Excellent!

Ive tried many ways to study Japanese
and Human Japanese has probably
helped me the most. I would still use
other methods if you are trying to really
learn Japanese. But Human Japanese
excels in breaking the language down
for the complete beginner and gets you
to start thinking in Japanese. Which is
vital, as anyone who has tried to directly
translate from Japanese to English will
soon discover. I do not regret the
purchase in the least.
