I voted "maybe." I can read all the daily use kanji and more, and I think it is MUCH easier to read something in kanji than without, but on the other hand, I think that this may simply be because I am USED to it. If I were used to say, reading everything in hiragana, then that might be easiest for me. They abolished kanji in Korea, and the people do not seem the worse off for it. It seems like there is a bit more freedom when the language is merely phonetic, but it loses some artistic quality.
I do think it might be best to further standardize kanji. As in, make each kanji have only two standard readings--the Chinese reading and the Japanese reading. If the Chinese reading was the same every time for compound words, there would be a lot less confusion. I say this because even though I can read kanji just fine now, occasionally I will come across a compound or rare letter I can't read. Then I ask my husband how it's read...and he never knows either. It is a bit silly to have people who are literate but still cannot read many things. Then again it does add a certain "elite" feeling the more you can read, but it's not that practical. There will ALWAYS be kanji/readings you do not know, even if they are few.
The う/お distinction is also rather useless in situations like...遠い(とおい) and お父さん(おとうさん). The pronunciation is the same, but it uses different hiragana. Unifying this would make the language more streamlined. Ask a Japanese person if they can write 十日 in hiragana. Most will write とうか, which is wrong!
Also, I'm in favor of eliminating katakana. I do not really see the point except to show that something is "foreign," which to me is a really unnecessary distinction. There are situations when katakana is used for emphasis or sound, but it's not enough to justify having a whole 'nother syllabary for. Katakana used to be useful because it was used like hiragana today. Now it's not really useful, though. Eliminating katakana would streamline Japanese.
But those are just my B.S. opinions and I'm really fine with the current system. I just thought they would be interesting ideas. And truthfully, if they changed it now, I would be quite inconvenienced because I learned it the old way. But I do think it would be more practical. But there would be a lot of people angry about it and it would never happen anyway!
