I couldn’t verify a reliable public count of 8th dan kendoka in Mexico from the information available here. The broader kendo data I found only shows that 8th dan is extremely rare globally, with 466 holders reported in one dataset from January 2003.

What can be said safely

  • Mexico does have an active kendo community, but I didn’t find a trustworthy source that lists the number of Mexican 8th dan holders specifically.
  • Because 8th dan is the highest exam-based rank in kendo, the number in any single country is usually very small.
  • A precise figure would need an up-to-date roster from the Mexican kendo federation or an official regional grading record.

Best cautious answer

A defensible answer is: probably only a handful, but I can’t confirm the exact number from the sources available.

Source note

The global reference point I found reports 466 total 8th dan holders in January 2003, which helps show how rare the rank is, but it does not break the number down by country.
