The Takate Kote or Box Tie is one of the most widely used ties in Japanese Shibari positions.  Here is a very good video tutorial by deGiotto, a Houston based rigger, educator, player, shibari materials supplier, and generally nice guy.   He demonstrates this tie with his long time model/bottom, elise.

There is a video tutorial after the jump.

As deGiotto correctly points out in his video, this tie can be dangerous.  He and I both recommend you get in person instruction from someone who is experienced with this tie.  But. this video tutorial will help you understand the basics of the tie.

You can see more of deGiotto tutorials on his youtube channel here.

Be careful and Enjoy.
