"Traditional" language education general involves memorizing numerous artificial grammar rules by wrote. This generally leads to very little long term acquisition of the language, and no natural feel for the language.
In contrast, this app allows users to truly acquire Japanese by allowing users to see it regularly in context. This allows users to see really how the vocab and grammar is actually used, instead of trying to puzzle out complex descriptions with exceptions generally listed in textbooks. The stories are kept entertaining with general silliness, but that only adds to the long term retention of the Japanese used. ENJOY!
