Welcome to Onigiri Sensei!
Learn Japanese vocabulary with charming illustrated flashcards, quick quizzes, and collectible Onigiri cards.
Meet your new Japanese tutor. He's adorable, he's dedicated, and he's made of rice.
Onigiri Sensei is a Japanese vocabulary and conjugation app built around beautifully illustrated flashcards. Every word is brought to life through unique 3D scenes featuring Onigiri Sensei — your rice ball guide through the Japanese language.
== ILLUSTRATED VOCABULARY CARDS ==
Each card pairs a Japanese word with a hand-crafted illustrated scene. Visual memory beats rote repetition — words learned this way actually stick.
== CONJUGATION DRILLS ==
Go beyond the dictionary form. Every verb comes with a full conjugation breakdown — plain, polite, past, te-form, tai-form and more. Study the forms that actually appear in real Japanese conversation.
== QUIZ MODE ==
Test yourself with four-choice quizzes covering both meaning and conjugation. Four options. One right answer. No cheating yourself.
== PROGRESS TRACKING ==
See exactly where you stand. Track your overall accuracy, drill down into meaning versus conjugation scores, and monitor every word individually.
GREAT FOR:
• JLPT N5–N4 learners building a solid foundation
• Beginners who struggle to make vocabulary and conjugations stick
• Anyone tired of dry, boring flashcard apps
Japanese doesn't have to be intimidating. With Onigiri Sensei it's illustrated, it's structured, and it's actually fun.
