America Akita Fencing - 5 or 6 foot height

Is 5 foot high enough for a chain link fence?

Background:
I'm planning chain link fence to surround roughly half an acre of back yard. I expect to raise this pup as primarily an indoors dog. With my previous GSD/Shiba mix I had to always keep an eye out due to digging. With the American Akita I would do the same -- keep him supervised when running around outdoors. I'm on a corner lot with a few runners and walkers everyday.
