The One Deck — 83 Comments

  1. Great stuff. I’ll likely buy the whole package once I’ve reached the point of J-J branching. This page rocks too much to avoid buying something or contributing to it in some way.

  2. The deck is huge, while the order & difficulty of cards is haphazard (considering It’s 9000+ cards of custom-made branching).

    Speaking for myself, this deck is worth buying. TheOneDeck was made during Adshap’s 5+ year Japanese adventure, all in monolingual format. A deck of this quality can’t be found anywhere but here.

    (Of course, it can be recreated, but it would take a few months or years).

    9859 cards may be impractical for some , but imo it is something that most people could take advantage of.

    Side note: I reordered the deck by i+1—optimized for bottom-up instead of top-down processing.

    Side note: I never intended to branch J-J cards. I stop after one monolingual definition and translate the definition to English. The branch annihilator still provided a few useful tips for mining and making cards.

    • A week later….

      After going through the deck a bit and reading through the guide, I was determined to start branching. Progress is evident.

      It was pretty difficult the first few sets of branches, tho.

      • After seven weeks…

        I’ve gotten used to branching. My Custom/OneDeck card ratio is around 1:1

        I mine from both TheOne and external sources

        • Any idea how many J-J cards you are at? Adshap mentioned somewhere that the turning point for him was somewhere at the 700-1000 range, which also matches my experience.

      • One way to do it is to install the MorphMan plugin. It will use your mature cards to reorder your new cards into i+n order. Once it can no longer do i+1 it automatically starts doing i+2, etc …

  3. This is amazing, and I’m definitely grabbing the full package next paycheck.

    That said, I’m concerned that my grammar is shaky, and my girlfriend wants to start on her own Japanese journey.

    Do you intend to make your J-E deck available for download in the future?

    • Unfortunately when I started with J-E, there was no Anki. However I’ve been in the process of working on creating a J-E deck for Jalup which should be good to start and lead into the J-J deck. No time estimate just yet, as it is really the process of creating an original textbook (in Anki form)

      • Oh! I completely understand.

        I went through the “J-E” stage pre-Anki as well, but I do most of my review work in Anki now. The entire reason I hadn’t just crafted a J-E deck of my own is mainly the time investment — my top speed for J-J is 60 cards/hour, and I’d rather throw the over 16 hours of making a J-E deck into expanding my J-J deck if possible.

        Thanks for the quick response. Can’t wait to dig into The One Deck!

  4. Is there any chance you could just post a few examples of some (of at least what you consider to be) more difficult entries so that I can judge its usefulness? I’d rather not buy it, browse the cards for a bit, and eventually have to try to get the refund.

    • Are you worried that the cards will be too easy for you? There is just so much variation within the deck that whatever I show wouldn’t exactly provide any kind of indicator of what the deck is generally like. There are cards that range from simple to average to difficult to super complex.

      • I can understand that with almost 10k cards. How about just divulging 10 random-ish cards out of that whole deck (0.1%) instead?

        I admit I may have missed some posts where you’ve done this already, but I think that this sort of information should be on the product page itself. I have issues buying things sight-unseen (I don’t think that’s just me).

  5. I’m not able to see the images. Are they included or can they be posted as a separate file?
    Thank you in advance and a huge thank you for making the deck available!! I will post a comment when a month has passed.

    金木犀 a fragrant olive(?) ( ̄O ̄;) (笑)

    • The images in the deck (there are probably around 50-100 total) are currently not included. In the old days of Anki, images weren’t exactly the easiest to use, and they didn’t transfer well. I will see if I can find out where exactly they went (they are probably on an older computer somewhere). If I can’t find them (or they are gone), at least they show where I used an image.

      I remember especially using them for Japanese names, in which I chose a celebrity with that name, and then used their images.

      The sentence with 金木犀 was actually from the J-drama Nobuta wo Produce. For some reason I never forgot the sentence or even the source it came from!

      Good luck with the deck and definitely post back later how it goes.

      • Ah I see, thanks for the speedy reply! If it turns out to be too much of a hassle to retrieve them just let it be, I’ll survive without them.

        So far (23 days, 238 cards) the deck fits like a glove, that is to say I’m struggling but at a manageable level. I’ve only hit one card without *anything* new. :)

        I’ll be back!

        • Glad to see you are still going strong and the deck and branching are working out well for you. Since the last video contest its been a while since you posted here! I guarantee you will continually find new material in almost every card.

          And as soon as I get access to my old pc (which isn’t where I live) I’ll scan the harddrive to see if these elusive pics still remain.

          • Thank you Adshap!
            A month has passed and so far, so good! I think the deck is great; new words, fun stuff and I like the Japanese descriptions.
            According to the level test I’m at level 35 and I’m going at 10 new cards a day. I haven’t followed the site in a while so I’m not familiar with the current branching strategies. I have been in the J-J phase for quite a while and have branched sentences myself though.

            Is there any recommendation on all the non-RTK1-kanji in The One Deck? Because there is a lot of them. Right now I’m sort of ignoring them and try to learn the kana reading instead.

            • If you come across kanji that wasn’t found in RTK1 (which will be a lot), just learn how they are read in the sentence. That’s all you need. There is no need to create separate kanji cards for new kanji outside of RTK1.

      And just for those whose Japanese level isn’t that high enough but are wondering the same thing, コリーロングマイヤ asked whether it was possible to merge his Anki deck with my Anki deck. The answer is yes, and it is a fairly simple process. The link above provides guidance, and if for some reason you need further details, there are a number of forum posts on “how to merge 2 anki decks together.”

  7. The One Deck + The Branch Annihilator + XPNAVI: $41.49

    i will be buying this within a week, but I wanted to know what is the XPNAVI anyway?

    • The deck does not have sound files.

      I don’t really feel though at the J-J stage that sentences with audio are really that much of a benefit to make their creation worthwhile.

  8. Would this be recommended for someone around level 20?
    Finished Heisig and currently i’m studying the core 6000 on Iknow, but the app is impractical on the move. I’m around 1300 words/sentences now and study every day =)

      • Thanks, Bought the intermediate package yesterday ^^ So is it intended that I branch through the one deck as in picking sentences out or should I just start the deck and look up the words that I don’t know yet. Everything looks great so far =)

        • Kind of a combination of the two. Start from the beginning and work your way forward. Suspend or delete cards that are way over your level, and branch cards that have low to intermediate difficulty.

          If you use the suspend feature, you can always come back to the more difficult cards later.


          • I also bought it last week but regrettably I haven’t completed RTK prior. I had started several times but I guess I’m one of the few who just couldn’t get into it deep enough to finish. Am I the only one?

            On the other hand, I’m currently working my way through Wanikani, in which I find I’m much more engaged for the long haul. I’m still in early stages of WK (level 10 of 50) but I have more than 1000 J-E sentences under my belt. I’m around level 24 in JALUP’s scoring (maybe due to my kanji handicap?) Anywho, I find myself very sloooow at the ONEDeck and repeatedly looking up words. I’m definitely learning and excited but don’t want to get discouraged either. Adshap, any advice? Or anyone else at the same level as me and can offer their experience/tips?

            I’m super psyched I found this website as it has given me newfound confidence where I felt hopeless! Thanks everyone!

            • Thanks for responding so quickly. That’s definitely what I’ve been doing so far (without the realization that I was actually doing the J-E-J phase). I’ll try to be patient with myself and keep chugging along.

    • Depends what pace you go at. If you did 15 new sentences a day, about 2 months. Another month if you do the J-E-J bridge at the same pace.

    • Some of the cards from the old Jalup 1000 + 2000 may be slightly easier than the latter cards since they were added first. But since branching is a very mixed up experience where you don’t really know where you end up, this trend doesn’t hold through with the whole deck.

    • I have to agree completely. With the new addition I’ve actually come across multiple cards that I already know, easier definitions of words and overall less complex sentences.
      Although it would have helped to have these a year ago it’s pretty cool to notice the progress that has been made since one started the deck. The new cards also help with cementing and clarifying definitions that were a bit vague in my mind.
      The sweet One Deck just got a bit sweeter! :D

  9. I have this now, but I’m wondering, after I go through the Beginner 1000 + Intermediate 1000 completely, should I just go through the entire deck or just mine from it? I know getting sentences of my own is more beneficial in many ways because you connect more, however, it’s all there to get me to fluency and usually any sentence, as long as it’s helping, won’t bore me. What do you think Adshap?

    • You can try both. You can first attempt just go straight through it, and if you aren’t feeling the results you can just mine what you want from it. Many people have used it in different ways.

  10. ” I just finally found these lost picture files, so if you have already purchased this deck and feel they would be helpful to you, please download them here, and add them to your Japanese media folder.”

    Is the folder called “”? I don’t think I can find any other media folder.

  11. For the cards with multiple definitions for one sentence, do you recommend to create a new card for each of them with a unique sentence, use them as is, or suspend them and only use the single word cards? Wouldn’t it make reviewing difficult if you need to get 5 things right for one card?
    The JALUP intermediate doesn’t really follow this format, so I’m not sure how to approach it. I don’t mind leaving them as is if you think that it won’t be a problem. I probably won’t be touching them till I finish the JALUP advanced, just want to have myself prepared (or when premade decks stop getting released).

    Was thinking about suspending them, but there’s a lot like that. And with the branching considered, it would make future single definition cards difficult, as they build off the ones prior.

    • This should only appear at the very beginning of the One Deck (maybe the first 50-100 cards). This was when I was still testing with the amount of definitions that should be added to a card to review comfortably. In these first cards, sometimes there are cards with as many as 2-4 new definitions.

      I was originally going to remove these first 100 cards, because I found that putting this much information into a card was bad. But I left them in there because I wanted to keep the deck as is. The One Deck is a lot more raw than the refined Jalup Beginner/Intermediate/Advanced decks (for example, I mentioned in this post that I did a bit of experimenting with place/people names).

      I do not recommend doing sentences with multiple definitions required unless you further branch them. Maybe, on the rare occasion 2 is okay, but 1 is always the goal.

      So you have two options:

      1. Branch the entry cards with multiple definitions into new cards
      2. Delete or suspend the first 50-100 cards (while the cards branch off from each other, remember that my “core” knowledge going into the decks is not the same core knowledge from the Jalup trio of decks. So either way, towards the beginning you may have to branch even when there is only one definition.)

      • Thanks Adam, always the answer I need to hear. Yeah I only went through about 50 before I got tired. Thought they might end after 500 or so, so didn’t want to sacrifice too many. I forget sometimes that branches are sort of self contained in their own circles anyway. I’ll just keep the ones in the first 100 that can exist on their lonesome, that’s already happened a couple of times in the ones I haven suspended. Some of those early words might come up again, but I can always branch them myself, or search for the words again in the one deck to see if it’s in the first 100 :).

        I won’t bother branching them since there’s like, you know, another 12,000 cards or something like that hahah.

        I don’t know why I keep thinking of your base knowledge being a lot less than the Jalup -soon to be- 3000 so I imagined we’d have close to all the vocab and more going into the one deck. I guess this isn’t going to be case, seeing as those branching methods didn’t have words cherry picked like you’re doing for JALUP pre-mades.

        Thanks for providing another one of the apt responses you’re known for! The best!

        From your first JALUP Advanced customer :P

        • Yeah, the most effective way to use The One Deck is to be selective. Don’t feel guilty about deleting cards that are complex or you don’t like. For example, not everyone cares about having 20 cards from Harry Potter…

          My knowledge base starting The One Deck actually was probably around the equivalent of the Jalup Beginner + Jalup Intermediate (+ maybe going a bit into the Jalup advanced). However, it wasn’t the “same knowledge.” My 2000+ pieces of Japanese probably varied a bit in vocabulary and grammar.

          But an extra 1000 cards makes a big difference, so with the Jalup trio of 3000 completed, the One Deck should not be a problem.

  12. Adshapさん、




    • これは難問ですね。

      Jalup Intermediateは物凄く丁寧に作られているデックです。一歩ずつ前進して迷いがないように指導してくれます。

      One Deckは一言って言えばワイルドです。情報・知識がぎっしり詰まっているけど下準備や工夫をしないと少し圧倒される可能性はあります。


      • 迅速なお返事有り難うございます。



        • 全力を注いで作っていますので価値があると思いたいですね!


  13. I bought this deck sometime last year and went through about 500 cards before giving up and returning to my cosy je deck. My je deck now has over 8000 cards and id say im around level 50 according to the level guide. I spend about two hours making around 100 cards per day. I just dont really know to make a jj deck, the whole process it just confusing and overwhelming. I think im gonna give using your jj deck another go and stick to it this time

      • I wonder if it’d be good to have that posted as an actual article for visibility (or perhaps linked on the One Deck store page?)

        • I do think it could definitely look better and be more organized if it was an actual article. Maybe I should shoot Adam an email about it.

          • Just an idea, but it may prove worthwhile to rearrange the One Deck using the morphman plugin on Adam’s end, and then sell it with that new i+1 order. (The +1 Deck?) If the new order is a definite improvement, this would mean more value and less hassle (toward rearranging things) for the buyers.

            • I’ve had that idea for a while, but since I figured out how to do it myself. I selfishly lost the drive to send the idea to Adam haha. But Jacob is really good with morphman maybe he will do it with the expert 4000 and send it to adam. Could be awesome

              Then again, I do want the expert series to continue regardless. Hope this ‘improvement’ doesn’t hurt its chances.

            • Yeah I have no problem with putting up an article if it is submitted, and/or if someone wants to just send me a Morphman optimized One Deck.

              Though I’m not really sure it would do anything for Beginner, Intermediate, Advanced, and Expert, as the decks were specifically created to only have one unknown element per card that builds on each other. The order is extremely important for these decks, so having them rearranged by an algorithm seems counter productive.

            • at least for me, I only use it to organise the on deck vi my Jalup deck series of cards. My Jalup series order remains unchanged. Though this is mostly irrelevant because I’ve completed those decks. Ideally someone with the entire Jalup series completed would take the morphemes from their deck and use it to reorganise the one deck. This has worked pretty well for me, obviously there is the problem of heaps of names and counters, but it takes a mere second to suspend cards if you don’t find them useful are already known. I’ve had a fairly good experience thuse far.

            • Yeah I think the goal is just to optimize the One Deck to get as close to i+1 as possible for people who have worked through the JALUP 4000.

              I don’t know much about Morphman personally, but from what others have said it sounds like a great way to make the One Deck easier to tackle =)

            • I really like that idea Daniel. The program can be useful in ordering cards based off on someone’s specific knowledge base, but I think this is much simpler.

              I sent a reordered One Deck to Adam, but not based on any prior known cards. This is only because I do not yet have the full Jalup Series of decks yet (I’ve yet to purchase the last 500 Expert cards, but plan to do it soon), and I don’t really want to pick a random amount of cards to base it off of, or to just base it off of the cards that I’ve learned thus far.

              Once I have the full (current) Jalup Series of decks in my possession, I’ll send him a re-ordered One Deck based off all 4000 of those cards.

              Also, I definitely agree that trying to reorganize Beginner, Intermediate, Advanced and Expert would be counter-intuitive as they are already set up in a specific, optimal order.

    • Have you looked at Adam’s Branch Annihilator? He gives a really detailed set of instructions and worked examples of how to do it.

  14. Hi Adam,

    Does the maximum deck in the store include everything or are there things that are left out? If so can you tell what is missing?


      • So, just for the sake of clarity, this deck would include the beginning J-E (with audio) deck and the intermediate deck that comes after that?

        • No this deck does not really include the beginner deck with J-E and the intermediate deck. I think from what I’ve read around the site this is more for people who have completed beginner through advanced or even expert.

          If you want just beginner and intermediate I recommend the battle package since it also comes with advanced for the same price or better yet the maximum package.

        • If you are asking does Jalup Maximum include the beginning J-E (with audio) deck and the intermediate deck after that, this is correct.

          If you were asking whether the One Deck includes those 2, Tyler gave the correct answer. It does not.

  15. I studied Japanese obsessively for years using the AJATT method. Now I have been living in Japan for 2 years, finished JLPT 1 and now work in a company where I use Japanese daily. Would still like to keep flexing them language muscles and get every bit closer to native fluency and thought this deck might be good for that.

    I do have 3 questions though:

    1. Do you think this deck might be useful for a person like me?

    2. Could you give a more detailed breakdown of what kinds of media/situations/themes these cards relate to/are taken from?

    3. Do these cards contain reference to the source they were taken from?

    • In answer to your questions:

      1. Yes, I think that you would find use out of it. However, there would definitely be a good amount of cards you already know if you are JLPT 1 level, so you’d have to delete whatever you don’t need.

      2. There’s just too much to really give an accurate breakdown. It has everything from action manga to books on law and the economy. Love story movies to heavy sci fi.

      3. No it does not.

  16. I just bought this. I could have swore I bought it already years ago and found it too difficult but couldn’t find even a trace of it. :~(. (I kept wanting it and not buying it but broke down and bought it finally).

    I’m not sure what the Morphman version is. How is it different from the original? Is it very much recommended? I get the impression it is so that’s the one I’m using. I’m pretty comfortable using the sansseidoukokugo dictionary but I’m finding the J definitions a little vague.. they seem more like synonyms that were found in google or something instead of a dictionary. One had a typo but in general they seem ok (I’m not too picky about small mistakes since they jump out at me anyway and I can fix them).

    I’m just a little curious because it’s supposed to start with sentences but it’s just starting with short phrases.. ok I’m in bootcamp and I literally forgot how use Japanese input on Windows so don’t mind the romaji. koukiwo hanatsu. It seems like a collocation card almost. I guess it’s technically a sentence.. just a short one. Anyway, so when I don’t understand something I just copy and paste from my sanseidoukokugo app onto the card in the definitions field. I don’t know for sure how you do branching as I haven’t read your article recently but this is working fine. In terms of my ability I’m between N2 and N1 and I’m finding the difficulty very good. I already know or knew and forgot about 10/15 percent of the words so far and the rest are new. I wonder about what level was your Japanese roughly when you started this deck? And what level when you finished?

    • I don’t know if people are reading these comments wondering if the deck is for them.. I would say it’s pretty rough. For example here’s this card:福祉の立ち後れ and the meaning.. 立ち後れ:たちおくれること So it’s basically using the unknown word in the definition. I’m just adding definitions as needed as I go and I still like the deck because I don’t have to mine my own sentences.. I rather dislike that. I know that there’s something to be said for getting your words from your own sources but it distracts from the enjoyment of reading when you do that. And I’m not too discriminate when picking new words to study. You could say I might pick every leech I lay my eyes on. I don’t know how picky Adam was when making this deck but at least the word choices worked for him. I guess I’ll update here a few more times as I study from the deck more.

      • I highly recommend you use this in conjunction with the Morphman plugin, in your own Anki installation. It’s a bit hard to get it setup but it will rearrange the cards according to your own cards (knowledge).

        I think there’s even the possibility to provide it a “priority” text file (a book you’re reading, scripts from movies/anime from your immersion library etc), showing you cards for words that appear in that text file. All in i+1 format. I haven’t played with that part of it yet though.

        • I’ll go check out the Morphman plugin again. I’ve heard of it before but I think it seemed too complicated to me to implement. And it seems it sounds like it’s going to look at my previous anki decks to figure out what I know so as to apply it to future decks maybe… except that I’ve deleted my old decks and I also spent tons of time doing SRS in other apps like Flashcards Deluxe and just Midori (for iOS) and Japanese (for iOS). Without the previous decks to learn from is the Morphman plug in useless?

          I read your summarized blog post about your studies to date and I’m very impressed at your rapid progress. I’ve been studying Japanese for 7 years now. The impressive thing I think is just that I didn’t give up and kept going – no super ability here lol. But I do think I have a vocabulary of 8,000 to 10,000 words or so. Not too shabby.

    • Morphman rearranges the card by i+1 (information + 1), so it is technically supposed to make it easier.

      There are two important things to keep in mind about The One Deck:

      1. It is very raw. This wasn’t created as a polished deck like all the other products on Jalup that guide you step by step. It was what I personally added for my own purposes. So sentences may be long, they may be short. They may be phrases, they be complex. They were what I needed at the time.

      2. This isn’t meant to be done straight through. It won’t work this way. It is meant to have a lot of deletes. You keep sentences you like and remove ones you won’t. Out of the 12k+ cards, you might find a few thousand that you don’t like and you can get rid of and that’s fine.

      • Thanks for the reply Adam. If you could estimate your ability when you started the One deck and when you finished I think that would be motivating for me. I know it was probably a lifetime ago for you so just your best guess is fine. Thanks.

        • – Started studying Japanese around January 2005.
          – Started the One Deck the end of 2007 when I was intermediate level.
          – Continued to seriously add new cards to it for 2 or 3 years.
          – Added sporadically after that from 2009-2012.
          – 2012+ maybe a few cards here or there.
