Here you can download the online book as an eBook, 3D models of weapons and tools, and a ninja font.
Iga Ninja Font
Many years ago, the Iga Ninja Museum published an image of an Iga Ninja cipher on their website. I developed a font from it, which can be downloaded here.
3D Models of Ninja Weapons and Tools
For the first version of this website I created 3D models of weapons and tools, which I later converted to stl format. The models can be viewed directly in the browser on GitHub and viewed from all sides.
