In Naruto, the Uchiha clan was wiped out by Itachi, which makes sense why you don't see many Uchihas in the show. However, why do I hardly see anyone anyone in the show with the last name of Senju? The last time I recalled, they weren't wiped out by anything. What's up with that?
Note: I know that the Narutopedia page for the Senju Clan gives a short explanation, but I would like further elaboration.
