Because let's just face it, the name Karai is just a reminder of the way Shredder treated her; as a means to destroy her true father. (Karai is japanese for weapon.) Well, "karai" means multiple things, including "spicy", "harsh", "painful", "cyclonic thunderstorm" and "flower bud".

Note that Nickelodeon did not originally name her:

The was introduced in Mirage TMNT in the early 1990s, and she was daughter to neither Splinter nor the Shredder. She was originally the leader of the world Foot Clan organization, and the Shredder was a rogue subordinate who broke off his New York City division from the main organization. Karai was even old enough to have a teenage daughter of her own.

"Hamato Miwa" is entirely original to Nickelodeon TMNT.
