The one sen coin 一銭 was a Japanese coin worth one-hundredth of a Japanese yen, as 100 sen equalled 1 yen.https://books.google.com/books?id=mZ8FAAAAQAAJ&q=japanese+half+sen&pg=PA113 The British Almanac Stationers' Company John Crowdy 1873 112–113 December 9, 2016 One sen coins were first struck for circulation during the 6th year of Meiji's reign (1873) using a dragon design. The denomination had been adopted in 1871 but coinage at the time could not be carried out. Aside from an alloy change and a new rice stalk wreath design, one sen coins remained the same weight and size for the remainder of the era. The situation changed when World War I broke out under Emperor Taishō as rising metal costs led to a size and weight reduction. These smaller coins were first produced in 1916 with a paulownia design which was seen as liberal at the time. Emperor Shōwa took the throne in 1926, and Japan was pushed into a militaristic regime by the early 1930s causing metals to be set aside for wartime conditions. These effects would later impact one sen coins through numerous alloy, size, and design changes.
Bronze was the first alloy to be used for coinage which was replaced by brass, then aluminium in the span of a single year (1938). One sen coins were made lighter and were reduced in size as World War II raged on causing a demand for material to make military supplies. The last coins were produced from 1944 to 1945 using a tin and zinc based alloy as the situation further deteriorated. One sen coins were discontinued after the war, and were demonetized at the end of 1953 along with other subsidiary coinage.https://web.archive.org/web/20020628033108/http://www.shugiin.go.jp/itdb_housei.nsf/html/houritsu/01619530715060.htm http://www.shugiin.go.jp/itdb_housei.nsf/html/houritsu/01619530715060.htm June 28, 2002 小額通貨の整理及び支払金の端数計算に関する法律 A law of the abolition of currencies in a small denomination and rounding off a fraction, July 15, 1953 Law No.60 www.shugiin.go.jp December 5, 2016 Collectors now trade these coins on the market where their value depends on survivability rate and condition.

No coins were struck for circulation right away as the technology to mass-produce the coins was poor at the time. Silver and gold coins were thus given priority as they were produced and distributed to the market before copper coinage could be carried out.https://www.buntetsu.net/mbc/m001b.htm 1銭銅貨 Buntetsu October 16, 2020 One sen coins were eventually introduced on August 29, 1873, via government notification. Each coin was authorized to be struck in an alloy of copper, weighs 110 grains (7.13g), and has a 1.10 inch diameter (27.9mm).https://books.google.com/books?id=6RlDAQAAIAAJ&q=1+sen+coin+98+copper&pg=PA745 The Japan Daily Mail 4 1874 745https://books.google.com/books?id=i9YqAAAAYAAJ&q=%221+sen%22+weight+grains&pg=RA3-PA275 Monetary System of Japan Report and Accompanying Documents of the United States Monetary Commission, Organized Under Joint Resolution of August 15, 1876 U.S. Government Printing Office 2 1877 276 Obverse features on the first one sen design include a dragon with the date of reign, and "1 sen" written in English. Reverse features include the value "1 sen" (written in Kanji) centered inside a wreath design. The Chrysanthemum seal is located at the top of the coin flanked by the words "100 for one yen" in Kanji. These coins were legal tender only up to the amount of 1 yen which was fixed by government regulations.https://books.google.com/books?id=GbgpAAAAYAAJ&q=one+sen+coin+1878&pg=PA2264 Commercial Notes Monthly Summary of Commerce and Finance of the United States U.S. Government Printing Office 1900 2264
Production continued for a few years before it was stopped as no coins are dated from year 11 or 12 (1878 and 1879). It is theorized that the aftermath of the Satsuma Rebellion could have left an impact.http://pepper.cool.coocan.jp/round/ryu_1sen_dou.htm 竜一銭銅貨 Pepper's Square October 16, 2020 When production resumed in 1880 (year 13), the scales on the obverse dragon design were changed from a square to a V-shaped pattern.http://archives.pref.yamaguchi.lg.jp/user_data/upload/File/smallexhibition/H26-01.pdf Shifting of Modern Currency Yamaguchi Prefectural Archives October 16, 2020 This slightly modified first one sen design continued to be minted until 1888 (year 21), when coinage was stopped due to mass production and a slight oversupply.

One sen coins were minted again during Emperor Shōwa's 2nd year of reign (1927) using the Taishō era paulownia design. Meanwhile, events around the world including the Great Depression were leading up to another world war. Japan was pushed into a militaristic regime by 1933, and started stockpiling nickel as war materials.New Revised Money Notebook, History and Collection Guide for Japanese Coins Reiji Aoyama Bonanza 1982 192–193 The Second Sino-Japanese War broke out in 1937 and a National Mobilization Law was declared in the following year.Pauer Erich 1999 Japan's War Economy Routledge 0-415-15472-3 13 This action suspended the coinage act of 1897 and allowed the Japanese government to issue temporary subsidiary coins without obtaining approval from the Imperial Diet.New Revised Money Notebook, History and Collection Guide for Japanese Coins Reiji Aoyama Bonanza 1982 193–195 New brass coins featuring a crow design on the obverse replaced the old copper paulownia coins on June 1, 1938.https://books.google.com/books?id=tu1VY7zA5CQC&q=Japan+sen+coin+1938&pg=PA76 Money, Banking, and Credit Civil Affairs Handbook: Taiwan (Formosa) Economic Supplement Office of the Chief of Naval Operations (US Navy) United States Department of the Navy 1944 76 Brass was chosen as the previous composition contained tin which was a military-important metal not produced in Japan.http://pepper.cool.coocan.jp/round/1sen_oudou.htm 一銭黄銅貨(カラス1銭黄銅貨)Crow 1 Sen (Blass) Pepper's Square Japanese October 26, 2020 The "crow" design with waves on the obverse, and eight ridge mirrors on the reverse was made by combining submissions from a public offering.

By using aluminum, one sen coins were produced in large amounts as the alloy is naturally soft, did not require annealing, and extended the life of the dies.

This feature was allegedly handwritten by Isao Kawada, who was the minister of finance at the time. The diameter of the coin was also reduced from 17.6 to 16mm while the weight dropped from 0.90 to 0.65 grams. In April 1943 the Japanese government announced plans to use tin in coinage as aluminum was needed for more aircraft.https://books.google.com/books?id=smwn2UxgD8YC&q=Japan+one+sen+coin+1941&pg=PA102 Currency and Money Transfers Currency Standard and Circulating Media Civil Affairs Handbook United States Army 1943 102 This shift did not happen right away as one sen coins had their aluminum content dropped from 0.65 to 0.55g that year. However, as World War II dragged on the amount of available aluminum was eventually depleted.
Tin and zinc replaced aluminum for one sen coins when they were issued in March 1944. The final design used for these coins features a chrysanthemum crest with value on the obverse, and inscriptions on the reverse. Although tin was not an ideal choice for money as the metal is heat-sensitive and soft, the Japanese government had no alternatives.https://www.buntetsu.net/mbc/cmc001-3.htm 1銭錫貨 www.buntetsu.net Japanese March 28, 2018 Supplies of tin were available at the time from occupied Southeast Asia where the metal was abundantly produced.

Shōwa era designs
Five different designs were used during the Shōwa era for the 1 sen coin, not including pattern coins which were never intended for circulation. As the weight and sizes were changed frequently after 1937, these designs have been listed separate with their respective information.

All of these except one sen coins have two varieties made during 1877 as the scales were changed from a square to a "V" shape pattern. One sen coins received the change in 1880, and there is little difference in value when it comes to the design of the dragon's scales.https://coinquest.com/cgi-bin/cq/coins.pl?coin=9543 Japan 1/2, 1, and 2 Sen 1873 to 1892 Coin Quest October 30, 2020 The next rice wreath design (1898 to 1915) spanned two imperial eras.

The most valuable of these coins are dated from 1900 and 1902 (year 33 and 35). Finally, one sen coins with the paulownia design (1916 to 1938) have a single key date with 1930 (year 5 of Shōwa). The one sen coin eventually received a crow design in 1938 and production increased until the series ended in 1945. Collecting these later dates remains affordable as there are plenty of surviving coins.
