Started learning hiragana. That's not very difficult and I should be able to decipher - slowly - hiragana in a couple of weeks from now. But I also discovered japanese writing mixes hiragana and kanji to such an extent it's impossible to read japanese knowing only hiragana. I wonder if Japan will some day in the future make the ultimate move to an all-hiragana writing system... After all, the language is not tonal and hiragana is perfectly adapted to it.
