what is the name of tanjiro's son

Tanjiro Kamado does not have a son in the canon Demon Slayer story. The series ends with a time skip showing descendants of the original characters, not Tanjiro’s direct son specifically.

What people often mean

The ending chapter introduces modern-era descendants, including characters like Kanata Kamado , who is part of Tanjiro’s far-future family line, but that is not the same as naming Tanjiro’s son.

Simple answer

• Tanjiro’s son: not officially named in canon, because he is not clearly presented as having a son in the main story.

• Known descendant: Kanata Kamado appears much later as a descendant in the family line.

Note

Some online posts confuse Tanjiro’s descendants with his children, so the safer answer is that there is no confirmed son name for Tanjiro in the original story.
