Learn Japanese.By actually reading it.
Read a text. Save the word you need. Write your own thoughts.
Three writing systems, SOV word order, particles instead of prepositions. Japanese is a reader's language — and the only way to internalise it is to read it. Lex is built for exactly that.
近所のカフェで
きのう、家の近くのカフェへ行きました。コーヒーとパンを注文しました。店員は近所のことを話してくれました。そこで新しい隣人に会いました。

01WHY THIS PAIR
Japanese, onesentence at a time.
Kanji you meet in one word appear in twenty others. Particles like は, を, に, で change the meaning entirely. This is the language where flashcard apps fall shortest — and where a reading-first tool helps most. Lex hands you real texts, then lets you save what you meet.

A few good questions.
Yes. A1 texts use mostly hiragana with a small set of core kanji (家, 私, 名前, and similar). You save the words you don't know as you meet them, so the reading and the dictionary grow together.
