Star Wars English-Japanese Dictionary for Padawan learners
And why not? While I recently experienced a plethora of Harry Potter goods that offered a more immersive experience for the dedicated fan, there is no escaping the grasp of all things Star Wars. If you can look at it, hold it or use it in some way (including during those furtive, individualized acts of bodily pleasure), there's probably a Star Wars version of it.

I'm not going to give you any examples of Yoda speak.
Yes, many people in Japan also enjoy Star Wars. There's already a Darth Vader language book for those who want to speak like a Sith Lord and now here's what I take to be a more generalized Star Wars quote translation book.
