This audio book attempts to teach you basic Japanese by following a kooky story in which you are recruited as a spy to find out why a group of wannabe fans who love a show similar to Power Rangers has taken over a Japanese theme park. Interspersed with the story are lessons that teach you basic Japanese. It is a fun book to listen to, but it does go very fast through the Japanese. You may have to repeat parts often in order to learn the Japanese. Otherwise, this is a novel idea that is very enjoyable. If you like it, the author also has an audiobook about learning basic Mandarin Chinese as well.
This was not a well put together learning program. It consists of a narrator saying a never ending list of new words. There is no opportunity for the listener to repeat the words or any conversational learning. There are far better options available that "teach" vs just shoot words at the listener. I highly recommend going with a different book/program to learn Japanese.
