(Note) 
Data source is "The Special Survey of the Labour Force Survey" from 1984 to 2001, "Labour Force Survey (Detailed Tabulation)" since 2002. Because there is difference such as survey methods and reference period, attention need to be paid to the time series comparison.

Concerning historical data
 Concerning the data on Jan.Mar. 1953, attention needs to be paid when time series comparison because these figures are on the effects of the sampling frame reform in 195253.
 "*" indicates that Okinawaken is not included in the figures (January 1953June 1972).
 The data prior to January 1978 are the compatible timeseries data that are adjusted to the effects of the methodological reform in 1967 and the benchmark revision in 1975. On this account, the data prior to 1978 is different from the data of the annual report published in each year.
 Using the latest results of the Population Census as the base, the Population Estimates are revised every five years according to the release of new results of the Census conducted quinquennially. Therefore, the benchmark population for calculating the results of the Labour Force Survey is revised every five years.
It has been revised to the 2010 Censusbased population estimates in January 2012. Population difference, 2010Censusbase benchmark of 15 years old and over for January 2011 minus that of 2005base, is approximately +690 thousand.
cf. Sampling Method, Estimation Method, and Sampling Errors of Estimates (PDF:95KB)
In order to remove the gaps, data from October 2005 through December 2011(italicized figures in red) have been adjusted to comparable timeseries data(the intercensallevel adjustment data, the retroactive adjustment data) responding to the revision.
cf. 2012 revision of benchmark population
 Concerning the regional results, the figures prior to 1983 are not available.
 Due to the Great East Japan Earthquake, results for whole Japan and Tohoku are missing from March through August 2011. So "Supplementaryestimated figures" have been used. "< >" indicates that supplementary estimated figures (Referential figures).
Concerning seasonally adjusted figures
 Seasonally adjusted figures are calculated by removing seasonal components from the original series, using the U.S. Census method (X12ARIMA (sigmalim = (9.8, 9.9)). Further explanation on seasonal adjustment is described in Seasonal Adjustment  X12ARIMA 
 The data carried for seasonal adjustments are the original series represented in this table. The data excluding Okinawaken prior to July 1972 and the data including Okinawaken since July 1972 are used for the seasonal adjustments.
Due to the Great East Japan Earthquake, results for whole Japan are missing from March through August 2011. So "Supplementaryestimated figures" are inputted for computing seasonal factors.
 The seasonally adjusted figures released monthly are calculated by using the predicted seasonal factors, which are estimated through seasonal adjustments of the data up to December of the previous year. On the release of January results, the seasonal adjustments are computed retroactively by adding new data for twelve months of the previous year.
 Concerning the seasonally adjusted figures for unemployed person and unemployment rate aged 65 years old and over, figures for males and females are not computed.
Others
 In the Labour Force Survey results, the number of employed persons is classified by the Japan Standard Industrial Classification (JSIC). With the 12th revision of the JSIC, the Statistics Bureau started providing the Labour Force Survey results by the new industrial classification from January 2009 results, and computed 20072008 results retroactively. As for the data till 2006, figures of industries which have no or small influence by the revision are shown. And retroactiveestimated figures, which were calculated in a simple way, of industries which have big influence by the revision are shown with parentheses "( )" as a reference.
Please refer to "Revision of industrial classification for the Labour Force Survey results"(PDF:59KB).
 Concerning the number of unemployed persons by reason for seeking a job, the figures prior to 1984 are not available. Because the selection of reasons for seeking a job was changed and subdivided from January 2002, attention needs to be paid when time series comparison.
