So, I'd like to try this and I think it's a viable approach... But a language, especially one with a different script that I can't read, really needs some audio clues too, because that's a big thing that'll help to be able to internalise a word. I mean I can guess banana from the picture and the repeated na sound, but I have absolutely no way of internalising the other characters. I know of the existence of katakana and hiragana, but I don't actually know any characters, and if you intend this to be teaching the language, you need some way of teaching the basic building block you're relying on. Also, as I'm learning Chinese, the kanji aren't really a problem and actually I can guess the meaning, but even then I can't internalise the kanji in Japanese with no idea what it's supposed to sound like. At best, it'll just be Chinese plus squiggles. To me it'd just be "yuan mmm banana mmm shi mmm mmm". If the goal is only to read, then I guess eventually you might start to recognise some of the grammar characters. But if the goal is to learn the language, and presumably to speak it to, then I don't see how this can succeed. Unless of course, I'm missing something obvious and there is supposed to be audio...
