防衛省・自衛隊 engagement report
@ModJapan_jp - 1.3M followers on X
Measured over 74 original posts from a 30-day window, last computed on October 7, 2026.
Engagement
A typical post picks up 1.2K interactions against 1.3M followers, an engagement rate of 0.095%. Measured over 74 original posts, its engagement rate beats 72% of 15,519 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 56K times each, and 2.15% of those impressions turn into an interaction. That is about 4.44% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 02:00 UTC, and Friday is the busiest day of the week. Of the 74 posts sampled, 91% carry an image or video and 23% link out. The account's strongest tracked post pulled 18K interactions, about 15x its own typical post. Recurring topics include #防衛省, #防衛省サイバーコンテスト, #陸上自衛隊.

Compared with accounts its own size
防衛省・自衛隊's engagement rate beats 72% of the tracked X accounts closest to it in follower count (15,519 accounts, accounts of similar size (decile 10 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 71% 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.
Where this sits in the catalog
At 0.095%, 防衛省・自衛隊 sits above the 25th percentile of the 156,027 accounts in this comparison. That places it in the below the median band, which runs 0.022% to 0.127%.

Posting timing
This account posts most often around 02:00 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 | 91% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 23% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 91% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 23% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 183 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
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.

Reading these numbers
A typical post picks up 1.2K interactions against 1.3M followers, an engagement rate of 0.095%. Measured over 74 original posts, its engagement rate beats 72% of 15,519 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 56K times each, and 2.15% of those impressions turn into an interaction. That is about 4.44% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 6.9 posts a day over the last 30 days, with activity on almost every day in the window. Most posts go out around 02:00 UTC, and Friday is the busiest day of the week. Of the 74 posts sampled, 91% carry an image or video and 23% link out. The account's strongest tracked post pulled 18K interactions, about 15x its own typical post. Recurring topics include #防衛省, #防衛省サイバーコンテスト, #陸上自衛隊.
- What is 防衛省・自衛隊's engagement rate on X?
- 防衛省・自衛隊 (@ModJapan_jp) has an engagement rate of 0.095%, based on the median interactions across 74 original posts from the last 30 days against 1,265,070 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.095%, 防衛省・自衛隊 sits above the 25th percentile of the 156,027 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @ModJapan_jp have real engagement?
- Its engagement rate beats 72% of the tracked X accounts closest to it in follower count (15,519 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @ModJapan_jp post?
- Most posts go out around 02:00 UTC, and Friday is its busiest day, at roughly 6.93 posts per day across the measured window.
