Machiavelli's "The Art of War"

I bought Machiavelli's "The Art of War" in Japanese, as I found it at book store.　I am going to read this starting today.
I like Machiavelli as classic politics. I have read "The Prince" over and over. Although I cannot read original text in Italian, to understand his opinions more I have different three version of "The Prince", which were translated by Ikeda Kiyoshi, Sasaki Takashi, and Kawashima Hideaki. Furthermore, I have also some primers and commentaries.
