Hello,
For those of you interested on a good website resource for Medieval Japan, I recommend the following PBS website focusing on Medieval Japan (link below). This website was made in connection with a video PBS created by the same name (Japan: Memoirs of a Secret Empire). The website provides resources, timelines as well as a neat section where you are able to choose a character either in Edo or Tokaido and learn about them (ie. samurai, ronin, geisha, daimyo, artisans, monks, etc..). All in all, it is bring good & could lend to some assistance in helping students understand this era a bit more.
