About this app

Kotomichi is a Japanese study app for the JLPT N5 and N4, made for learners who study in English or Sinhala (සිංහල). Start from hiragana and katakana, then build the vocabulary and grammar you need for the test, one small step at a time. Beyond the test, learn practical phrases you can use at work, in daily life and with friends in Japan.

WHAT YOU CAN STUDY
• Kana – Hiragana and katakana, including dakuten, handakuten and combined sounds. Practice with flashcards and short quizzes, including look-alike characters that are easy to mix up, such as さ and ち.
• Vocabulary – 1,940 JLPT N5 and N4 words in 82 everyday categories such as family, food, time and work. Mark the words you know, and bring them back to review any time.
• Grammar – 129 N5 and N4 grammar points in 15 stages, in a clear order. Each point has an explanation, example sentences and a short quiz.
• Phrases – 200 practical phrases for the workplace, daily life, chatting with friends, and problems or emergencies, with notes on how polite each one is and when to use it.

STAY MOTIVATED
• A learning map that shows your progress in each part
• Daily streaks and 23 medals earned through real study
• An optional daily reminder, never more than once a day

LEARN IN YOUR LANGUAGE
Choose English or Sinhala for the app. Word meanings, grammar explanations and phrase translations appear in the language you choose.

MADE WITH CARE
The Japanese content is written and reviewed by a native Japanese speaker who researches the JLPT, so the words, grammar and examples match what each level expects. The Sinhala text is checked by native Sinhala speakers, so it reads naturally.
