I'd have a great deal of difficulty in taking anyone seriously who called their office their "dojo". Or liked their direct reports to call them "master".
I have no problem calling Sensei a particular great coder/architect. I even used to do it for the fun of it.
But when it comes down to management asymmetric relationships, I do my best to avoid biasing it more ("master").
Could be a great way to practice office theater, though.
It's not healthy to consider oneself subordinate to ones manager. You're peers with different roles, that's all. He's more about the what, you're more about the how.
