Re: Who's eligible to teach Aikido? And what level a sensei should be?
Being in a place where the aikido scene is less mature isn't the end of the world. It may not be as easy to get the highest level of instruction, but even in a country where aikido has been around for a long time, not everybody lives anywhere near a good dojo.
I would at least go and check out the local dojo. If you are lucky, that shodan or nidan teaching in your town is one of the young aikido fanatics that are out there travelling to every seminar they can and going the extra mile to make contact with some impressive aikidoka. That kind of sensei could be very motivating, even if his personal level is not that great yet. Sometimes, when things are a little harder and you have to really work at them, you get more out of it.
I guess I'm saying, don't give up before you've even tried.
