A short list of phonetic (that is to say, probably misspelled) phrases I’ve gleaned from a watching a week’s worth of Japanese horror movies:
Konichiwa: Hello (formal greeting).
Domo: Hello (informal greeting).
Moshi moshi: Hello (telephone greeting).
Arigato: Thank you.
Nonni: What is it?
Aaaaaaiiiiiiaaaaahhhhhhhhhhh!: I appear to be under attack by some kind of creepy kabuki ghost emerging from the shadows, could someone please notify my next of kin?
