For what it’s worth: I use Firefox on PC and no issues with the MaruMori site.
I see MPV (video player) Mining Plugin on the roadmap, can this replace migaku? or does it have any current integrations with Migaku? I’m curious about people using both marumori and migaku together in their learning journey
Heya!
Not sure what might be causing the issue for you! I haven’t heard of anyone else with that issue, but there is one thing that turned out to be an issue for someone else before:
In your browser settings you have to make sure hardware acceleration is on, as especially the Adventure pages can be quite taxing otherwise (it plays a lot of videos for the animations).
If that doesn’t help, I think you could try with a different browser and see if that problem persists, if not, its likely either a browser setting or an extension causing issues.
Hey no matter what i try even all extensions removed all settings reset to basic fresh firefox install it still happens as soon as i click the register button my ram fills up and nothing happens on the site
here ram usage keeps growing till 12 gigs active and then it just crashes hardware accel is active

One before clicking the register button and one after clicking it and the usage keeps balooning until hundreds of gb
Hi everyone! A new mobile app update has been submitted to the app stores! As of publishing this changelog, the iOS update has been approved, but the Android version is still awaiting review from Google. Edit: The Android version has also been approved!
As usual, you can get the mobile apps through the following links:
iOS:
Android:
Please note that currently, in order to access the app, you will need a subscription or a lifetime account, as our mobile app is still in early access until we get it on par with the website!
With that out of the way, let’s get to the good stuff!
This update brings the following things:
New Features:
-
The N2 Region has now been implemented in the mobile app as well! This means both areas of the region can be explored, and the two secret easter eggs (not the actual eggs from the easter egg hunt, haha) can be found in the app as well!
-
Suggest Changes - The suggest changes modal has been implemented for Grammar Lessons and Reading Exercises, meaning you can now give us feedback straight from the app! This functionality will also get implemented for SRS items in the near future. You can access it through the red button near the navbar:
Bugfixes:
-
SRS - Grammar - Unscramble - Submitting a created sentence right after removing a token (by tapping on it) would cause it to be marked as incorrect, even if the sentence was correct. This has been fixed!
-
Conjugation Trainer - Fixed an issue where your answer would be marked as incorrect at times, even when correct. This was due to pressing ENTER/submit before “n” gets converted into “ん”. (e.g. with “たべませn”. If you entered “nn”, it would convert before submitting, so it would not cause a problem).
-
Home - Widgets are now properly center-aligned again
-
Study Lits - Study Lists are now properly center-aligned again.
-
SRS - Lessons - Fixed an issue where trailing spaces could lead to your answer being marked as incorrect.
-
Grammar Lessons - Example Sentences - Fixed an issue where furigana over numbers would sometimes overlap with the numbers.
-
SRS - Fixed an issue where you’d sometimes see an empty tooltip pop up.
-
SRS - Grammar - FITB - Fixed an issue where the text would resize after leaving the app and going back to it.
-
Home - Timeline - The timeline now always refreshes properly.
That’s all for now, but expect more mobile app goodness to come very soon!
And if you go straight to https://marumori.io/register from the link in this mesage? Does it do the same?
Perhaps you could try registering through a different browser (or a mobile device) and see if you can login straight through https://marumori.io/login afterwards. Perhaps it’s the landing page that’s causing issues for you. Once logged in it will not load that page again anymore.
Hey clicking the link also causes the same issue. I have however been able to diagnose the issue its caused by a paid Firefox feature called relay. It Allows me to obscure my emails and something about the Maru mori specific registration form caused it to recursively load itself. Everything works now too bad I didn’t figure it out in time for the sale tho ![]()
Thank you for the help.
Glad to hear it was resolved! That does remind me that I’ve heard someone else mention that Firefox Private Relay was causing some issues for them (though that wasn’t for registering, I think).
Considering you wanted to try it out during the sale period, but this problem held you back, feel free to email us at support @ marumori.io, and we can likely work something out if you are still interested when your trial runs out ![]()
@neicul
Would it be possible to make “Continue where you left off in Fledgling Forest” open the popup with the actual lesson and “Start lesson” button? Or even open the lesson itself (no harm in it, each requires confirmation of having it “done” at the end)
EDIT: also one additional thing - would it be possible to add handling [ESC] key to modal dialogues? Clicking outside of them closes them but as I’m more keyboard-guy (and there is a lot of typing either way) it would be easier to dismiss those with the escape key ![]()
N2 Content Drop
Another N2 content drop has hit the rift! Uhh, I mean, the island! More specifically, the Sands of Mastery! And speaking of mastery, how’s everyone’s journey to Japanese mastery going? No one’s doing too many lessons and burning out like a meteor made of kanji, right? There absolutely is not, and was never, a channel referring to burnouts or anything along those lines in our discord server, after all. ![]()
In this week’s batch, we’ve got some fantastic grammatical musings for you. There’s ~とは, which is exceptionally handy for definitions, ~をもとにして, for when we want to say that the novel we’re writing is based on our own lives (a tragedy), and ~にそって, for all sorts of “following” statements (you won’t believe how this one ends!!!).
What’s more, another cultural lesson awaits you, and it’s the absolute winner in terms of tasty content on MaruMori (so far). Let’s just say, if you didn’t know much about traditional Japanese treats, you’re about to know a lot, whether you want to or not.
And as usual, a swathe of amusing unlocks as well await you, not to be outdone by a reading exercise where you can practice reading all of your recent grammar and vocabulary, in context! In this week’s reading, we have an unexpected hanami follow-up, a TV interview, and a peek at the MaruMori Bistro menu, which is very important; we’re working on our own Chef’s Table instalment.
That’s all for now, and always,
Happy studies!
Would it be possible to make “Continue where you left off in Fledgling Forest” open the popup with the actual lesson and “Start lesson” button? Or even open the lesson itself (no harm in it, each requires confirmation of having it “done ” at the end)
The former would be possible I think! The second not so much, as we also have exercise tiles. The lesson modal first explains what the exercise is about, so skipping that would leave out some vital information.
EDIT: also one additional thing - would it be possible to add handling
[ESC]key to modal dialogues? Clicking outside of them closes them but as I’m more keyboard-guy (and there is a lot of typing either way) it would be easier to dismiss those with the escape key
I believe this is already the case with most of the modals at the moment, though I think a few are missing it. If you come across any in particular, feel free to let me know and I’ll put it on my list ![]()
I would very much appreciate the first one <3
The second - that’s a valid point, but maybe this could be moved/repeated in the lesson itself?
That’s easy as I face it a lot: in the review view modals for Meaning (to add synonym) and then Meaning Story/Reading can’t be closed with [esc] ![]()
Website Update! Flip Buttons Mode for SRS, Manual SRS Lessons Picking, Lightning mode modifier, improvements and a whole bunch of bugfixes!
Hey everyone!
We’ve finally had some time to focus on some smaller (but oh so fun) new features, improvements, and bugfixes for the website again!
Let’s get into it!
New Features:
- SRS - Vocabulary & Kanji - You can now toggle on Flip Buttons Mode during the lesson quiz and reviews! This means you get a button for “Show” on the front side of an SRS card, and two new buttons on the back side for “Correct” and “Wrong”.
When this mode is enabled, you have to grade yourself by using the buttons, and the input gets removed, so no typing is involved!
This is mainly handy for when you are on mobile devices, where typing can be much slower and prone to typos, or when you have a huge stack of reviews to go through.
Watch out though! In general, retention rates are higher when you type things out, so use it with care!
- For keyboard users, you can use the following hotkeys while the mode is enabled:
- SPACE - Show
- G - Correct
- H - Wrong
- These hotkeys can also be changed on the settings page (see screenshot below)!
-
SRS - Lightning Mode SHIFT modifier key - If you have lightning mode enabled but want to disable it for the current item, you can now hold SHIFT while pressing ENTER. It will then show the backside of the card, even if the answer is correct (normally, it would skip the backside with lightning mode on).
-
SRS - Mark As Known Hotkey - We’ve added a new hotkey option for marking items as known during SRS sessions. You can go to the settings page to set up the new hotkey.
-
Recently Studied / Leeches - Each table now shows how many items you’ve selected on top of the table.
-
SRS - Lightning Mode now has separate modes for Vocab/Kanji vs Grammar SRS.
-
SRS - Typo allowance has been changed to be a bit stricter.
-
Study Lists - Manage Items - You can now start a new lesson session with items you selected. Meaning you can now pick your own lessons for the day! Super handy when going through any of the parsed native material lists, for example!
Bugfixes:
-
Recently Studied - Fixed an issue where turning the “Mistakes Only” filter on would skip certain items and filter them from the view.
-
Stories - Fixed an issue where certain “elements” used in stories would not render properly during SRS.
-
Grammar Lessons - Exercises - Fixed an issue where the input would not automatically convert from romaji to kana in Firefox browsers.
-
Dictionary - Fixed an issue where certain (counter) Vocabulary would not show the contained Kanji.
-
Adventure - Unlocks Page - Fixed an issue where definitions would sometimes wrongly get cut off, leading to weird definitions for items.
-
Statistics - Your streak now sorts properly before counting, fixing gaps that arose when “fixing” streaks by changing your timezone

-
Grammar SRS - Fixed an issue with furigana sometimes displaying on fake tokens when it shouldn’t, thus giving away the answer.
That’s all for now! But in the background we’re working on a few exciting things, so keep an eye out for more updates soon! 
Question. I’m a bit curious about this platform, but I find it a bit too expensive (I don’t really like subscriptions, so I’m really looking at lifetime here). So far I’m very happy with wanikani. So much that even if I was not totally convinced about bunpro after the demo I still paid for the lifetime subscription, just to give it another chance, see if it works. Right now I’d say I don’t really think SRSing grammar is a good idea. So the thing is, what do you offer for practicing grammar besides SRS? I’m also taking in person classes, and we usually do exercises from Minna no Nihongo which I find useful, and something I’ve yet to find on any learning website is a good selection of exercises. I mean, I can buy a textbook and do them by hand, but I’m already doing that in class, and also, who would correct them? So I don’t know why there are no websites with varied grammar exercises.
For Grammar SRS, we offer two different review styles. The one which you are used to from Bunpro would likely be Fill in the blank / cloze style. But the other style we use is called “unscramble”, which has you create sentences from vocabulary/grammar blocks. Your sentence then gets marked as correct or wrong. Here’s a random example of what that looks like:
In MM you can force Grammar SRS reviews to always be in this style from the settings page. Perhaps this suits you better?
As for non-SRS grammar practice tools:
We have something called the conjugation trainer, where you can train most conjugations (or a combination of conjugations):
We also have a verb transitivity trainer, where we train you on transitive versus intransitive verbs, and when to use them:
Aside from that, we have JLPT mock exams, which check your knowledge using the exact same question types used on the real exams. Anything you do wrong will link you back to the corresponding Grammar Lesson / Vocabulary / Kanji that you can then (re-)study to fill in your gaps of knowledge:
But our main thing (aside from study tools, mini-games, grammar SRS, and learning kanji/vocab similar to WK) is our Grammar Lesson content. We currently go from absolute beginner (Pre-N5) all the way up to N2 (currently being released in batches). So essentially, you also get a number of textbooks included in the same price. I’d also like to note that feedback to our teaching style in the grammar lessons has been tremendously positive, making grammar click for a lot of users.
In that regard, I think the price is more than fair, but I’m very biased, of course ^^ I’d encourage you to try the 14-day free trial and explore some of the above mentioned features and then decide whether you think it’s worth it or not. If you deem the price too high, we hold sales once in a while too!
Thanks for all the info! I want to test the free trial, but it needs to be in a moment when I know I will have enough time, which is probably in 2 weeks. I will tell you my use case and my opinion from what you tell me, and you can take this as user feedback if you please. Please don’t take anything I say as bashing or whatever, I will try your tool and provide further feedback if you find it useful.
Basically for now I’m going to in-person classes. The teacher also streams the classes, so I think that would cover a large part of my learning even if I went to live somewhere else. These classes are grammar heavy, and specially I found we are very slow at learning kanji, so I’m finding Wanikani very valuable. Free resources cannot compare. I took a look at KanjiDamage and the mnemonics are pretty bad, plus not having to planify anything on your own is a plus if you don’t have a lot of free time.
So basically I have been looking all over the internet for extra practicing of grammar, and maybe advance faster on my own if possible. But I don’t see websites with high quality exercises that improve output.
Now, from what you’ve shown me, and maybe after trying I may change my mind. I found Bunpro style exercises to be a bit poor. The ordering ones I think are something like Duoliguo style, which I haven’t found useful either. Tools pretty similar to the conjugation trainer can be found for free on the net, as well as grammar lessons (imabi, tae kim, even bunpro lessons are free to access). Now something like JLPT style exams with correction can be a nice tool, I may like that. I also think something like Minna no Nihongo style exercises, with the LLMs that exist nowadays to correct them could be cool.
I would find cool that you enter on the platform and it does everything for you, it tells you this is the lesson for today, and these are the exercises for today. But exercises that require more output from the user. Building complete sentences describing what is on an image: left of the desk there is a cat, or exercises to follow x grammar pattern with an example first sentence, etc. This way you’d be practicing everything together (grammar and vocabulary output). Usually on a text book on a unit you will receive an amount of vocabulary, an amount of grammar together and you work on it. For example, unit of hobbies, you learn a bunch of related vocabulary, how to say your hobbies, how to use adjectives, etc. First the lesson, then the exercises (listening, writing exercises, with more or less freedom to input) to interiorize it, and with time maybe once in a while a refresher exercise, but mainly exercises should build on the previous knowlege, I find preposterous to study grammar separately, like if they were isolated “points”. You could say I’m a bit alergic to hearing SRS and grammar on the same sentence
. I mean the whole integrated course is the ideal, but I’d settle for just textbook quality exercises that the website corrects for you. I think websites usually don’t do this, because each different type of exercise is something that needs to be implemented. If it is too open, then it is more difficult to correct, and these type of basic exercises are just cheaper to create. But in the end, in my humble opinion I don’t think they are an efficient use of the user’s time.
Sure, but those sources are all very different in terms of where they can take you (e.g. Tae Kim only goes up to a certain beginner-ish level) and especially very different in how they teach you. Imabi, for example is very “dry” (but awesome nonetheless), a completely different style from how we teach.
This is pretty much what our main “Adventure” course is. Every day, you complete a tile along a path until you finish a region (although you can skip to whatever you want, whenever you want too). It’s a mix of grammar lessons, reading exercises, course exercises (like conjugation training, after learning a new conjugation type), and unlocks (vocab & kanji).
After reading through a grammar lesson you get the corresponding grammar points in your grammar SRS lesson queue. So you are not studying the grammar points in isolation, you first have a dedicated textbook-style lesson for it.
Our sentence-based “unscramble” grammar SRS is the closest thing to what you’d want, other than having a private tutor correct your sentences. It’s nearly impossible to account for all possible sentence constructs when you get into more advanced territory, if we were to allow completely free input from the user, hence why we limit you to using blocks to create the sentence.
That said, our grammar SRS sentences can get very complex, especially in the latter regions (N3+), and we do our best to accept alternative combinations as well. So it’s not like you’d only come across simple sentences ![]()
Our Grammar SRS also builds upon previously learned knowledge. Meaning no unknown vocab, kanji, or grammar in those sentences. Only what you’ve previously learned (as long as you keep up with the unlocks and make sure to follow the path).
In any case, if you end up giving MM a try, I hope you enjoy it! Constructive feedback is always welcome ![]()
Sure thanks a lot! I will surely try it. I think with LLMs are something that will help with the issue you mention. For me it is important doing output without doing translation. This is something that Minna no Nihongo does very well by using images or a couple of words as input for you to build a sentence by yourself, but it is also true that I’m still on a basic level, not sure how an LLM handles more advanced japanese…
LLMs are prone to mistakes and will often hallucinate/agree with something you ask of them. Not exactly the best way to learn if you can’t be certain it is 100% correct. If it teaches you a wrong pattern or makes things up, it can be very detrimental to your learning, as it can make you form bad habits that would be hard to get rid of at some point. So I would personally caution against it until it drastically improves ![]()
