Stop wasting time on apps that treat you like a child. While other Japanese learning apps busy themselves with cartoon mascots and meaningless streaks, we built something that actually works. Nihon Dojo doesn't care about making you feel good about yourself. We care about making you fluent in one of the hardest possible languages imaginable in two years or LESS! Most Japanese learning apps are designed to keep you subscribed, not to make you fluent. They feed you bite-sized "lessons" that feel productive but teach you nothing useful. They celebrate your "progress" when you've learned to say "I like apples" for the 47th time. We're different. And you'll probably hate us for it. REAL SPACED REPETITION THAT HURTS Through our use of the tried-and-true FSRS algorithm, we will make you review words until you hate them, even if you do learn them a week later. No participation trophies. Here is the twist: we generate sentences using only words you've already learned (revolutionary concept, we know). No more example sentences filled with 20 different N1 words you've never seen before. By giving you context clues that are targeted in real-time at your knowledge, we not only reinforce language in a natural way, we allow you to learn the meanings of new words even when you are seeing them for the first time. Not only that, but our built in formality switching teaches you how Japanese people ACTUALLY talk— learn to be "hip" OR turn so textbook you be start saying させていただきます in your sleep. For the cherry on top, every time you review a word, we will guide you how to write it. If you can call that chicken scratch of yours "writing," that is. Don't worry, we smooth it out for you. GRAMMAR AND CULTURAL THAT MAKES SENSE In addition to shoving words down your throat until you are begging us to stop, we provide structured grammar and culture lessons that build on each other. We're not just here to teach you how to conjugate. We also teach you why Japanese people say what they say. We cover the social rules other apps pretend don't exist, and prepare you for real conversations. You can't learn a language without learning the culture, they are one and the same. KANA PRACTICE FOR VETERANS AND BEGINNERS ALIKE If you're new, there is no easy way to learn and memorize Japanese kana, nor is there a shortcut (except our app, hah). At the very least, we make it sort of less painful to do. With both a rapid-fire minigame and our guided writing practice, you could get kana down in a week or two if you're serious! It's not hard (just tedious), and it works. THE GUARANTEE THAT'LL SCARE YOU Use this app every day for two years. Follow the system. Do the reviews. If you're not (almost) fluent, we'll refund every penny. Most apps won't make this promise because they know their cute gamification doesn't work. We will, because we built tools that do. WHO THIS IS FOR You should use NihonDojo if you want to actually speak & read Japanese. If you're tired of apps that waste your time with pointless games. If you can handle being challenged instead of constantly praised. If you want personalized training that adapts to your actual progress. If you're willing to do work that might not be "fun" but gets results. Don't download this if you want an app that makes you feel good about doing nothing. If you think learning a language should be "effortless." If you need constant validation and cartoon characters cheering you on. If you're looking for a magic bullet that requires zero effort. FREE FIRST Believe it or not, making an app like this is a ton of work, and it only exists due to many long nights, fueled solely by a hate for Anki. While this app is free first (with no ads EVER because I HATE THEM), it costs money to generate sentences and continue to develop new features. Your support is everything to me! HERE'S THE DEAL No BS. Just the tools you need to actually learn Japanese. Download if you're serious. Skip if you want to play games.

NihonDojo.ai ships an update every 6 days, Floonzy every 2 weeks. The most recent releases landed on October 24, 2026 and October 8, 2026 respectively.
