Japanese is simpler than you think

Many people think Japanese is incredibly hard because of thousands of Kanji. But speaking and understanding it is much more accessible.

Grammar has no gender, no cases, and verbs don't change by speaker. The pronunciation is simple and regular — once you learn Hiragana, you can read anything.

Focus on Hiragana and the 1000 most common words. That covers 85% of spoken speech. Soon, you will catch words in anime without looking at subtitles.

Hiragana — where Japanese starts

46 phonetic characters. Can be learned in 1–2 weeks. TheLernen has a dedicated Hiragana practice mode.
