Hence, the sound “f” can be expressed by the letter “f” or the combination “gh” as in ‘safe’ and ‘enough’. On the other hand, the Japanese writing system is of the SOV type, [and is] based on three main alphabets: hiragana, katana and kanji. Hiragana is similar to katana in terms of phonetic characters. Hiragana is used for Japanese words and grammar, while katana is mainly used for onomatopoeia[c] foreign words. [Finally, the kanji system is based on] complicated characters mostly from Chinese, [which] represent an idea. [Each character has] two different pronunciation[s]: Japanese, which was formed by matching an already-existing Japanese word to an imported kanji, and Chinese, which was formed by Japanese-izing an already-existing Chinese pronunciation of that character.
