Hi, 必殺技 is ひっさつわざ or hissatsuwaza (not hisatsu.) Japanese has long consonants, which are represented by a small "tsu." It is not pronounced "tsu" when it is small, it stands for a lengthening of the previous consonant. Good luck with your studies of Japanese. Thanks

a/an
PS, in English, "an" is used before words that start with a vowel or vowel sound, so we say and write "an ultimate," not "a ultimate."
