Japan

The Wikipedia article on Japan has been edited 20,639 times since it was created in 2001, by 6,260 distinct accounts and IP addresses. That averages about 828 recorded changes a year, or several every day, which puts it among the more actively maintained pages on the encyclopedia.

Within the revisions retrieved for this report, the ten busiest contributors account for about 49% of the changes, with the rest spread across a long tail of occasional editors. That is a fairly typical mix of regular maintainers and passing corrections.

Within the retrieved window, 2025 carries the most recorded activity, with 279 changes. 32 of those revisions fall in the last 90 days. The most recent recorded edit was 27 days ago.

Readership has been broadly stable across the last two years of pageview data. The clearest peak in that record falls in July 2025. Traffic spikes and editing spikes often line up, but the revision record alone cannot tell you which one caused the other, or whether an outside event drove both.

This report is built from the 500 most recent revisions retrieved from Wikipedia, about 2% of the 20,639 recorded edits. Figures drawn from that window describe the window only, and the report cannot establish why a change was made or whether it was correct.
