4.8 out of 5
Ad loop

Every time i try to select the “conjugation” section on the home page i have to watch an ad, which ok fine. But then when the ad is over, I get sent back to the home page. I try to click the same section and the above repeats. I cant access this part of JapaneseGrammar at all and its not a premium feature!

A lot of recordings are missing?

JapaneseGrammar could be really amazing, but a lot of the recorded words/sentences etc. don’t always play. I think this could be a super useful tool (and I’ve paid for premium) so please fix this ASAP! Hard vocabulary mode also only gives one question before saying the entire quiz is completed?

Great concept, needs work

JapaneseGrammar has functions in it I've been looking for! The execution, however, is only so so. Crashes, doesn't save data, audio checks don't work, isn't tablet compatible. I would absolutely pay for an app like this that had more material and fewer bugs.

It’s nice but...

I don’t know why I cant do the drag and drop off the exercises, it won’t drag anything and it won’t show the meanings either. How do I fix this? Other than this, the explanations are pretty nice and I like them so far! So I would recommend JapaneseGrammar even if it’s only for the actual lessons not the practices (as I said mine won’t work).

Almost great with glaring problems

While JapaneseGrammar does appear to be one of the best sources for learning the grammar of N5 specifically, and I plan on using it for that, I think it has tons of issues that hopefully can be hammered out with future updates. There are tons of performance issues/glitches when navigating the menus particularly when exiting a lesson. I think vocabulary could be made all around better for learning by not making it multiple choice, or at least having the option to do that. Also it seems reviewing vocabulary is likely a huge pain since you have to manually add words to create your own review list, and without doing that you don’t really have any options. For grammar stuff it’s hands down the best resource I’ve found, but again, the UI doesn’t work well. I hope these issues can be fixed at some point, especially the UI problems because that’s just really bad.

Not bad but some issues

JapaneseGrammar isn’t bad however there are some issues. The translations are a bit wonky and some of the quizzes do not specify which vocabulary words they’re looking for especially for the vocabulary words that have similar meanings. Also, JapaneseGrammar freezes after some time of use. I can only go through one lesson before JapaneseGrammar freezes and I have to wait to close it and restart. The customer service has been nice so if you do have some issues, there shouldn’t be any problems reaching out and getting it solved. Overall, JapaneseGrammar has potential with some cons.

Look no further, this app is it.

Coban is excellent for learning Japanese. From complete beginners to advanced, it has everything you need. The layout, functionality and depth of learning material is impressive. I especially find the explanations of grammar with examples and exercises to go with it useful and engaging. The developer actively updates JapaneseGrammar and responds quickly to user inquiries/suggestions. Highly recommend, JapaneseGrammar is one of the best.

Super Useful

I've been using JapaneseGrammar to learn Japanese for only a few months, and I've definitely have been progressing since then. However I find it a bit difficult to remember things, but I've been doing other things to remember the characters and words, like watching videos in Japanese. It's super useful and I definitely would recommend it to anyone who's interested in learning Japanese.

Great resource for beginner

JapaneseGrammar offers both free and subscription options for the user. For me, without the subscription, I still get a good amount of resources for reviewing the alphabets and grammar. The subscription will offer more for the learner to practice their vocabulary in reading and listening. In addition, to the resource, the interface is nice and easy to navigate. I would definitely recommend JapaneseGrammar.

Great app!

This is my favorite app for learning and practicing Japanese. I struggle with particles and sentence structure so I love the drag and drop feature on here. It also covers everything you need to know, I hope they expand to offer all JLPT sections. Some book explanations can be confusing but this is very simple and straight forward. It was recommended to me by a friend, glad I downloaded it! Keep up the great work.

COBAN— For Learning Japanese

I am really having fun learning Japanese with JapaneseGrammar. I also like being quizzed afterwards. I have other JAPANESE APPS but this one ☝️ is the only one that I take the time after studying that I test myself. Like I said before it’s fun. When it’s fun 🤩 you explore the whole APP to find out everything it offers to help you. THIS IS JUST MY OPINION. If you are learning Japanese just explore JapaneseGrammar.

Amazing start looking forward to updates

Anyone around JlptN5 level and learning N4 kanji should get JapaneseGrammar, basically absolute beginners. I wish I found JapaneseGrammar earlier, so now I’m just waiting for it to update with N4 grammar breakdowns, and N3 hopefully. Other than that very pretty app, but I do have some suggestions. First of, it isn’t working completely fluidly and does get finicky with drag and drop, and occasionally freezes stutters—I am using iPhone 12 for reference. Anyway aside from that, I think for new learners, it’s good to have an immediate learn/review button. Learn the term, and practice immediately—although I don’t mind the way it’s laid out now. Anyway great app really looking forward to an N3 update, and to really use it 🙆‍♂️ great great start.

Perfect App for Beginners

Trust me, JapaneseGrammar is amazing if you don’t know anything about Japanese, this will teach you katakana and hiragana and introduce you to kanji, basic grammar and vocabulary for FREE! Something that is also amazing is that that don’t have too many annoying adds. Thank you so much for making JapaneseGrammar 💕

PS: They also have an amazing website with a lot of free content, please check it out

Love it!!!

JapaneseGrammar is awesome! It’s really helped me solidify my kanji knowledge and I’ve been using it a ton since downloading it. I only have one request: Could you please add the N3 kanji as well? It would be great if there was an N3 kanji section, one that’s just like the N4 kanji section, with the same format, same reading/meaning sections and everything but for N3 instead. That would be super helpful.

Very helpful!

I originally had some issues with button interactivity, but after re-downloading JapaneseGrammar I have had no problems since! The listening part of JapaneseGrammar is very helpful, I think, and not something I see in other Japanese language apps. Great work guys!

I would rate higher

I would rate higher, honestly it’s a super underrated app but the only thing that bothers me are the occasional bugs now and then like kicking you out and for a new language learner, personally the fact that the ranks don’t load sometimes is a little upsetting.

very helpful!

I wish I had discovered JapaneseGrammar earlier when I started Japanese. JapaneseGrammar has drastically improved my knowledge of the basics and I hope for more updates in the future.

An App you will not regret downloading

Whoever made JapaneseGrammar is nothing short of a saint, considering the fact that it actually makes an effort in teaching you most of the generic Nihongo terms, grammar, kana, and Kanji that wannabe casual Japanese speakers will want to be able to identify in an everyday setting. I legitimately have no idea why in the world no one else didn't even bother to review this, so take my word for it; it's a great app for people willing to put in the work to study the language!

Palatable grammar for short attention spans

If you got a goldfish attention span like me, JapaneseGrammar is pretty good in getting the basics of grammar. After struggling to go through the genki textbook and tae Kim’s grammar, I just decided that an app is easier for learning as an absolute beginner.

Now I’m not necessarily saying that an app can replace stuff like tae Kim or genki, but at the very least I can punch out some grammar per day and try to retain bite size info.

Disappointed that this is a subscription model. There isn’t really enough updates to justify the lack of a “lifetime” purchase. However I still think it’s a solid app and you don’t have to pay anything if you don’t want to.

Crashes after update

I just want to start with I LOVE JapaneseGrammar, it’s well organized, easy to navigate, and fun! However, ever since it got updated whenever I finish a set of exercises it crashes. And the progress from completing the exercise doesn’t get saved. Again, I still love JapaneseGrammar. I 100% recommend it, crashing and all.
