The 1000 yen note (¥1000) is currently the lowest value yen banknote and has been used since 1945, excluding a brief period between 1946 and 1950 during the American occupation of Japan. The fifth series (series E) notes are currently in circulation having been introduced on November 11, 2004 and are the smallest of the three common bank notes measuring 150 x 76 mm. The front side shows a portrait of Hideyo Noguchi, a bacteriologist who devoted himself to yellow fever research. The reverse depicts Mount Fuji and cherry blossoms.
Extensive anti-counterfeiting measures are present in the banknote. They include intaglio printing, holograms, microprinting, fluorescent ink, latent images, watermarks, and angle-sensitive ink.
The first ¥1000 note was released on August 17, 1945. At the time each series of bank note was labelled series 甲, 乙, 丙, 丁 or い, ろ as opposed to series A, B, C, D, E.  It measured 172 x 100 mm and featured images of the legendary prince Yamato Takeru and the Shinto shrine Takebe taisha. It was removed from circulation on March 2, 1946.
A series A bank note was never released in 1946 along with other bank notes.
The series B note measured 164 x 76 mm and entered circulation on July 1, 1950. The obverse displayed an image of the semi-legendary regent and politician under Empress Suiko, Prince Shōtoku. The reverse side contained an image of the "Yumedono" (literally Hall of Dreams) in the grounds of Hōryū-ji, a Buddhist temple located in Nara Prefecture. Only one version of the bank note existed and was removed from circulation on January 4, 1965.
Like its predecessor, the series C note measured 164 x 76 mm and entered circulation on November 1, 1963. The obverse side contained a portrait of Itō Hirobumi, who, under Emperor Meiji, was the first Prime Minister of Japan assuming office in 1885. The reverse side displayed an image of the Bank of Japan. The series C note was released with the bank number in two different colours: black (from 1963) and blue (from 1976). It was removed from circulation on January 4, 1986.
The series D note, like the series E note currently in circulation, measured 150 x 76 mm and entered circulation on November 1, 1984. The obverse side contained a portrait of the Meiji period novelist Natsume Sōseki whose famous works include I Am a Cat and Kokoro. The reverse side featured two Red-crowned Cranes. The series D note was released with the bank number in four different colours: black (from 1984), blue (from 1990), brown (from 1993) and green (from 2000). With series E being brought into circulation in 2004, the series D notes were removed from circulation on April 2, 2007.
