Fuda Ninja turns any vocabulary list into a printable page of stickers — because language learning shouldn't cost a subscription, live behind a paywall, or vanish the moment an app shuts down.
We started with a single sheet of JLPT flashcard stickers scribbled together for personal study — a way to peel a word off the page and slap it onto a mug, a mirror, a laptop lid, anywhere it would nag you into remembering it. It worked embarrassingly well. So we kept going.
The mission is simple and a little stubborn: build free, sharable language-learning tools and give them away, in full, forever. No trial period. No "premium tier" hiding the good word lists. No account required to print a sheet of stickers. If it helps someone learn a language faster, it belongs in the open, not behind a login screen.
We believe the best study tool is the one you actually use — and nothing beats a sticker staring back at you from the fridge every single morning.
Every generator, every word list, every printable sheet — zero cost, zero catch. Forever is a strong word and we mean it.
This exists because helping someone learn faster feels good — full stop. If a sheet of stickers makes your study session a little easier, that's the whole win condition.
Stickers work because they're annoyingly visible. Category color-coding, readings, and romaji all exist to shrink the gap between seeing a word and knowing it.
No accounts, no tracking your progress to sell you something later, no vanishing content. Print it, save the PDF, keep it as long as you like.
This is a small, hand-built project — not a startup chasing growth metrics. Feedback, typo reports, and word-list requests genuinely shape what gets built next.
Whether it's JLPT vocabulary or endangered Uchinaaguchi words, the goal is accuracy and respect — not just filler content to fill a page.
Fuda Ninja will never charge for a generator, a word list, or a printable sheet. Small ads and the odd cup-of-coffee donation keep the servers humming — but the tools themselves stay free, open, and yours to use however helps you learn.
Print a sheet, stick your words somewhere you'll actually see them, and let a little bit of chaos do the memorizing for you.
