Re: Where does "Morote Dori" come from?
Seems obvious to me that it would be common to do so throughout the ages, too obvious. Firstly when someone has a sword or weapon, especially a large weapon many would use two hand grab of arm.
Secondly and even more obvious is don't get so caught up in "it has to be written" over common sense. What do you think Ikkyo is other than a morote dori in essence.
