Learning Japanese with Tae Kim was created as a resource for those who want to learn Japanese grammar in a rational, intuitive way that makes sense in Japanese. The explanations are focused on how to make sense of the grammar not from English but from a Japanese point of view.
This guide may not be a practical tool for quickly learning immediately usable phrases such as for travel. However, it will logically create successive building blocks that will result in a solid grammatical foundation. For those of you who have learned Japanese from textbooks, you may see some big differences in how the material is ordered and presented. This is because this guide does not seek to forcibly create artificial ties between English and Japanese by presenting the material in a way that makes sense in English.
Don’t feel discouraged by the vast amount of material that you will need to master. Remember that every new word or grammar learned is one step closer to mastering the language! So get started!
