-Contents and how to use the app-
Study and enjoy yourself.

Study section
In the study section (‘Let’s Try’) there are four maps: spring, summer, autumn and winter, and you start with spring in the same way as Japanese schools start in spring.
・KOTOBA1 remember words through a game where you match cards with the same pictures
・KOTOBA2 make sentences by matching illustrations of verbs with cards of vocabulary often used with those verbs
・KOTOBA3 choose illustration cards with the same meaning as Japanese character cards and match the cards
・MANGA become characters in a manga, choose the appropriate lines from the choices you are given, and read them out loud
・BUNKA deepen your understanding of Japan through a quiz about Japanese culture and society
・STAGE TEST a review test of what you studied at each stage. 20 multiple choice questions each with four options

-Challenge yourself! -
Test section
There are 16 tests altogether in the test section (‘TEST’). You can take eight of these any one week. The questions change each week. Challenge yourself and check which Japanese vocabulary and words you remember and know with this test. Once you finish the tests, you will be issued with a certificate of results that includes your name. If your percentage of correct answers exceeds 80%, you receive a pass certificate that includes a medal (illustration)!

-A variety of features-
A mini dictionary where you can find all the vocabulary and expressions that appear in the app. Each of the words that you answered that you had remembered have a check mark next to them. In the list each word is also written in Roman alphabet and hiragana/katakana, and there is a translation of the word’s meaning to enable you to study Japanese characters.
Every time you log in to the study section and study, you receive 100 points, and when you take a stage test, that score is added as points. You can see the results of your study to date, including your overall points, your weekly points (total points from the most recent Monday to Sunday), the number of words you have remembered so far, the number of stages you have cleared, and the number of tests you have passed.
Displayed here is the overall point ranking of all learners using this app and the number of stages they have cleared, as well as your own overall points and number of stages cleared.
When you clear the stage test of each stage in the study section, HONIGON’S CAMERA starts up. For each stage various different frames (background illustrations) are displayed, and you can take a ‘celebratory photograph’ combining these frames and a photo of yourself that you take.

I Love This App

Erin Controls you, you do not control her, I swear I’ve seen so many things in this app that has transformed me into only speaking Japanese. Every time I go McDonalds I always wonder where is the bathroom in Japanese to a child. You will know when you know, Erin-san watches you through out this plot heavy blockbuster as you defeat ghosts and fight the McDonalds employees. She is everywhere. On my walls, in my bed, in my brain. She’s inescapable. Please. I beg you. Free me from this eternal torment. I used to have no fear for God’s wrath but since being trapped in this hell we call Erin’s Challenge, I will give my entire being for salvation. Please.

This is possibly one of the best apps in history. I did not choose this app, this app chose me. I now do not only speak Japanese, I also sign in Japanese, speak in Japanese, breathe in Japanese, think in Japanese. This app is the air that I breathe. Thank you Erin-San for blessing this world with your love and hospitality.
You bless me,
A Mortal Soul Made New

Truly a Masterpiece

Truly a masterpiece of the App Store. You do not find Erin, Erin finds you. Everywhere I go looks like Erin. Everything I eat tastes like Erin. Everything I sniff smells like Erin. She has controlled my life ever since I got it. dlǝɥ
