Yudai is not on the 2022 record for Mexico City, where small counts are withheld at source.
The count never rose above 3 in a year, too few to chart.
Civil-registry acts in Mexico City by registration year. Counts are lower bounds (names under 6 in a month and borough are removed at source) and count name-instances, not people; compound names are split, so “Maria Jose” counts under each part. 2023, a partial extract through 3 Mar with no cell on record for this name, is excluded.

Not on the record in Spain, Argentina, Puerto Rico, England and Wales, Canada, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years. Not on the Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only). Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
