Early life

Shūji Tsushima was born on June 19, 1909, the eighth surviving child of a wealthy landowner and politician
in
Kanagi, located at the northern tip of the

. He was the tenth of the eleven children born to his parents. At the time of his birth, the huge, newly completed
Tsushima mansion, where he spent his early years, was home to some thirty family members. The Tsushima family was of obscure peasant origins. Dazai's great-grandfather built up the family's wealth as a moneylender, and his son increased it further. They quickly rose in power and, after some time, became highly respected across the region.
Dazai's father, Gen'emon, was a younger son of the Matsuki family, which, due to "its exceedingly 'feudal' tradition," had no use for sons other than the eldest son and heir. As a result, Gen'emon was adopted into the Tsushima family to marry the eldest daughter, Tane. He became involved in politics due to his position as one of the four wealthiest landowners in the prefecture, and was offered membership of the
House of Peers. This caused Dazai's father to be absent during much of his early childhood. As his mother, Tane, was ill, Dazai was brought up mostly by the family's servants and his aunt Kiye.
Education and literary beginnings
In 1916, Dazai began his education at Kanagi Elementary. On March 4, 1923, his father Gen'emon died from lung cancer. A month later, in April, Dazai moved to Aomori Junior High School, followed in 1927 by Hirosaki Higher School, a

''. Around 1928, Dazai edited a series of student publications and contributed some of his own works. He also published a magazine called ''Saibō Bungei'' (''Cell Literature'') with his friends, and subsequently became a staff member of the college's newspaper.
Dazai's success in writing was brought to a halt when his idol, the writer

Shocked by the events, Dazai's family intervened to stop the police investigation. His allowance was reinstated, and he was released without any charges. In December, he recovered at Ikarigaseki and married Hatsuyo there.
Leftist movement
In 1929, when the principal of Hirosaki High School was found to have misappropriated public funds, the students, under the leadership of Ueda Shigehiko (Ishigami Genichiro), leader of the Social Science Study Group, staged a five-day strike, which resulted in the principal's resignation and no disciplinary action against the students. Dazai hardly participated in the strike, but in imitation of the proletarian literature in vogue at the time, he summarized the incident in a novel called ''Student Group'' and read it to Ueda. The Tsushima family was wary of Dazai's leftist activities. On January 16 of the following year, the Special High Police arrested Ueda and nine other students of the Hiroko Institute of Social Studies, who were working as activists for Seigen Tanaka's Communist Party.
In college, Dazai met activist Eizo Kudo, and made a monthly financial contribution of ten yen to the

. He was expelled from his family after his marriage to Hatsuyo Oyama in order to prevent any association of his illegal activities with his brother Bunji, who was a politician. After his marriage, Dazai was ordered to hide his sympathies and moved repeatedly. In July 1932, Bunji tracked him down, and had him turn himself in at the Aomori Police Station. In December, Dazai signed and sealed a pledge at the Aomori Prosecutor's Office to completely withdraw from leftist activities.
Early literary career

Dazai kept his promise and settled down. He managed to obtain the assistance of

In 1935 it started to become clear to Dazai that he would not graduate. He also failed to obtain a job at a Tokyo newspaper. He finished ''
The Final Years'' (''Bannen''), which was intended to be his farewell to the world, and tried to hang himself on March 19, 1935, failing yet again. Less than three weeks later, he developed acute appendicitis and was hospitalized. In the hospital, he became addicted to Pavinal, a morphine-based painkiller. After fighting the addiction for a year, in October 1936 he was taken to a mental institution, locked in a room and forced to quit

The treatment lasted over a month.
During this time Dazai's wife Hatsuyo committed adultery with his best friend Zenshirō Kodate. This eventually came to light, and Dazai attempted to commit ''

石原美知子). Their first daughter, Sonoko (
園子), was born in June 1941.
In the 1930s and 1940s, Dazai wrote a number of novels and short stories that are autobiographical in nature. His first story, ''Gyofukuki'' (魚服記, "Transformation", 1933), is a grim fantasy involving suicide. Other stories written during this period include ''Dōke no hana'' (道化の花, "Flowers of Buffoonery", 1935), ''Gyakkō'' (逆行, "Losing Ground", 1935), ''Kyōgen no kami'' (狂言の神, "The God of Farce", 1936), an epistolary novel called ''Kyokō no Haru'' (虚構の春, ''False Spring'', 1936) and the stories in the collection ''Bannen'' (1936; ''Declining Years'' or ''The Final Years''), which describe his sense of personal isolation and his debauchery.

Dazai's house was burned down twice in the

Postwar career

In the immediate postwar period, Dazai reached the height of his popularity. He depicted a dissolute life in postwar Tokyo in ''Viyon no Tsuma'' (ヴィヨンの妻, "Villon's Wife", 1947), depicting the wife of a poet who had abandoned her and her continuing will to live through hardships.
In 1946, Dazai published a controversial memoir, "Kuno no Nenkan" (Almanac of Pain), in which he describes the immediate aftermath of Japan's defeat and seeks to encapsulate how the Japanese felt at the time. Dazai reaffirmed his loyalty to the Japanese Emperor,

. However, Dazai also expressed his Communist beliefs in this memoir. Dazai also wrote ''Jugonenkan'' (''For Fifteen Years''), another autobiographical piece.

The disgust in which I hold Dazai's literature is in some way ferocious. First, I dislike his face. Second, I dislike his rustic preference for urban sophistication. Third, I dislike the fact that he played roles that were not appropriate for him.
Other participants at the dinner could not remember if events occurred as Mishima described. They did report that he did not enjoy Dazai's "clowning" and that he and Dazai had a dispute about

太田静子), an admirer of Dazai's work who first met him in 1941. The pair had a daughter, Haruko, (

A heavy drinker, Dazai became an alcoholic and his health deteriorated rapidly. At this time he met Tomie Yamazaki (
山崎富栄), a beautician whose husband had been killed in the war after just ten days of marriage. Dazai abandoned his wife and children and moved in with Tomie.
Dazai began writing his novel ''

Death

On June 13, 1948, Dazai and Tomie drowned themselves in the rain-swollen

At the time, there was a lot of speculation about the incident. Keikichi Nakahata, a kimono merchant who frequented the young Tsushima family, was shown the scene of the suicide by a detective from Mitaka police station. He speculated that "Dazai was asked to die, and he simply agreed, but just before his death, he suddenly felt an obsession with life."
