Those who ever saw Japanese characters hardly will argue that Japanese is a complex language. Moreover, a complex script is not the only peculiarity of Japanese.
Japanese use 4 lettering systems, 3 of which are of their own. However, what seems complex is just beyond the imagination. But for the Japanese those are ordinary things.
First system are logographic characters, the kanji. They were imported from China to Japan from the 4th to the 5th century, because at that time the Japanese language did not have its own characters. The Chinese use these characters, and only they have them.
Two additional types of scripts in Japanese are Hiragana and Katakana. These two kana are simplified kanji characters and they are both phonetic lettering systems. Each consists of 46 characters. They were developed over the years by Buddhist monks.
As already mentioned, there was no writing system before the importing of kanji in Japanese. However, the language itself existed, and Chinese kanji characters were used as phonetic symbols (Manyogana).
Here how Hiragana is used in modern Japanese:
- inflexional endings
- particles
- auxiliary verbs
- conjugation
- some words
Katakana are used mainly for foreign terms and names as well as onomatopoeia.
Romaji, the Latin alphabet, is used to send messages to foreigners.
