Is BJJ Similar to Aikido? - At first blush Brazilian Jiu Jitsu techniques and those of Aikido may seem worlds apart. Yet, a closer look finds as many similarities as differences. In fact, the Aikido’s roots trace back to Jiu Jitsu in Japan.

Similarities - The Goal is Control - Many of the submission techniques applied in Brazilian Jiu Jitsu (BJJ) are based on the same principles as Aikido, which are to apply force to tendons, ligaments, or joints in such as to create pain. The while the application within each of the arts is different, the goal of both arts is the same – control of the opponent. The BJJ practitioner achieves a successful outcome through the accumulation of points with throws, superior position, or the ultimate submission of the opponent by “tap out”. In Aikido the joint locks or throws are used to achieve control by bringing the opponent (uke) to the ground and neutralizing the attack

Similarities and Differences Between The Two

Similarities

Takedowns- Hip throws (called "koshi nage") are utilized in both arts. Aikido practitioners tend to favor a simple hip throw, whereas many Jiu Jitsu practitioners use a wide range of Judo throws from the popular "uchi mata" (inner thigh throw) to single and double leg takedowns (popular in wrestling).

Differences:

Focus of the Martial Arts - In Aikido there are no tournaments. Advancement is achieved through a testing process with predefined elements. Jiu Jitsu, like Judo and wrestling, pits one individual against another in a timed match or tournament. Points are accumulated and the ultimate goal is submission often through one of many arm / leg locks or chokes. The opponent signals submission by tapping out.

Conclusion - Despite the many obvious differences in application and training, Aikido and Jiu Jitsu posses similarities from their roots to execution of many techniques. Both are excellent choices for those interested in martial arts and each has virtues that can provide benefit.
