How To Identify A Kanji That You Don’t Know

You’re sitting there staring at this (probably ancient alien origin) kanji character, and you have no idea what it means. Like nada. Nothing. Zilch. No matter how deep your probe your brain nothing will come out. Congratulations. You have successfully failed at identifying a kanji. Don’t worry, though. It happens to the best of us. I mean, everyone except me, of course. Ever since using WaniKani I’ve basically become a kanji master (warning: obvious self-promotion alert), but whatever, you don’t have to say I’m hoopy frood or anything in the comments unless you really want to.

Anyways, I digress. Not being able to identify a kanji. It’s a rough problem, though there’s different levels to it. Sometimes the problem is easy to solve. Sometimes it’s not. Let’s start with easy and move our way down.

Identifying Typed-Out Kanji

This is by far the easiest. If you need to identify a kanji that’s accessible via your computer you just copy it (that’s ctrl+c or cmd+c after selecting said kanji) and then past it (that’s ctrl+v or cmd+v) into the dictionary of your choice. For me, when it comes to simple stuff like this, my dictionary of choice is

Upon pasting  a kanji into the kanji section, you’ll get lots of information about it, including it’s meaning, reading, name-readings, number of strokes, and so much more. Basically, everything you need in order to identify a kanji.

How easy. Let’s move on to something more exciting.

Identifying Handwritten Kanji

Here’s where it starts to get fun. You have yourself some kanji that’s not typed out. Perhaps it’s a handwritten letter. Perhaps it’s manga. Maybe it’s Japanese subtitles. Whatever it is, you’re not going to be able to copy/paste yourself to kanji identification victory. So now what do you do? There’s a few options, some more free than others. Radical Search

Back to Jisho, again. On Jisho there’s a radicals search option. Now, keep in mind that the radicals that jisho uses may be different from the ones you’ve seen in other places. Jisho uses the official radicals plus a few extra. For the most part you should be able to find what you need to look up any kanji, though.

Depending on your level of Japanese, this may be fairly easy or somewhat difficult. Don’t worry, with practice it gets easier and easier. Let’s say you have the kanji . This kanji is made up of a few radicals. The hardest part for beginners is knowing what constitutes a radical, though. The best way around this is to start off with something simple… something you know is a radical. For example, in the kanji , is a pretty obvious radical. It’s simple, it’s off on its own, and it’s to the left, which is sometimes a good sign. Let’s then click on the radicals chart, then see what happens.

Wow, that’s still a lot of results! But, you can see that we’ve narrowed down the radicals at least. Now you can see all the radicals that never show up in a kanji with the radical have grayed out. This means there are fewer radicals to choose from, making it easier. At this point you have two options. 1) You can find the kanji in the list results down below (count the strokes and find the corresponding number to make the search faster) or 2) you can put in another radical. Let’s do option number two, just for the sake of practice.

The next radical is up in the top right. It’s there twice, but you only need to click the radical one time in jisho and it counts for both. When you do that, you’ll find the kanji you’re looking for. No other kanji uses the and radicals together in one kanji, meaning it’s the only result.

Click on the kanji and you’ll find the droids you’re looking for. That wasn’t too bad, was it?

Physical Kanji Dictionary

There are times, though, when you don’t have access to a computer or smartphone. When those end-times come, you may find yourself with a physical kanji dictionary and a kanji that you don’t know.

To look up a kanji using a kanji dictionary, there are three strategies that you can use. They are:

  1. Look up the kanji via a radical
  2. Look up the kanji via its reading
  3. Look up the kanji via the number of strokes it has

All three of them can be somewhat tedious (especially number three) if you’re used to using a computer, but 貧乏s can’t be choosers, as they say. Let’s go over each one:

1. Looking Up The Kanji Via A Radical

When it comes to paper kanji dictionaries, you only get one shot at choosing the correct radical. With every kanji there’s a single official radical. Although this is completely different to how we teach it here (sorry for being confusing now), this is the way most people do it. In fact, when talking about “radicals” most normal people think of it this way. Just one radical per kanji, and its only real use is to look up said kanji in a paper dictionary (whereas we use the radicals to learn the meaning of the kanji and to create a more solid memory).

But how do you know what the radical is for a kanji? That’s a good question, esteemed Tofugu reader. Usually you can identify it by looking for one of three sections:

  1. The left side of the kanji. For example, has the “water” radical on the left side, which is those three splashy drops.
  2. The top of the kanji. If something covers the entire top part of the kanji, that’s probably the radical. For example, the bar on the top of would be the radical used to look up that kanji.
  3. Something that surrounds a kanji. For example the whole top left thing that makes up the outside of that kanji would be the radical.
  4. Or, sometimes the radical is just about anywhere. Seriously, radicals are evil sometimes. Look for a simple yet distinct part of the kanji. If you’re lucky, this will be the radical you’re looking for.

A lot of this also comes down to experience as well. The more you look up, the easier it will be to identify radicals. Most kanji dictionaries will list all the radicals somewhere and order them by stroke order. Then, you find the radical, see what page it starts on, then jump to that page in the dictionary. Once there, you flip through the kanji that use that radical and find the kanji you’re looking for (usually these will be ordered in terms of stroke order as well).

For a list of these types of radicals, check out here or here.

2. Looking Up The Kanji Via Its Reading

Also in a kanji dictionary is the ability to look up a kanji via its reading. In the case you know a kanji’s reading (or are able to guess it based off the radicals it uses), you can look up a kanji in a kanji dictionary via the reading-lookup section. This will have various readings and then list out the kanji that use that reading. You can then simply scan through the listed kanji to find what you’re looking for.

3. Looking Up The Kanji Via The Number Of Strokes It Has

Last but not least… okay, it’s least… is looking up a kanji via the number of strokes it has. Most kanji dictionaries will have a section that just lists out every kanji with X number of strokes. Is looking up a kanji this way incredibly tedious? Yes. Is it good for when your radical radar fails you? Also yes. Hopefully you don’t have to do this too often, because it’s a pain, but it is there just in case you need it.

Write It In

The last way to identify handwritten kanji is to write it in yourself. There is unicorn powered software out there that will take what you write and then try to identify it. Sometimes it works well, sometimes it doesn’t work at all. It really depends on what you’re using and how good your kanji looks. Let’s look at a few options, though this certainly isn’t all that’s available.

1. Ben Bullock’s Handwritten Kanji Recognition

This website lets you write in a kanji with your mouse. It actually doesn’t do too bad of a job figuring out what you’re writing, so long as you don’t butcher the kanji too badly. Stroke order is taken into account too, so be sure you know the basic stroke order rules. One particularly nice feature is the “look ahead” check box. This means it’ll spit out kanji that you could be writing well before you’re done writing it. For example, you can see I was writing in the box, but kanji like also come up, just because I could have been writing that kanji too (but the best result, still shows up first).

2. Kanji Sonomama Rakubiki Jiten

If you happen to have a Nintendo DS, this is a pretty sweet “game.” Well, actually it’s a kanji dictionary, but whatever. Besides just being a dictionary, it also lets you write in kanji to look up what it is you’re looking for. Using the stylus and the stylus pad, this is actually really good experience, definitely one of the best “write in kanji” apps out there.

It is however a Japanese game (will still work on your non-Japanese DS) so it’s harder to come by. You can get it on Amazon or (currently sold out). If you already have a DS of some kind this is cheaper than shelling out for a “real” electronic dictionary, though less full-featured.

3. iPhone, iPad

You can add new input keyboards onto your iPhone or iPad in the settings section. Just go to Settings > General > Keyboard > International Keyboard. Although it’s not a Japanese input, technically, adding the Chinese Handwriting keyboard will allow you to actually write in any kanji using your finger. Then, when you write it in you’ll be able to input it into whatever app you’re writing on (let’s say Notepad for this example). This is a nice easy way to identify a kanji you don’t know if you’re an iPhone owner. Just copy the kanji you’ve written into a Japanese dictionary and you’ll have your answer.

Can you do something like this on Android? I don’t know, so put it in the comments and let us know!

4. Electronic Japanese Dictionary

Many people also love their electronic kanji dictionaries. If you’re serious about studying Japanese, you’ll want one of these (many people say). I don’t totally agree, and I think most people can live without, but if you’re in the market for an electronic Japanese dictionary, you can consider getting one that has a stylus that lets you write in kanji, kind of like with Kanji Sonomama (up above) but fancier.

That about does it. With these strategies, you should be able to identify just about any (legible) kanji out there, whether it’s written down or typed down. Any other forms of Japanese lookup that you recommend to your fellow Tofugu readers? Any kanji dictionaries that have done you good over the years? Share them in the comments below and the great Tofugu will surely look kindly upon your souls.

    both descriptions of your posts say ‘parent’ though

  • Mark

    That was very informative AND clever. Thank you

  • Akenabi

    I don´t know whether it´s the same or not, but personally I really like “The Kodansha – Kanji Learner´s Dictionary” if it absolutely has to be a physical one.

  • klanae

    Great article…I think you mean paste instead of past in the second sentence after the first picture. Looks like commenters listed some great resources too. Thanks for all you guys do!

  • lalala

    I’m Chinese, so how i know a lot of kanji……the only problem is the pronunciation… which i usually base off of chinese pronunciations XDD
    but thanks for the tips tofugu! :D

  • Peter Andrew Stanton

    Paragraph 2: there’s -> there’re
    Paragraph 3: past -> paste
    Paragraph 6: there’s -> there’re

    Please thank you.

  • Tom Roseveare

    Apologies if been said, but Google Translate for Android is pretty amazing for Japanese since the latest update. You can draw in multiple kanji at once and the app has no problem getting the result. And of course, it translates on the fly, let’s you listen to the result too. I would assume kanji writing rules apply, but they’re fairly easy compared to mastering kanji itself!

  • Ilovesummer

    a million thanks to you

  • karolla

    very good :)

  • Mohammed Bastaki

    Thanks that’s an awesome article!!

  • bryce

    I want to know the symbol for family over everything. Can anyone tell me the specific symbol

  • Mike Carpio

    I have some kanji characters which I found inscribed on a stone in our lot. Please, I needs someone to interpret these symbols for me. Thanks. Below is my email address:

  • clausangeloh

    Please -insert comma- thank you.

  • Peter

    Perhaps I should have made the intended reading clearer by using “plzthnx”.

  • clausangeloh

    Perhaps that would have been more appropriate.

  • jonesy974

    I have a question about Kanji maybe someone can answer: I’ve read some comments in Kanji on Facebook pictures and whatnot and when I click the little translate with bing link, a lot of them have the phrase “month sauce”. Is this a literal translation that means something else in Japanese or is that a mistranslation of some sort?

  • AndromedA

    Just discovered this place. Thank you!

  • Sofia Rodrigues

    I tried pretty much all the steps listed above, but sometimes the font is being so tricky that it just doesn’t work at all to try to track it through radicals or drawing the kanji. The only way that worked for me was through the program kanjitomo that identifies Japanese characters from images. @_@

  • claire

    Hi I’m not a language student at all, But I have this bracelet that I would like to get identified. I’m not certain it is Japanese, but I was hoping you could help identify the symbol. I can’t seem to find any site that can help me identify it. Please help.

  • Beibii

    Guys can you understand those words in the image? I really can’t read it
