Because the text is inconsistent–both "Takeshi Tatsuo" and "Tatsuo Takeshi" are used in the story text. And this makes sense&mdash;it is conventional Western practice to analyze Japanese names and reverse the name order when speaking in English&mdash;it is only TMNT series convention that "Hamato Yoshi", "Oroku Saki" and such are exempt&mdash;otherwise they would be "Yoshi Hamato" and "Saki Oroku". Even in Amazing Adventures' Quiet Please, when is writing cute little notes in his work notebook, he adds a little heart with the initials A.O. and D.H.&mdash;April O'Neil and Donatello Hamato. Donatello is a westernized person and switches the name order for himself.

References: No, "" is also a very common Japanese masculine given name. But is not a surname. (Not that this matters too much, as modern Japanese naming practice only dates back to the 19th century, making many of the feudal Japan names anachronistic anyway.)
