Fun for what it is.
It's been a reasonably good brush up for me having not studied Japanese for close to a decade. They've done a good job balancing the entertainment and educational factors — certainly a difficult ask. Recommended as an extra learning tool but nothing beats the real thing!

Cool!
When this product arrived I was not to thrilled to be honest, but I tried it out and... I AM A BELIEVER!!!
It is really fun and I learn a bit Japanese at the same time!

This is a must buy folks!

Great resource to learn Japanese! I had more fun learning Jap thru this game then when I attended lessons! A sure pick-up if you wanna start learning Jap...

Great practice material
I really like games in this software which can help you to remember how to read and write. It helps me a lot in master the Kana.
This software also focus on the grammar. It lists the grammar points in the lessons step by step. I find it quite helpful for the Japanese beginner like me.

Good for beginners
...but rather tedious if you have prior knowledge. I had been studying the language for nearly 3 years when I picked up this game to practice before studying abroad. Unfortunately, while I aced the "placement test" at the beginning it still forced me to spend quite a bit of time "learning" the words that I'd known since my first semesterof study. It also continues using romaji for what I considered to be a rather ridiculous amount of time (given that it extends far past the end of the kana lessons) and doesn't begin teaching kanji until about 40 lessons in. Admittedly several of the minigames (fill in the blank and scrolls specifically) are very useful for remembering the readings of kanji and the words learned in the lesson, but it takes quite a while to unlock them, and I found a lot of the early games quite useless.

A word of warning: several of the hiragana are written in unusual ways in the game, specifically sa, and ki--expect to be marked down by the program if you do not attach the bottom stroke as in printed characters vs. handwritten ones.

Despite this it gives very clear explanations and has a handy feature where you can record yourself saying the vocabulary words then compare it to a native speaker's pronunciation. It would be a very useful program if not for the lack of means to bypass unnecessary lessons.
