How long do broad leaf Japanese live?

I have a very large 16ft. Japanese maple tree Approx. 20 years old. I noticed today that a very large branch is not blooming, it looks dead? It's a beautiful tree, I'm upset over thought of losing it.

Answers:
most likely prunning that limb will solve your problem.be sure to paint the exsposed area after prunning.see below.
