About the free online course

Want to understand beginner Japanese grammar without guessing or memorizing random rules? This free online course helps you build a clear JLPT N5 foundation using the grammar taught in Genki 1, explained in a way that connects the dots between forms, meaning, and real usage.

You will learn how to create accurate polite questions, choose the right particles in common sentences, and confidently form essential verb patterns. By practicing the ます form, casual short forms, negatives, past negatives, and the て-form, you will start recognizing how Japanese sentences are actually built and why small changes completely shift the meaning.

The course also supports everyday communication skills: making polite requests, inviting someone to do something, expressing what you want to do, describing actions in progress, and comparing things naturally. These are exactly the building blocks that make beginner conversations and reading feel less intimidating.

Each lesson includes quick exercises that check understanding right away, so you can spot mistakes early and fix them before they become habits. Instead of overwhelming you with long theory, the course focuses on clarity and repetition through practical examples—ideal if you are self-studying, returning to Japanese after a break, or preparing for the JLPT N5 with a stronger grammar base.

By the end, you should be able to follow common Genki-style sentences with far more confidence, form your own beginner-level statements and questions, and approach new grammar with a method that actually makes it stick.
