Do you perform misogi to your dojo?
In some dojos, I am delighted to find a series of brooms on a wall or in a corner. They recall me of my first aikido trainings in Tanabe, Japan, back in 1998. There as well, at the end of each aikido lesson, the students would grab a broom and sweep the tatami together, from the outer area to the centre. A very nice way – pure Japanese tradition – to take care of the dojo.
