Ryakumoji
http://www.omniglot.com/writing/ryakumoji.php Ryakumoji (略文字), from Japanese 略 (ryaku), abbreviation, and 文字 (moji), characters/letters, is a system of writing the kana syllabic scripts of Japanese with fewer characters to r emember. It was invented by Alex DelPriore out of his interest in the Japanese scripts, with both of them as inspiration for the shape of each letter. There are a total of only 17 Ryakumoji: 5 vowels (aiueo), 8 consonants (kstnhmyr), (w)o, hatsuon (ending n'/m/ng sound), sokuon (assimilated sound っ/ッ), and chouon (long vowel mark ー). Also used are the voiced marks, dakuten (゛) and handakuten (゜). It's a syllabic alphabet written left to right horizontally, usually blending one character into the next in a single line. A new line is started if the next letter is "a", if the last letter was "n'" or a sokuon, or if the letters "m", "y", "r" or "(w)o" are encountered. Ryakumoji can be written by considering each character that needs to be represented. Oh my...it's not very nice to look at....or very practical...I almost feel bad looking at it.

Kana actually works for japanese very well, the hard part is the kanji. And Kana actually looks nice. So loosing that is a great turn off. I also did a simplification of kana before, but kept it syllabic, i think that makes sense for the language and the people that cant actually say consonant clusters. So its not that big of an optimization to separate consonants from vowels in japanese as could be in other languages.
