A Japanese learning app focused on efficient vocab/grammar acquisition
Hey HN, it’s been 8 years since I posted on here about the launch of my Japanese dictionary app Nihongo [0] and I’m finally back with a new app: Nihongo Lessons! Think of Nihongo Lessons as the textbook to Nihongo’s dictionary. It’s an app for learning Japanese, specifically made for learners who are serious about becoming fluent, and want a guided set of content that will help them efficiently acquire vocabulary and grammar. The project came about when Adam Shapiro of Japanese Level Up (Jalup) [1] announced last April that he was shutting Jalup down. As a fan of Adam’s work I was bummed to…
In plain words
Nihongo Lessons is a Japanese learning app designed for serious language learners aiming for fluency. It provides structured, guided content focused on efficient vocabulary and grammar acquisition, functioning as a textbook companion to the existing Nihongo dictionary app. The app incorporates content from Japanese Level Up and targets learners who want a systematic approach to Japanese language study rather than casual learning tools.

In the maker’s words, at launch
Hey HN, it’s been 8 years since I posted on here about the launch of my Japanese dictionary app Nihongo [0] and I’m finally back with a new app: Nihongo Lessons! Think of Nihongo Lessons as the textbook to Nihongo’s dictionary. It’s an app for learning Japanese, specifically made for learners who are serious about becoming fluent, and want a guided set of content that will help them efficiently acquire vocabulary and grammar. The project came about when Adam Shapiro of Japanese Level Up (Jalup) [1] announced last April that he was shutting Jalup down. As a fan of Adam’s work I was bummed to hear the news, but realized I actually might be one of the few people in the world in a position to keep his work alive. So I reached out, and we came up with a deal where I would sell Jalup content in my apps. Originally it was envisioned as an add-on to Nihongo, but after starting to build this out it became clear that from a UX perspective it felt too bloated and tacked-on to just shove Jalup into Nihongo. Plus, given that Jalup is built around one-time content purchases, and Nihongo is a subscription, the purchases involved would feel convoluted, and people might be upset that they weren’t included in the Nihongo subscription. So, I started building a separate app that would become Nihongo Lessons. From a technical perspective, Nihongo Lessons is actually just a different entry point into essentially the same app bundle as Nihongo. This gives me a lot of the infrastructure (sync, error reporting, screenshot generation, etc.) of Nihongo for free, and makes it easy to share UI, which I do a fair amount of (flashcards, tutorials, settings). Everything that actually changes behavior between the apps is stored in a single file as an “app variant” configuration, so if I decide to create another companion app in the future, it should be even easier. It’s iPhone-only for now, but iPad will be coming soon. No plans for an Android release at the moment.

I've been fascinated by the Japanese language and culture for a while now, and I wanted to create a simple, no-fuss way for beginners to get started. So, I built *[Nihongo](https://nihongo.site/)*, a free and open-source web app designed to help you learn the fundamentals of Japanese in about a month. The name of the app, Nihongo (日本語), is the Japanese word for the "Japanese language." You can check it out here: *[https://nihongo.site/](https://nihongo.site/)* And for those who like to tinker, the code is available on GitHub:…

The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community. Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned. But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion…
