Kaomoji Copy Usage Reports — methodology and archive
kaomojis.jp records, anonymously, when a visitor presses a copy button. We publish this primary data for each completed calendar month in a reusable form.
Published reports
Definitions
- Recorded copy-button events
- The number of times a copy button on the site was pressed. It excludes OS-level copying, copying by text selection, and any use on other sites or apps.
- Anonymous sessions
- The number of distinct random identifiers assigned per browser. **These are not unique users.** One person using several devices or browsers is counted separately, and a cleared identifier is counted again.
- Distinct kaomoji
- The number of kaomoji copied at least once during the period.
- Interface language
- The language of the page where the event was recorded, derived from the URL prefix. It does not indicate the user’s country of residence, nationality, native language, location, or device language setting.
Methodology
- Date boundaries are UTC. Only completed calendar months are published; partial months are not.
- Automated traffic is excluded from measurement by a client-side check. Because the check runs client-side, it has limits.
- Repeated copies of the same kaomoji within one session are counted each time; no de-duplication is applied.
- Simplified Chinese pages (zh) and Traditional Chinese pages (zh-TW) are reported separately, not merged.
- Events whose interface language cannot be determined are counted as “unknown” rather than dropped, so the per-language figures sum to the total.
- For languages with fewer than 100 events in a month, rankings are withheld because they would be unstable.
- Only aggregates are published. Session identifiers and individual event timestamps are not released.
Known limitations
This data is a complete count of copy-button events among visitors to kaomojis.jp. It is not a representative sample of internet users. The results therefore describe selection and copying behaviour observed within this site, not kaomoji usage rates in the general population. Changes in totals are strongly affected by changes in site reach and cannot be read as changes in demand.
