防衛省・自衛隊 engagement report
@ModJapan_jp - 1.3M followers on X
Measured over 23 original posts from a 30-day window, last computed on August 23, 2026.
Engagement
A typical post picks up 1.3K interactions against 1.3M followers, an engagement rate of 0.099%. Measured over 23 original posts, its engagement rate beats 77% of 983 tracked accounts of a similar size. Comparing inside a size band matters here: engagement rate falls as accounts grow, so a raw rate would mostly just re-measure the follower count. Posts are seen about 54K times each, and 2.31% of those impressions turn into an interaction. That is about 4.30% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.1 posts a day over the last 30 days, though only 23% of days saw any activity at all. Most posts go out around 08:00 UTC, and Friday is the busiest day of the week. Of the 23 posts sampled, 70% carry an image or video and 43% link out. The account's strongest tracked post pulled 4.5K interactions, about 3.6x its own typical post. Recurring topics include #防衛省・自衛隊, #警戒監視・情報収集, #緊急発進.

Compared with accounts its own size
防衛省・自衛隊's engagement rate beats 77% of the tracked X accounts closest to it in follower count (983 accounts, accounts of similar size (decile 6 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 77% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

At 0.099%, 防衛省・自衛隊 sits above the 50th percentile of the 9,668 accounts in this comparison. That places it in the above the median band, which runs 0.046% to 0.318%.

Posting timing
This account posts most often around 08:00 UTC, and Friday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 70% of posts | +79% | +73% to +84% | 5.7K |
| Outbound link | 43% of posts | -49% | -50% to -47% | 6.0K |
| Typical length | - | +12% | +10% to +15% | 6.3K |
- 70% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 79% above the same accounts' other posts.
- 43% of its posts carry a link off X. Across the catalog, posts with an outbound link run 49% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 351 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 12% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.
