My husband or my prisoner!?

Do you know that there are more than 1,000 sounds (pronunciation) in English?
Compare to that, there are only about 100 sounds in Japanese.
(46 sounds from あ to ん plus 25 sounds of voiced consonant like が・ぽ and 33 palatalized consonant like きゃ・じゅ・ぴょ.)

Correctly, as phonetics, there are some exceptions, like ん(n) in まんが(manga) is different from ん(n) in ふじさん(Fuji-san).
But basically, each hiragana / katakana always describes same sound.
I think this is one of the most different points between alphabet and Japanese writing system.

The good point is that if you can read hiragana / katakana, it’s easy to know how to pronounce the word and it’s only 100 sounds.
The difficult point is that there are so many same or similar sound words in Japanese!
