Learn 1,000 Japanese Words Without Losing Motivation

Most people quit Japanese before they learn enough words to do anything fun with the language. WordSen gets you through the hardest part (the first 1,000 words) by turning studying into a cozy game with a virtual pet fox.

You know this cycle

You download a language app, learn a few words, feel great. A week later the flashcards pile up. You miss a day. Then three. Then you've got 200 reviews waiting and opening the app feels like punishment.

You stop. Six months later you try again with something new. Same result.

The problem isn't the flashcards. It's that nobody's solved the motivation part.

How WordSen is different

1,000 Words. Clear Finish Line.

Other apps throw thousands of random words at you with no end in sight. WordSen focuses on the 1,000 most common Japanese words, enough to understand most everyday conversations. Learn 5 a day and you're done in 7 months.

A Fox That Needs You

Study flashcards, earn energy, take care of your Kitsune (a supernatural fox from Japanese folklore). It's a cozy game built around your study habit. When motivation runs out, and it will, your fox gives you a reason to open the app anyway.

Your Flashcard Hub

I use Pimsleur and NativShark alongside WordSen. Neither one has a flashcard option worth using. When I hear a new word in a lesson, an anime, or a conversation, I just record it and WordSen creates a full flashcard with audio and example sentences. Keep using whatever tools you love. WordSen is where all that vocabulary comes together to actually stick.

Flashcards built to remember

Every card has full Japanese sentences (not just isolated words), furigana above all kanji, male and female audio, and space for your own custom image. That last part is a big deal. Taking a photo for each card ties a real memory to the word, which is proven to improve retention.

Meet your Kitsune

Inspired by the Tamagotchi games I loved as a kid. Study with WordSen and you earn energy to feed your fox, teach it tricks, and decorate its house. The more you study, the happier your Kitsune. Miss too many days and your fox turns to stone. (You aren't a murderer... are you?)

KITSUNE GIF A short GIF of the fox in its decorated room. Show the fox eating a treat, walking around, or doing a trick. This is your biggest visual differentiator. Make it look cozy and cute.

Add words in seconds

Watching Spy x Family and catch an interesting phrase? Just hit "add a word" and say it into your phone. WordSen uses AI to figure out what you said, generates audio from native speakers, builds an example sentence, and adds it to your study list. The next time you study, there it is.

Built from experience

During my first trip to Japan I knew about 200 words. That was enough to order food, ask for directions, make (very!) small talk, and even handle a phone call where the operator spoke zero English.

If 200 words can do that, imagine what 1,000 can do. I'm building the tool I wish I had when I was starting out.
