Original comparison dataset
How unusual is Psyren's 16-year wait?
Long, but not unprecedented. These five documented Weekly Shonen Jump cases span 10–23 calendar years from manga completion to the first screen anime identified in the reviewed official sources.

The comparison
“Gap” means anime start year minus manga end year. It is a calendar comparison, not an exact elapsed duration or a complete history of every Jump adaptation.

What these rows establish
01
Psyren is not an isolated case
Its 16-year calendar gap sits between the selected minimum of 10 and maximum of 23 years.
02
Format still matters
Four examples began as television series; Sand Land entered through a theatrical film before its later streaming series.
03
The table does not prove a market trend
Five selected examples can establish precedent. A trend claim needs a complete denominator and a time-series census.
Method and limits
- Use the Japanese manga completion year documented by a publisher or creator record.
- Use the first screen-anime year and format documented by a broadcaster, distributor, or production record in the reviewed source set.
- Calculate calendar_year_gap as anime_start_year minus manga_end_year; do not present it as an exact elapsed duration.
- Keep television and theatrical adaptations distinct and retain a claim-level note for every row.
- Recheck source availability and the Psyren premiere record before quoting this dataset after October 2026.
Selected documented examples, not a complete census of Weekly Shonen Jump history. Remakes of manga already animated, manga first animated while still running, continuations, games, audio dramas, and cases without enough official evidence for both endpoints.
