Sojutsu - The Art Of Spear Fighting

I was just wondering if anyone knows of, or has heard about any schools outside of Japan that train Sojutsu / Yari exclusively ?
Although I was introduced to the spear through CMA. I have come to the conclusion that Chinese spears
a/ suck
b/ break easily
Also, most Chinese spear forms I have seen
b/ are all about show and less about efficiency
b/suck

Is there anyone here who has extensive experience with Japanese spear training ?
