How could I mess with my name 'Polly' so Japanese can say it?

Question:

i heard that people change it slightly such as William becomes Bill. I can't think of how I can or will it be ok for them to say? Any help would be appreciated thanks x

Answer:

Japan changes the pronunciation of foreign words according to how it can be written in Katakana. There is also no L sound, only the R. If you want your name to be the same, but with a Japanese pronunciation then; Pori (ポリー). The pronunciation is; Po-riiii (elongate the last part a bit).
