Study by subject
Japanese
In Japanese you memorise kana, kanji, vocabulary and particles. Lumi asks them back until the reading and the meaning come on their own, well before your trip or your exam.

How to turn this subject into cards
Make one card per kana, per kanji and per word, with the reading, the meaning and a short example. Learn the kana first, then kanji one by one, each with a word that uses it. The trap is recognising a character when you read without being able to say or write it. With Lumi you answer from memory before seeing the solution, and that test fixes the reading better than rereading (Roediger and Karpicke, 2006). Keep short regular sessions rather than one big block, because spacing makes you remember longer (Cepeda et al., 2006). Write particles inside whole sentences, not on their own. Add to each card an example from your own life, which makes the answer easier to find again.
What you need to know by heart
- The kana, hiragana and katakana, with their sounds and shapes.
- Common kanji with their meaning and readings.
- Basic vocabulary, each word with an example sentence.
- Particles such as は, が, を, に and で, and what each does in a sentence.
- Polite verb forms and the basic counters.
It depends on the country
Japanese has a well-known language exam, the JLPT, which measures reading and listening comprehension at several levels. You prepare for it with the same cards of kana, kanji, vocabulary and grammar that you make with Lumi. You pick the level you are aiming for, then write the cards that match what the test covers.
How Lumi helps you remember it

You teach your Japanese cards to Lumi, kana, kanji, words, particles. It forgets over time, like you do, then quizzes you right before you would forget. As your exam or trip approaches, the Mist settles over what you know less well and Lumi asks that first. You arrive able to say and recognise, not only to reread.
Example cards
Three cards the way you would write them, with the answer Lumi expects.
What does こんにちは mean?
Hello (konnichiwa).
How do you say thank you in Japanese?
ありがとう (arigatō).
What does the kanji 山 mean?
Mountain (yama).
