Copyright statement

This site describes techniques for self defense. In theory there is no copyright on self defense techniques, because these technique are from 'nobody', and could have been made up by 'anybody'. If the people of old in Japan would have known the concept of copyright, it would be impossible for us today to execute budo, because all techniques have been used and/or described.

That why we cannot and will not copyright the techniques on this site. On the other hand, it took us a (very) long time and trouble in creating this site (for example, we filmed at least for 500 minutes, edited these in 5 weeks and translated the site in 2 months). In order to ensure that this time and trouble has not been for nothing, and the authors of this site can keep track of where the films can be found, nothing of this site may be reproduced without prior consent of the users.

Thus, the use of the techniques itself are free (under the disclaimer), but the 'use' (i.e. copy or publishing) of the film and descriptions of the techniques as given and used on this site may not be used without prior permission.

In setting up this site, the authors also, of course, used various sources about budo (jiu jitsu, judo, aikido, etc.). These are mentioned in the 'Sources' part, to ensure 'credit where credit is due', and to ensure that the 'originator' of a technique is mentioned (noting the above made statment about that no one is the real 'originator' of a certain technique). .

The authors wish to thank anybody who helped us making this site, directly or indirectly (i.e. via books, etc).

Here a more formal version of the above (where this text is in contradiction with anything mentioned above, this text should be used):
