Can you update your information to include your location? And a photo or two would really help also.
The bad news is that pines grow only on the growth tips. The bare branches are destined to be bare branches forever - they won't leaf out or fill in.
I have seen some really nice looking tanyosho pines with growth only at the top. You can limit growth by breaking out the main candles in the spring and leaving just the side candles. That will make the tree grow slower and also bushier on the top (TOP only).
Look at this one in Osaka, Japan:
