Kanji Tree




The Japanese writing system is the most complicated one in existence, possibly ever.

There are two phonetic alphabets.  Hiragana is a nice cursive one which is used for writing particles, conjugated verb endings, and things like that.  Katakana is an angular one which looks a bit like Norse runes and used for writing noises, such as onomatopoeia and foreign people's names.  These two are straightforward enough.

Then there's an ideographic syllabary called kanji, which is just mental.  No, seriously.

Readings & Meanings

Each kanji can have a variety of meanings and pronunciations depending on context.  For example, one of the very first ones you learn is :
  • 日曜日 = Sunday
The first is pronounced "nichi" and means "sun", the second one is pronounce "bi" and means "day"!

They can also have multiple pronunciations for the same meaning, take the kanji for "one":
  • 一人 = One person
  • 一羽 = One bird or rabbit
The first is pronounced "hito" the second one is pronounced "ichi".  It's the exact same character with the exact same meaning!

And, of course, they can have multiple different meanings with the same pronunciation:
  • 参る = To go (humble)
  • 参る = To come (humble)
  • 参る = To call
  • 参る = To be defeated
  • 参る = To collapse
  • 参る = To die
  • 参る = To be annoyed
  • 参る = To be nonplussed
  • 参る = To be madly in love
  • 参る = To visit a shrine or grave
These are all pronounced "mairu", you have to figure out which one given the context!

Radicals

Kanji are comprised of component parts called "radicals", and some of these radicals are actually other kanji:
  •  =  + 
If you were learning , then it would be a lot easier if you already knew the other two.
  • 家 = House
  •  = Roof
  •  = Pig, hog.  (archaic term)
So, a pig under a roof is a house.  Sure, it's a little bit weird, but it's certainly a lot easier to remember than a collection of random scribbles.

Unfortunately, the order in which kanji are taught understandably pays more attention to the needs of Japanese children than it does to foreign adults.  So kanji for simple words which a five-year-old could understand are taught early on, and more complex words come later.

Kanji Tree

Faced with the daunting task of learning a few thousand kanji, I naturally turned to my computer for help.  The result is "Kanji Tree".


It's an application for mobile devices, being developed primarily on Android but I'll upload for iOS too when I can get the auto-builder outputting IPA files.  It's still a work in progress, but it's usable right now.

I'm writing it in Unity (of course) and I'll be digging into the problems and solutions I discovered on the way.

I hope someone finds it useful.
