ah-keh-mah-shee-tay
* ah: Like the "a" in "father"
* keh: Like the "keh" in "key"
* mah: Like the "mah" in "father"
* shee: Like the "shee" in "sheep"
* tay: Like the "tay" in "say"
It's important to note that the "e" at the end of "Akemashite" is a very short sound, almost silent.
Let me know if you'd like to hear it spoken out loud!
