You might also want to look into Wado Ryu. As the founder of the style was also a licensed teacher of Shindō Yōshin-ryū Jujutsu, I believe they tend to be much more circular than most Karate styles. Furthermore Wado can also be translated as the way of harmony.
I second Wado Ryu also as it's more circular than any other style of karate. One of the member here by the user name of Ken Zen Ichii teaches Wado Ryu in Nasu Shiobara City, Japan. Maybe you want to send him a PM if you have any question about Wado Ryu.
