Japanese is very complicated, not as crazy as Chinese with their phonebook-level alphabet..... Korean is simpler than both I'll agree Korean is pretty simple, but the Japanese syllabary is pretty simple itself:
- Ye, Yi, and Wu don't occur in native Japanese, so don't have characters;
- Wi(ゐ) and We(ゑ) are only used in old Japanese;
- and n(ん) is the only 'stand-alone' consonant and can only end words.
The last three tables are similar-sound transforms by adding ゙◌ or ゚◌ to change the 'voice' of the consonant-part of the syllable, or produce hybrid sounds — kyo(きょ) = ki(き) + yo(よ).
