This is the most complex kanji with a whopping 84 strokes. It is composed of three "cloud" (雲) characters on top of a triple "dragon" character (龘). Also meaning "the appearance of a dragon in flight", it has been pronounced おとど otodo, たいと taito, and だいと daito. According to this site http://learnjapanesepod.com/the-most-complex-kanji/) the kanji was invented by a playwright for a play during the Edo period. However this fact hasn’t been substantiated so it is doubtful as to whether this could be recognized as an official kanji.

Katakana Analysis

The use of Katakana is wide and varied. The 46 characters are not only used for the writing of foreign words in order to make them loaned words, they are also used to express emphasis. Katakana is also utilize to create onomatopoeic words, which the Japanese language is filled with. This set of characters has another function and that is to lend sophistication to a given publication. In most of the fashion magazines the entire thing is filled with katakana words even when there is a Japanese word for it they will tend to simply use the English equivalent. The increasing used of katakana within modern Japan is rather interesting and it sheds some light to the complex history of the language.

The reason why there are several uses for katakana is to allow greater flexibility within the language. This allows Japanese to adapt to changing situations. Different books explain katakana differently because the uses of it are so varied that multiple explanations are possible.
