Construction Statistics: May 2026 Released

The Construction Comprehensive Statistics are processed statistics used to measure construction activity in Japan on a work-completed basis. Based on construction costs from the Building Start Statistics Survey and the Construction Orders Dynamics Statistics Survey, they estimate the conversion of start-based amounts into monthly completed construction work.

The edition published this time covers May 2026 and can be accessed through e-Stat, the government's portal for official statistics.

These statistics are used to measure construction activity in Japan on a work-completed basis.

Because the figures published this time may change in the future, they should not be treated as fixed final values when used. They may be retrospectively revised as adjustment rates are applied and the quality of the underlying statistics improves.

In the estimation process, construction costs measured on a start-based basis are converted into monthly completed work according to project progress.

When the April figures are published every June, the latest adjustment rate calculated from confirmed actual construction investment is applied, and the figures are retrospectively revised for the past three years from the preceding March figures.

Retrospective revisions may also be made for reasons other than those described above, in response to quality improvements in the underlying statistics and other data. Users should refer to the “Usage Notes and New and Old Information” when using the statistics.
