History

Customary Japanese units are a local adaption of the traditional Chinese system, which was adopted at a very early date. They were imposed and adjusted at various times by local and imperial statutes. The details of the system have varied over time and location in Japan's history. Japan signed the

in 1890. The next year, a weights and measurements law codified the Japanese system, taking its fundamental units to be the ''shaku'' and ''kan'' and deriving the others from them. The law codified the values of the traditional and metric units in terms of one another, but retained the traditional units as the formal standard and metric values as secondary. In 1909,

established a Committee for Weights and Measures and Industrial Standards, part of whose remit was to investigate which of Japan's three legal systems should be adopted. Upon its advice, the Imperial Diet established the metric system as Japan's legal standard, effective 1 July 1924, with use of the other systems permitted as a transitional measure. The government and "leading industries" were to convert within the next decade, with others following in the decade after that..

In 1933, the government pushed the deadline for the conversion of the first group of industries to 1939; the rest of the country was given until 1954. Emboldened, the nationalists succeeded in having an Investigating Committee for Weights and Measures Systems established. In 1938, it advised that the government should continue to employ the "Shaku–Kan" system alongside the metric one. The next year, the imperial ordinance concerning the transition to the metric system was formally revised, indefinitely exempting real estate and historical objects and treasures from any need for metric conversion. The deadline for compulsory conversion in all other fields was moved back to 31 December 1958. Following its defeat in

The Diet revisited the nation's measurements and, with the occupation's approval, promulgated a Measurements Law in June 1951 that reaffirmed its intention to continue Japan's metrication, effective on the first day of 1959. An unofficial and ''ad hoc'' Metric System Promotion Committee was established by interested scholars, public servants, and businessmen in August 1955, undertaking a public awareness campaign and seeking to accomplish as much of the conversion ahead of schedule as possible. Its first success was the conversion of candy sales in Tokyo department stores from the ''momme'' to the gram in September 1956; others followed, with

taking the lead in media use.. With the majority of the public now exposed to it since childhood, the metric system became the sole legal measurement system in most fields of Japanese life on 1 January 1959.. Redrafting of laws to use metric equivalents had already been accomplished, but conversion of the land registries required until 31 March 1966 to complete. Industry transitioned gradually at its own expense, with compliance sometimes being nominal, as in the case of screws becoming " screws".. Since the original fines for noncompliance were around $140 and governmental agencies mostly preferred to wait for voluntary conversion, metric use by December 1959 was estimated at only 85%.. Since research showed that individual Japanese did not intend to actually use the metric units when given other options, however, sale and verification of devices marked with non-metric units (such as rulers and tape measures noting ''shaku'' and ''sun'') were criminalised after 1961. Some use of the traditional units continues. Some Japanese describe their weight in terms of ''kan''. Homes continue to be reckoned in terms of ''tsubo'', even on the
