Source-derived summary

The 10 sen coin (十銭硬貨) was a Japanese coin worth one tenth of a Japanese yen, as 100 sen equalled 1 yen. These coins were minted from the late 19th century up until the end of World War II.

History

Meiji coinage (1870–1912)

Ten sen coins were first struck towards the end of 1870 (year 3 of Meiji) from a newly established mint at Osaka. Initially, this process was done by engineers from the United Kingdom as Japan did not have the technology or raw materials to manufacture new coins. Authorization was given to strike ten sen coins in .800 silver, weighs 38.6 grains (2.5g), and has a 18.28mm diameter (0.72 in). The first design used is nicknamed rising sun dragon (旭日竜, Asahi Ryu), which had its features engraved by a commission of Japanese artists. The obverse side features a dragon with an open mouth, while on the reverse there is a paulownia decoration with a sunburst in the center, and the chrysanthemum seal up on top. While dated 1870 (year 3), these first year ten sen coins were not released into circulation until the following year (1871). During this time, the coins along with twelve other denominations were adopted by the Meiji government in an act signed on June 27, 1871. This newly adopted coinage gave Japan a western style decimal system based on units of yen, which were broken down into subsidiary currency of sen, and rin. Ten sen coins were set as legal tender only up to the amount of 10 yen which was fixed by government regulations.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as former Japanese coin. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 23, 2026. The linked authority identifier is Q28154548. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1870, 1912 and 1871.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
