ッ (little tsu) is a tiny katakana sign that adds a pause before the next sound: バグ bagu (“bug”) becomes バッグ baggu (“bag”). Small, but it changes everything. And look closely: it’s practically a smiley face. Hence the name.

母語で
Made for English speakers, false friends and all
Plenty of Japanese words come from English, and many of them changed their meaning on the way. The “False Friends” deck collects exactly the ones that trip up English speakers.

よくある質問
FAQ
Do I need to sign up?
No. Open the app and start learning. Your progress is stored in your browser. You only need an account if you want to sync progress between devices.
Does it work without internet?
Yes. After the first visit Little Tsu works offline, and you can “install” it to your home screen from the browser. The one exception is pronunciation practice: speech recognition is done by the browser itself and needs a connection.
I don’t know any Japanese. Where do I start?
With “Hiragana + Katakana”: hiragana first, then katakana. Next, N5 words and grammar side by side, and kanji once you read kana confidently. The “Course” section guides you step by step.
Will Little Tsu prepare me for the real JLPT?
Content is split into levels N5–N1, and the mock exam follows the JLPT structure. But the score is only a guide: it isn’t converted to the official 0–180 scale.
How much does it cost?
Kana and level N5 are free forever. Levels N4–N1 will be part of Premium. The subscription is still in the works, and we’ll announce the price in advance.
