Learn every JLPT N4 word, not just read them.
Vocab Swiper's Japanese deck has every word on this page. You recall each one before you see its meaning, hear it and see it in a sentence, and spaced repetition brings it back right before you'd forget it.

How many words do you need for JLPT N4?
There is no official number. This list has 561 words at JLPT N4, and 1,190 counting every level up to it. Study lists differ in size because each one is compiled independently.
Is this the official JLPT N4 list?
No. The JLPT has not published vocabulary lists since 2010. This list builds on the most widely used community lists, with every reading checked against a dictionary and duplicate spellings removed.
What is the fastest way to learn these words?
Test yourself rather than re-reading. Trying to recall a word before you see its meaning, then reviewing it again just before you would forget it (spaced repetition), takes far fewer reviews than reading a list over and over.
Level lists based on Jonathan Waller's JLPT resources (tanos.co.uk, CC BY). Readings and meanings checked against JMdict (Electronic Dictionary Research and Development Group, CC BY-SA 4.0). The JLPT has not published official vocabulary lists since 2010, so no list, this one included, is official.
