i don't know why people have trouble with this. Japanese is actually much more simple to say when reading because they kept it very phonetic. the Japanese system is based off of A-I-U-E-O. they sound like AH-EE-OO-EH-OH. most characters follow this principle. a basic alphabet looks like this,read right to left of course:
N WA RA YA MA HA NA TA SA KA A
-----RI----MI HI NI CHI SHI KI I
-----RU YU MU FU NU TSU SU KU U
-----RE----ME HE NE TE SE KE E
--WO RO YO MO HO NO TO SO KO O
N and WO are the only weird ones really. N is used in places where NA NI NU NE NO wouldn't work and just sounds like n. and WO can change its sound based on how its used.
all other letters and sounds are made via small changes(for instance, GA in Japanese is written KA",and things like KYA are written KIya, in this case a little YA)or with puctuation(extending the sound of a word with - after it or on it to emphasize the sound.)
since its written manga it is pronounced as such. there are harder words and rules i won't get into.
edit: the thing just wont cooperate lining up my little chart, but you can line it up easy enough XP
