It's a great sport, though not everyone considers it to be a martial art just because you don't punch or kick - but it is, and it's still just as fun. I've been doing Judo for about 7 years and got to a blue belt in the first 3, and a couple of years later passed my level 1 coaching course. I'm not bragging, I'm just trying to demonstrate the fact that it's either one of those sports you enjoy quite quickly and work hard at, or you'll leave in favour of a sport that lets you kick (such as kickboxing).
Nevertheless, I do recommend giving this sport a chance, it is fun if you let it be.
