The Most Efficient Way to Learn Japanese Online

Studies show that learning new θͺžε½™(vocabulary) in real context is much more εŠΉζžœηš„(effective) than simply memorizing lists. This method helps you master Japanese naturally.

πŸ‘†

Hover over the highlighted words

πŸ’‘ It's that simple:Just hover to get translation and pronunciation. Reading remains smooth; learning happens subconsciously.

πŸŽ“ Scientific Basis

Why do you forget words after memorizing them?

Because of the lack of Context. We capture i+1 level content for you, allowing you to naturally absorb new words while understanding the text.

Comprehensible Input

Stop rote memorization.True language acquisition only happens when youunderstand the message.

We capture content that combines i(your current level) + 1(a slight challenge).

Easy enough to read, but challenging enough to learn.

Let your brain naturally "acquire" Japanese through reading and understanding, rather than painfully "memorizing" it.

"We acquire language when we understand messages."

β€” Stephen Krashen, Linguist

βœ—Too Easy (i-1):Waste of time, no learning.

βœ“Just Right (i+1):Comprehensible & progressive. Most efficient.

βœ—Too Hard (i+3):Incomprehensible, easy to give up.
