First off, we don't have the N1K1-Jc or any other N1K1 type or the N1K2-Ja, we have the N1K2-J.
Second, both the N1K1-Jc and the N1K2-Ja were the fighter-bombers of the George types and had additional racks under the wings for additional bombs (4x 250kg), while the N1K2-J was the land based interceptor variant and not equipped with additional bomb and only carried 2x 250kg bombs.
To answer your question, no it's not.
