Hello Ninjitsu is a good example of a sogo bujitsu style art. Sogo styles tend to focus on a total development rather than individual focus. You learn some grappling, some percussion (karate), some weaponry, and how they interact. From there, you can expand in any way you want. The bonus is that usually they are designed to be learned quickly and efficiently - remember that in war, we don't have years to develop good battle skills. If you are looking for a sampler that's a good place to start. I would be really cautious around Ninjitsu styles, seems to me that there tends to be a lot of inauthentic and/or unqualified people claiming proficiency and teaching in that area (very dangerous). Check out the school, if they don't make sense, you are probably right. For reference, I train at Sei Shin Kan - http://www.seishinkan.com. Hope this helps. Thanks B
