The Samurai’s Tale by Erik C. Haugaard
Levi gives it a thumbs up.
The Ghost in the Tokaido Inn by Hoobler Levi loved this one: two thumbs up! I’m looking at getting the others in the series.
How to be a Samurai Warrior by Fiona Macdonald
This selection is an informative picture book with entertaining illustrations. The boys loved it! 
Peachboy (Rabbit Ears Storybook Collection)
We watch many of the Rabbit Ears Storybook Collection on DVD. Our library carries a huge selection, and I love the narration and non-animated illustrations. It is as if my boys are attending story time at the library.
Chieko and the Pine: A Japanese Folktale In addition to the beautiful Japanese Folktale retelling (illustrated using Japanese sumi-e brush painting), children are treated to a live performance by a Japanese koto player, an interview with a bonsai expert, an example of Japanese traditional dance, and a discussion/demonstration of Japanese sumi-e brush painting (incredible!). 
Countries Around the World: Japan
I’ve said it before, but I am so pleased that our library carries this series of DVDs. We watch one or two almost weekly!
As You Like ItShakespeare set in feudal Japan ~ absolutely GORGEOUS! From our own favorites collection.
