Re: Hitohiro saito
He dont teach there anymore his tokyo dojo exepct for seminars. I know it is still there and studenst still practise there and come up to iwama at the weekends.
As for training both, do you mean in iwama? thde answer would be no. If you where uchideshi you would have to decided under H or nemoto. Even sotodeshi you would probably be told to choose 1 way only.
