Kate, as in the name, is ケイット, pronounced "keitto"
There is no "correct" way to write foreign names in Japanese, you spell it how it sounds but a couple of good ones are:
Keiti - ケイティ
Kati - カティ
Katherine is "kyasarin"in Japanese
ケイト = Kate
You may write it as: ケイト
it means "kate" , the girls' name
No, you will need to write a letter in the mail to Clarence House if you want to write to Kate.
