About this app

Have you memorized countless vocabulary words, only to find yourself speechless in Japan?

KOKO specializes in curing this "understands what you read but can't speak" problem. We don't teach grammar or technical terms; instead, we give you a single, practical Japanese phrase each day. Through games, we help you repeatedly break down, reassemble, and speak the phrase until it becomes second nature.

【Open the App, and you're in Japan】 Starting with arrival at Narita Airport, taking the train, shopping at convenience stores, ordering food at restaurants, staying at hot spring inns, strolling through shopping streets, visiting shrines, shopping at drugstores, and stepping into izakayas… 10 chapters, 100 real-life scenarios—each lesson features conversations you'll actually encounter in Japan.

【One Sentence a Day, Really Useful】 Each lesson revolves around a core sentence:
✦ Contextual Story Immersion — Talk to NPCs, the story calls your name
✦ Sentence Deconstruction and Reorganization — Sentence ordering, word substitution, particle filling, error correction
✦ Tense Change Practice — Turn one sentence into ten
✦ Read-Aloud Correction — Speak aloud and compare pronunciation instantly
✦ Boss Challenge — Directly type out the Japanese text from the Chinese text, no hints provided

【No Need to Start from Lesson One】 9-question entrance test; skip chapters you already know. Grammar points forgotten halfway through can be easily accessed in the Grammar Review Center.

【Wrong Answers Don't Get Forgotten】 Weakness Training records the questions you missed, ask them again in a different format, and remove them from the list only after you get them right. Monthly learning reports show you where you're strong and where you're still struggling.

【Designed for Taiwanese Learners】 ✦ Full Traditional Chinese Interface ✦ Content corresponds to JLPT N5–N4 grammar points and has been proofread chapter by chapter by native Japanese speakers ✦ Chapter-by-chapter exams to assess learning outcomes ✦ Daily reminders at your own pace to help you develop a study habit

【Free to Play】 The first chapter is completely free, and you unlock 2 new lessons every day thereafter. Upgrade to KOKO PRO for ad-free, unlimited play: ✦ Unlimited weakness training (free version: 1 time per week) ✦ Complete monthly learning report ✦ 2 Streak attendance cards per month, continuously recording missed days ✦ Cloud backup, progress follows your account

Monthly and yearly payment plans are available; yearly payments include a 7-day free trial.

From the "Sushi Daily Checkup" development team. Vocabulary memorized, time to speak!
Open the app and you're in Japan! Just 5 minutes a day, one useful Japanese phrase. 10 real-life scenarios x 100 lessons, with Shiba Inu Koko to help you speak Japanese.
