One of the issues with research into folk arts like our kobudo is that it is actually a pretty involved process. Knowledge of history, language, culture, and so on is necessary not to fall into simple “common sense” mistakes like this. It is cool to have a local and “ancient” origin for the things we do. But cool, or supporting the culture our arts developed in, doesn’t make things true.Sensei Fred Lohse - Kodokan Boston Dojo
