Jiroemon Kimura

According to records, Kimura, then named Kinjiro Miyake (三宅 金治郎, Miyake Kinjirō), was born on 19 April 1897^[1] in the fishing village of Kamiukawa, in the Kyoto Prefecture of the Empire of Japan, as the fifth of eight children to farmers Morizo Miyake (1858–1935) and Fusa Miyake (1867–1931);^[7][5] Kinjiro had two elder sisters (born 1 November 1887 and 11 December 1889 respectively) and two elder brothers (born 21 March 1892 and 20 February 1895 respectively), of whom, however, only the second sister and second brother were living at the time of Kinjiro's birth. His second brother (who died on 2 July 1986), as well as his younger sister (born 3 January 1900, who died on 18 April 1993) became at least 90 years old, his elder sister (who died by 1986) lived to age 96 and his youngest brother Tetsuo (born 4 March 1909) lived to age 98.

Kimura's age was further verified by researchers in an article that they published in 2017.^[7] After thorough research, including conducting family interviews and searching official records, the authors verified Kimura's age and date of birth.^[7] Kimura's nephew Tamotsu Miyake said his uncle's birthday was 19 March, but that this had been mistakenly recorded as 19 April in 1955 when records from neighbouring towns were consolidated and redone.^[5] The researchers concluded, however, that Kimura was listed as being born on 19 March 1897 (as opposed to 19 April 1897, his likely true birth date), on his school records due to his parents' desire to have him begin school a year earlier than his later birthday would have allowed, so that he could graduate from school earlier and begin working on the family farm.^[7] During this time in Japan, schoolchildren born before April were one school year ahead of schoolchildren who were born in April or afterwards.^[7]

On 1 April 1903, Kimura (then Kinjiro Miyake) began his primary-school education. An intelligent student, he graduated with the equivalent of an eighth-grade education under the old imperial educational system on 31 March 1911, having had two additional years of schooling beyond what was then compulsory.^[7]

After leaving school at the age of 14 he worked for the post office, retiring more than fifty years later at the age of 65. He then went on to work as a farmer until he was 90.^[8]

On 10 April 1911, Miyake began work at the Nakahama post office as a telegraph boy while also working on his family's farm. He left the Nakahama post office on 2 February 1913.^[7] From May to December 1914, he studied at a posts and telegraph training school in Kyoto, graduating at the head of his class of 70 students and resuming work at the Nakahama post office on 4 December 1914.^[7]

On 1 April 1918, Miyake was conscripted into the Imperial Japanese Army and was posted to Nakano, Tokyo, where he served with a communications unit. He was discharged from service on 30 June, was again conscripted on 1 September 1919 and was posted to Tokyo, but only served for three weeks until 21 September.^[7] On 23 May 1920, he left the Nakahama post office for the final time. To help support his second-youngest brother (1902–1987/1988) who had emigrated to Korea under Japanese rule for work and had fallen ill there, Miyake moved to Keijō (now Seoul, South Korea), taking a job on 31 May with the Government-General of Chōsen in the Mail and Telecommunications Department, with a salary of 30 yen plus a 30% overseas service allowance. He only stayed in Korea until November, however, before returning to Japan and his work on the farm.^[5][7]

From 1 to 21 September 1921, Kimura (formerly Miyake) underwent a final three-week period of army service, again in a communications unit, during which he was posted to Hiroshima. Around this time, he attended a ceremony in Kyoto to welcome the return to Japan of Crown Prince Hirohito from a tour of Europe.^[7] After his national service, Kimura resumed farming until 21 April 1924, when he was appointed a deputy postmaster at the Hira post office. He worked there for the next 38 years until his retirement on 30 June 1962, two months after his 65th birthday and having worked in post offices for 45 years.^[5][7]

On 27 December 1920, Kimura (then still Kinjiro Miyake) married his neighbor Yae Kimura (born 19 January 1904), the adopted daughter of Jiroemon Kimura VIII and his wife K. Kimura (1870–1939). The marriage was officially registered two days later.^[7] Since his wife's family lacked a male heir, he changed his name to Jiroemon Kimura, becoming the ninth member of the family to bear that name after his adoptive father-in-law's death in 1927.^[5] Jiroemon and Yae Kimura, who were married until Yae's death on 30 May 1979, had eight children born between 1922 and 1943, the second of whom, however, died on 10 August 1927, twenty days before age 2, and the youngest (born 8 December 1943) subsequently died on 31 August 1998 at age 54.^[7]

In 1978, Kimura and his wife moved in with their eldest son and his family. After Yae's death in late-May 1979, Kimura continued to live with his eldest son (born 12 May 1922) and subsequently, after the eldest son's death on 27 September 1998, with one grandson (born 1952/1953) until his death in 2005 and, for the remainder of his life, with the grandson's widow and, until January 2013, also with the eldest son's widow (the eldest son's widow died in early-2013 at age 83).^[9] Kimura had in total 14 grandchildren (of whom one grandson died in 2005) and 25 great-grandchildren,^[10][11] and his 13th great-great-grandchild was born in 2011, eleven months before Kimura's 115th birthday. At age 110, Kimura also had one living brother, Tetsuo, who died on 2 June 2007 at age 98.

After retiring, Kimura helped his eldest son run the family farm until he turned 90.^[12] He was health-conscious and active.^[13] He woke up early in the morning and read newspapers with a magnifying glass.^[13] He also enjoyed talking to guests and following live parliamentary debates on television. He credited eating small portions of food (hara hachi bun me) as the key to a long and healthy life.^[13][14]

Kimura was admitted to hospital for pneumonia on 11 May 2013, from which he recovered. However, his health started worsening again in early June 2013, as his blood sugar level, urine production and response declined. Kimura died of natural causes in a hospital in his hometown of Kyōtango, western Japan, at 2:08 a.m. on 12 June 2013,^[11][20] and was succeeded as the world's oldest living man by Salustiano Sánchez (born 8 June 1901), and as the oldest living person by fellow Japanese citizen Misao Okawa of Osaka (who was 320 days younger).
