Sentences

Paste a whole sentence. Read every word of it.

Himotoki splits a Japanese sentence into its words and looks each one up, so you can go from a line in a manga, a menu or a message to what every part means. Conjugated verbs lead back to their dictionary form.

The sentence 猫が窓から外を見ている split into words, with dictionary entries for 猫 and が; tapping 見ている shows its dictionary form 見る

Translate

Translation that runs on your phone.

Download the Japanese language pack once and translations happen on your device, even without a connection. Then read the result word by word, with readings and romaji. Tap any word to see what it means.

The language pack downloads, 毎朝コーヒーを飲みます is translated as I drink coffee every morning, and tapping 飲みます opens its entry, 飲む, to drink

Flashcards

Every word you save becomes a flashcard.

Reviews are scheduled with FSRS, a modern spaced-repetition algorithm, so each word comes back just before you would forget it. Add your own notes, study in both directions, and watch your streak grow.

A review session: each card shows a word, flips to its meaning and an example sentence, and is graded Good, until all four cards are done

JLPT

The lists are built into the app. Browse them in あいうえお order, jump straight to a row, or filter by word, reading or meaning, then save what you want to learn.
