Measured over 35 original posts from a 30-day window, last computed on October 7, 2026.
Engagement
A typical post picks up 391 interactions against 347K followers, an engagement rate of 0.113%. Measured over 35 original posts, its engagement rate beats 73% of 20,444 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 42K times each, and 0.922% of those impressions turn into an interaction. That is about 12.2% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.3 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 07:00 UTC, and Tuesday is the busiest day of the week. Of the 35 posts sampled, 89% carry an image or video and 20% link out. The account's strongest tracked post pulled 17K interactions, about 44x its own typical post. Recurring topics include #メメントモリ, #hina, #坂本櫻.

Compared with accounts its own size
【4周年記念】メメントモリ公式's engagement rate beats 73% of the tracked X accounts closest to it in follower count (20,444 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 45% 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 0.113%, 【4周年記念】メメントモリ公式 sits above the 25th percentile of the 204,956 accounts in this comparison. That places it in the below the median band, which runs 0.024% to 0.143%.

Posting timing
This account posts most often around 07:00 UTC, and Tuesday 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 | 89% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 20% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | -3% | -3% to -2% | 54K |
- 89% 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.
- 20% 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 149 characters, which falls in the 80 - 180 characters band. Across the catalog, posts of 80 to 180 characters run 3% below 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.

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.
Recurring topics
The most frequent hashtags in the sampled posts. They describe what this account writes about; they are not a performance signal, and the catalog-wide breakdown on the hub shows how little hashtag count moves.

Reading these numbers
A typical post picks up 391 interactions against 347K followers, an engagement rate of 0.113%. Measured over 35 original posts, its engagement rate beats 73% of 20,444 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 42K times each, and 0.922% of those impressions turn into an interaction. That is about 12.2% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 1.3 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 07:00 UTC, and Tuesday is the busiest day of the week. Of the 35 posts sampled, 89% carry an image or video and 20% link out. The account's strongest tracked post pulled 17K interactions, about 44x its own typical post. Recurring topics include #メメントモリ, #hina, #坂本櫻.
- What is 【4周年記念】メメントモリ公式's engagement rate on X?
- 【4周年記念】メメントモリ公式 (@mementomori_boi) has an engagement rate of 0.113%, based on the median interactions across 35 original posts from the last 30 days against 347,188 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.113%, 【4周年記念】メメントモリ公式 sits above the 25th percentile of the 204,956 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 @mementomori_boi have real engagement?
- Its engagement rate beats 73% of the tracked X accounts closest to it in follower count (20,444 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 @mementomori_boi post?
- Most posts go out around 07:00 UTC, and Tuesday is its busiest day, at roughly 1.3 posts per day across the measured window.
