A typical post picks up 162 interactions against 1.7M followers, an engagement rate of 0.01%. Measured over 90 original posts, its engagement rate beats 45% of 3,758 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end.

Compared with accounts its own size
東京都 防災's engagement rate beats 45% of the tracked X accounts closest to it in follower count (3,758 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 26% 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 0.01%, 東京都 防災 sits above the 10th percentile of the 36,654 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Posting timing
This account posts most often around 09:00 UTC, and Saturday 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.

- What is 東京都 防災's engagement rate on X?
- 東京都 防災 (@tokyo_bousai) has an engagement rate of 0.01%, based on the median interactions across 90 original posts from the last 30 days against 1,680,977 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.01%, 東京都 防災 sits above the 10th percentile of the 36,654 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 @tokyo_bousai have real engagement?
- Its engagement rate beats 45% of the tracked X accounts closest to it in follower count (3,758 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 @tokyo_bousai post?
- Most posts go out around 09:00 UTC, and Saturday is its busiest day, at roughly 4.33 posts per day across the measured window.
