperial Japanese Navy (1937-1939)
Yonai was not verbal, however Yonai always had strong will when he spoke. Because of his work as a military attaché, and his travels around European countries, he had background knowledge. Yonai had already analyzed naval capabilities of the Imperial Japanese Navy and allied countries, the Third Reich and Italy. In addition, he participated in the Naval Battle of the Japanese Sea, a part of the Russo-Japanese war, as a Lieutenant so he knew the real naval battle. Hence, on August 8, 1939, at the five-ministry commission that was intended to make a plan for war, the minister of finance, Ishiwata inquired Yonai “Is it possible for the Imperial Japanese Navy to triumph over America and Britain?” (Agawa, n.d.). He articulated “No. The Imperial Japanese Navy is not designed to open fire against them. The Third Reich and the Italian Navy are out of question.” (Agawa, n.d.). Since the historical triumph of the Naval Battle of the Japanese Sea in 1905, as a part of the Russo-Japanese War, the Imperial Japanese Navy had been occupying the world’s 3rd strongest position. Even though, the Imperial Japanese Navy could not compete against the Royal Navy and the United States Navy, the top two Navies in the world. Consequently, the Third Reich Navy and the Italian Navy could not win these two dominants. Furthermore, the Imperial Japanese Navy had been so conceited because of the victory of the Naval Battle of the Japanese Sea that it was definitely difficult to admit its inferiority. However, his unique experiences made him convinced. Therefore, Yonai clearly announced his opinion: the Imperial Japanese Navy will lose if it opened fire on the Royal Navy and the United States Navy.

Pre-prime minister
Before he was chosen as the Prime Minister, Yonai showed strong leadership particularly in crisis. On the day February 26, 1936, a coup d’etat lead by young officers of the Imperial Japanese Army happened. The generals of the Imperial Japanese Army were struggled to decide the appellation of the rebellion troops. The generals were hesitant to call them as rebellion troops because it was extremely shameful for them to admit an internecine strife. In addition, one of the commanders of the rebellion troop was a son in law of the general. Hence, the generals were hesitant. On the other hand, Yonai, the commander-in-chief of the Sasebo Naval District, instantaneously labeled them as “Insurrectional troops,” (Agawa, n.d.) and let the chief of his staff, Admiral Inoue Shigeyoshi, publish his position to all the Sasebo Naval District. Because of this immediate announcement, navy officers in the Sasebo Naval District were compelled to stop participating the rebellion troops. Yonai’s prompt action as the supreme commander tranquilized the Sasebo Naval District.

Time as prime minister (January 16 to September 16, 1940)
Despite Yonai not being famous, he made significant decisions that depict his strong moral character. At his appointment as Prime Minister, he retired from active service of the Imperial Japanese Navy without being asked to. He intended not to control his cabinet ministers by naval influences. This verdict was momentous. Because once military personnel retires, he loses effects on the military, hence all the generals and admirals rebuffed to retire. Indeed, Tojo Hideki, the 40th Prime Minister did not retire at his promotion to Prime Minister. He persisted with active service in the Imperial Japanese Army to uphold his effects over it, and the cabinet participants. Because of Yonai’s retirement from the Imperial Japanese Navy, the Yonai Cabinet was cooperative. One prominent evidence of this was that: nevertheless his cabinet had continued just a half a year, his cabinet members and followers formed a friendly reunion right after his resign (year, 1937), and it still lasting in the Heisei period (1989–present). This reunion is named Ichi-Roku Kai. It means sixteenth gathering; because Yonai’s appointment and resignation as a Prime Minister were both happened on the 16th day of months.

The Emperor’s trust
Emperor Showa trusted Yonai’s strong moral character. On July 1944, the situation of the World War II was apparently against Japan. As for this difficult circumstance, the Imperial Japanese Navy was in a confusion. Supreme commanders of the Imperial Japanese Navy decided to appoint Yonai as the Minister of Navy because he had a popularity and charisma enough to unite the Imperial Japanese Navy; although Yonai had already retired from the navy. To assign Yonai as the Minister of Navy, the Emperor’s consent was necessary. Meanwhile, Admiral Suetsugu was also a candidate. The Emperor rejected Yonai because Suetsugu was famous for his ambition, and allowed only Yonai to be the Minister of Navy as an active service military person. This appointment depicted Showa’s trust on Yonai because he is the only one person in the Imperial Japanese Navy’s history to return from retirement and be posted to the supreme position of the Minister of Navy. After the Imperial Japanese Navy was defeated, the Emperor called Yonai to his castle. The Emperor amiably invited Yonai to have lunch together. After that, the Emperor said, "I really appreciated your reign and effort not to begin the war. I think we are not going to meet often like before". He put a pen and inkstone into a case and said, "These are the things that I have used. I would like to present this as a gift to you." (Agawa, n.d.). This action is extremely rare because having presented the belongings of the Emperor is the supreme honor and the utmost expression of amiability.
