The below list is a comprehensive list of many of the more useful or popular webpages that have to do with Nihonto.
I have not yet listed all of the excellent websites that are purely in Japanese. A listing does not necessarily indicate any recommendation of the services or information contained therein.
Note that many of the commercial sites have excellent informational reference sections, and it pays to browse the site a bit. If you have any suggestions on new links to be added, please contact me, Brian
Robinson and I will add them on the next update. Please notify me of any dead or incorrect links so that I can update or remove them.
