About the name Jiraiya
Jiraiya belongs to the English & American tradition. Its roots are documented, even though its precise meaning is not recorded in the standard references — an honest gap we prefer to a confident guess.
In the United States, Jiraiya first appears in Social Security records in 2007. It climbed to its best-ever rank of #735 in 2023, and in 2024 252 babies received the name — 2,044 in total since 1880. Those are the official counts, not estimates.
