KeiGo JP is the friendly way to learn and look up Japanese business keigo — the honorific language that makes all the difference at work, in interviews, and in formal situations. Every entry shows the three keigo registers side by side, so you always know which form to use and when: • 尊敬語 (sonkeigo) — respectful language for superiors and customers • 謙譲語 (kenjougo) — humble language for talking about yourself • 丁寧語 (teineigo) — the polite です/ます foundation WHAT'S INSIDE • Searchable reference of 100+ everyday verbs and 60+ business expressions — greetings, apologies, requests, and more • Tap-to-hear audio pronunciation for every form • Quiz — multiple-choice practice that adapts to the verbs you find hardest • Flashcards — flip, self-grade, and build a review streak with spaced repetition • Pattern Guide — learn the rules behind keigo, not just the words • Stats — track your accuracy, daily streak, and progress over time DESIGNED TO BE SIMPLE • Works completely offline — study anywhere • Optional auto-play audio and dark mode • No account, no sign-up WHY KEIGO JP Keigo is one of the hardest parts of Japanese to get right, and getting it wrong stands out. KeiGo JP turns it into something you can actually practice a few minutes at a time — look up the form you need in the moment, then drill it until it sticks. Whether you're preparing for a job in Japan, studying for the JLPT, or you just want to sound more professional in Japanese, KeiGo JP helps you speak with the right level of respect — every time.

  • This app hasn’t received enough ratings or reviews to display an overview.

Flashcards now tell you which register they want. Many verbs have more than one correct keigo form, so a card asks for the usual form unless it says otherwise — "Less formal", "More formal" or "When granted". The guide explains what each label means, and word pages now show the register beside every alternative form. Six more verbs have humble-form cards, and a number of respectful and humble forms were corrected.
