Take your Japanese from ZERO to proficient with this single, monstrous Japanese course.

The Hacking Japanese Supercourse (HJS) is a collection of courses covering basic, intermediate, and advanced Japanese.

In 1,000+ lessons, we explore the ins and outs of Japanese (e.g. grammar, natural phrasing, etc.), along with the most effective approaches to learning this fascinating language as quickly as possible.

By making your way through the 10,000+ Japanese sentences appearing in HJS sub-courses — reading word-by-word breakdowns; studying flashcards; listening to native audio for everything; practicing pronunciation; etc. — you are sure to become highly proficient in Japanese.

Niko (NihongoShark's founder) started learning Japanese way back in 2008... and it was a disaster. After a year or so of feeling he was getting nowhere, he quit. Failure.

In late 2012, he reworked his approach to Japanese and he found a system that worked for him. He wrote a blog called NihongoShark to explain how it worked. Within two years of using this new system he had passed the JLPT N1 and landed his first major translation job.

Eventually, he got good enough at Japanese to start providing the lessons he'd always wanted (with the help of some amazing native speakers, of course). Before he knew it, NihongoShark was no longer a blog. He and his team of educators had built a one-stop shop for learning Japanese. They had built the Hacking Japanese Supercourse.

HJS is not for people who just want to pick up a little bit of Japanese before a trip to Japan. We are looking for the students who have a burning desire to get very, very good at Japanese.

In other words, HJS is for serious students. It is for the people that want to become translators, watch anime without subtitles, read light novels in their original Japanese, or just build a life in Japan or surrounded by Japanese speakers.

If you are ready to commit to such an undertaking, then we would consider it a great privilege to guide you on your path to Japanese mastery.

I just couldn't stop myself from writing you an email saying how incredibly useful your course is.

As a person who is very self-motivated, I was sure that I could figure out how to teach myself Japanese on my own. And sure, I probably could have. But my research was so overwhelming...and it is so difficult to find reviews of Japanese programs that are both honest and seem to fit with my learning style, that I was feeling like I was drowning in an ocean of information.

Your course has been a life-saver. I feel sure that I will be successful following your system.

Thank you very much! And best of luck to you in the future! I will be spreading the word."

"Hey Niko,

Finally, I have finished your Supercourse. Here are my impressions:

This course is fully worth the price you're asking for it, and then some.

The way you hold the hand of the language learner in all aspects of studying, all the numerous useful references, and of course the actual ideological framework of the course itself, are terrific.

Everything one needs to learn Japanese efficiently is here. One just has to walk the path laid out in front of him. Even for the more adventurous types seeking their own personalized ways to learn the language.

The 'and then some' part comes in the form of the general light and humorous tone of the guide, which really made reading it easy. I LOL'd in some parts man, seriously.

Your guide has further confirmed that I wanna follow your methods, with some little tweaks to suit some personal preferences. Mostly just in the materials I will study, really. This guide was heaps awesome, and I'll put it to good use.


- Michael B.

"I started off my Japanese studies with the Hacking Japanese Supercourse. It was my only starting resource, and it dispelled all the fears I had about learning the language. Two and a half years later, I passed the N2. I couldn't be more grateful for Nihongoshark, and couldn't recommend it enough."

I just wanted to let you know that I've been studying Japanese for nearly a decade and have been living in Japan for 3 years of that time, so I'm mostly going through the Bunkai Beast as a refresher course. I work mostly with women and small children (I teach at a preschool), so I've heard "の" used at the end of a lot of sentences, but I always knew something was missing in my knowledge since I thought it was just a cute way to ask questions but Japanese people always seemed to struggle to explain it to me.

I actually went through this lesson [on の] a few days back and was like, "Oh wow, that's super useful! I thought it was just baby-talk stuff and that's why people had trouble explaining it" but now I've been through a few classes with this knowledge and I'm just back to report that the lessons on "の" have made my understanding of what's going on around me SO much easier. It's like whole new doors have been opened.

It's also helped me understand more how to use "んです" because I knew it was used in Japanese, but I felt like I never ran into it or what I was told was the catch-all casual version ("んだ"). Which, now that it has been explained to me, is probably because my coworkers are almost entirely female and we all speak pretty casually to each other (the only people who speak formally to me usually speak in English rather than Japanese).

I'm already looking forward to the rest of what you have to teach me.

So yeah, just wanted to say, "Thank you". Like, really actually super-seriously THANK YOU though.

Why it's effective / what's on the inside.

What students say about this course:

What exactly will I learn in the Hacking Japanese Supercourse?

So Many Japanese Courses

  • Over 1,000 in-depth Japanese lessons.
  • 10,000+ Japanese sentences written by native speakers, most of which are broken down in lessons and also provided in flashcards with built-in audio.
  • Thousands of audio loops for studying on the go and pronunciation perfection.

Here's a closer look at some of these courses...

HJS Core

  • This course will help you navigate your ascent to Japanese proficiency. It explains how to get Japanese into your head and how interact with the gargantuan amount of learning materials at your disposal as an HJS student.

Kana Mastery

  • This course teaches you (1) the Japanese "alphabet" (a misnomer, if we're being technical) and (2) accurate pronunciation of the sounds of Japanese.

Bunkai Beast

  • This course is a surgical breakdown of Japanese sentence patterns. In roughly 100 lessons, we cover quite a bit of introductory grammar, including a ton of stuff you won't learn in a textbook.

Kanji Mastery Course

  • In this course, we walk you through two viable options for learning the 2,000+ kanji (=Chinese characters) that you must know in order to read Japanese like a native.

Vocab Mastery Course

  • This course teaches thousands of Japanese vocabulary in full sentences without ever introducing more than 1 new word at a time. It also includes enough notes on words' nuances to fill a textbook of its own.

JLPT N5 to N1 Grammar

  • These 5 courses break down the hundreds and hundreds of sentence patterns you must master to pass various levels of the Japanese Language Proficiency Test (JLPT).

How long will it take to complete all of these courses?

…is a question that we get a lot, and it's a difficult one to answer.

If you start at zero Japanese and study these courses every day, it'll probably take 1-2 years to become OK at Japanese (i.e. complete Phases 1-2) and 3-4 years to become GOOD at Japanese (i.e. complete Phases 1-4).

These numbers vary dramatically based on the person studying and how much time they have available to put in each day.

Rather than worry about how long this journey will take, however, maybe worry about…

Enjoying Your Journey to Japanese Fluency

A message from Niko, the founder of NihongoShark

This photo was taken at a restaurant called Hama-zushi in Sapporo, Hokkaido, Japan. It is a photo full of blessings, many of which I never would have received had I not studied Japanese. The person behind the camera is the love of my life, and I never would have met her without Japanese. (She couldn't speak English when we first met.)

I can go to a restaurant like this, and I can interact with the servers, and I can eavesdrop on the tables next to us, and I can read the menu, and I can share precious, fleeting moments with some truly amazing people... because I studied Japanese. And it's such a rewarding feeling.

At the end of the day, a language is nothing more than a tool for us to communicate with the people around us—to learn from them; to exchange thoughts, feelings, hopes, and dreams. This is the tool that I want to help you attain. I am truly passionate about the Japanese language, and I want to help other people to learn it, too. That's the real reason that I started this site all of those years ago.

If you really want to learn Japanese, I guarantee you that you can, even if you can't afford this course. There is no single indispensable tool for learning something as enormous as a language. Anyone who tries to sell you that promise is probably trying to cheat you out of some money. While our system might make your Japanese studies a lot smoother, faster, more effective, and more enjoyable, there are countless people that have learned Japanese without it.

So, hold on to the dream. Just keep swimming, enjoy this fascinating journey, and I'm sure that you'll have your own Hama-zushi experience someday, too.

Frequently Asked Questions

The course starts now and never ends! It is a completely self-paced online course - you decide when you start and when you finish.

It depends on which plan you sign up for — monthly or annual. All of the flashcards and audio files are downloadable, though. So those are yours to keep even if you cancel.

For annual subscriptions, just send us an email within 14 days of purchase, and we'll issue you a refund. For monthly subscriptions, you can cancel/unenroll any time.

Yes. All credit card payments on our course site are processed by Stripe using advanced encryption technology. Stripe is a secure payment gateway used to process billions of dollars in payments each year for companies like Kickstarter, Twitter, Instacart, and Lyft.

We never personally receive your credit card information.

Unfortunately, no. Our system doesn't allow it. If you do not have access to a credit card but still want to purchase a course, please send our team an email.

Of course! The best way to do this is to join the NS Chat Community (on Discord) and talk to other people learning Japanese. Many of them have purchased HJS.

First and foremost, we do not waste people's time. We never write a blog post or send an email that does not teach at least some Japanese. We do not post articles unless they contain actionable content (e.g. words and phrases worth learning, tools that will improve readers' Japanese, etc.). We do not write clickbait articles that prioritize activity over productivity (we explain the difference in HJS). Our readers have precious little time in each day, and they need to utilize that as well as possible if they are going to learn Japanese quickly and efficiently.


  • We always deliver more value in a course than we receive in monetary compensation.
  • We only allow native speakers to write (or at the very least, approve) Japanese sentences used in our lessons. A native Japanese speaker must also check all lessons for accuracy.
  • We do not shy away from recommending other sites and learning resources just because they are our "competitors." If we find a site or service with top-notch learning materials, we share it.
  • We obsess over making our Japanese learning materials the best on planet Earth.
  • HJS is a subscription service and as such, is continually recieving updates and fixes. The course will only continue to get better as time goes on, through your direct feedback, and as we add more content that we dream of making for you.

Finally, we are not interested in having students purchase our courses, then not use them. For this reason, much of the content that is free on our site costs money elsewhere. A great example is our Kana Course. If a student is going to learn Japanese for a week, then quit, we don't want to take their money. We want the students that are going to achieve a life-changing level of fluency in Japanese — the student that wants to become a translator; the student that wants to talk with friends and family in Japanese; the student that wants to watch their favorite shows without subtitles; the student that wants to read their favorite light novelist's latest work without waiting for a translation. Everything is done with these students in mind.

14-Day Money Back Guarantee*

*For annnual subscriptions

No-Questions Asked

If you are not totally satisfied with HJS for any reason at all, then please email our team within 14 days, and we will immediately send you a refund, no questions asked.
