How it works

Method


Whether you study for an upcoming test or see it as a life mission to memorize all 2136 jōyō kanji, you will run into the problem of memorizing kanji. To learn them you have to have a plan and the right tools. Kanji Book will assist you in your kanji studies.

Our method involves the use of mnemonics. They are small tales which help the memorization of abstract concepts by connecting them to already known facts. For instance, in school you might have encounterd a sentence like “ My very educated mother just served us nachos” to remember the order of the planets in the solar system. Here, each initial letter represents the name of a planet, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Radicals & Kanji


Radicals are the building blocks of a kanji. A kanji can consist of 1, 2, 3 or more radicals. Each radical consists of several strokes. As you can see, to encode as many meanings in a script you have to use more radicals which means there will be even more strokes involed. Unfortunately, the human brain isn’t made to remember complex structures efficently if there is no meaning associated to them. Hence we use mnemonics to associate a meaning to a kanji’s building blocks.

Kanji & Vocabulary


If you look at a Japanese dictionary, you will notice that words consist of mostly 2 or more kanji. Japanese is a compound heavy language where it’s rare that a word consists of a single kanji. Therefore it does not suffice to learn kanji by themselves but to learn the words too. To make matters worse, the pronunciation of a kanji can vary depending on its position in a word. Therefore we have to come up with a strategy to remember them. Mnemonics can help here as well.
