When it comes to language learning, grammar might seem like a kind of super weapon.

Well, let me tell you a secret: It actually is.

I have gathered 10 great resources to help you learn grammar online using Japanese grammar exercises, from the comfort of your own home. 


1. Maruguto Plus

Best for: Beginners

Marugoto Plus

Marugoto Plus is a site compatible with the contents of “MARUGOTO: Japanese Language and Culture,” the official course book of the Japan Foundation. Having the textbook is not a prerequisite in order to use the site, and all of the site’s content is super useful.

What’s interesting about Marugoto is that its culture references are not strictly Japanese; you can learn about other cultures as well! Marugoto Plus is great for studying the grammar for A1-A2 levels of the JF Standard through an array of conversations, videos and pictures. The A1 level is available in Japanese, English and Spanish while the A2 level is available in Japanese and English.

2. Visualizing Japanese Grammar

Best for: Beginners

Visualizing Japanese Grammar

Visualizing Japanese Grammar is one of my favorite grammar sites for beginners. It contains 66 flash animations, each presenting a different sentence structure. Every unit consists of a flash animation, complete with explanations and examples, a vocabulary list and a final quiz to test your understanding of the lesson.

The explanations are presented in both Japanese and English, and at the end of each lesson you will see a list of other related units. There is also a side menu of all available units, so you can choose the grammar structure you want to learn in particular.

The site, on top of the video lessons, offers 12 PowerPoint presentations with all the key elementary grammar points. It is a great place to start if you’re new to learning Japanese grammar, and it’ll make your life easier when you turn the page from the elementary to the intermediate level.

They all do have a special meaning.

The exercises allow you to turn your keyboard to Japanese input and get a real feel for the way Japanese is written. The site follows the grammar sections of the textbook and contains various exercises—from choosing the correct masu-form (-ます) to those difficult past tense adjective conjugations.

At the end of each practice session there is a very useful summary to review your answers and find your weak points. It’s a great site for brushing up those important basic grammar points.

It supports more than five languages including English, Japanese, Spanish, Korean and French. It has 25 lessons with videos of real-life situations in which you can hear a near-natural form of the language.

Each lesson is divided into seven parts:

  • The Basic Skit contains a situational video, which has the ability to turn into a manga!
  • The Advanced Skit contains language as you would find it in a normal conversation between Japanese people.
  • You can study the lesson’s key expressions in Key Phrases.
  • In What Is This? you answer questions relating to the topic of the lesson.
  • Let’s See is a section where you have to answer questions based on pictures relating to Japanese culture.

  • And finally, in Develop Vocabulary you can practice the words related to each lesson’s situation or topic with the help of pictures.

The site also offers a mini-game where you have to find your way through a small Japanese town. All the dialogues are solely in Japanese, making the game a great practice on reading and general understanding.

The site covers all levels, from elementary to advanced grammar. You can practice each of the lessons with quizzes and flashcards.

10. FluentU

Best for: All levels


FluentU doesn’t exclusively teach grammar, but it’s an excellent way to learn grammar concepts in action.

FluentU is a language learning website and app that uses authentic videos to teach Japanese. Each clip is equipped with expert-vetted subtitles that are interactive—with one click, you can see the meaning and example sentences of any unknown word and add it to a custom flashcard deck. If you’re learning at a verb, you’ll see which form it is conjugated in. It also features personalized quizzes to help you understand everything you are learning.

The more native content you watch, the more familiar you will become with common grammar concepts found in real Japanese.


So, there you have it. These websites are sure to fill all your grammar needs, whether you’re a beginner or an advanced learner.

Grammar is really important when it comes to successfully translating your thoughts to speech. There is a whole unconscious process in the works, from thinking what you want to say in your native language, finding the right words in Japanese and then trying to make a comprehensible sentence out of them.

So don’t just attempt, learn how to do it properly—with grammar. What are you waiting for? Go out there, check out these sites and find your favorite today!
