So I took a few years of Japanese in highschool. I remember only a tiny bit of Japanese. But I can tell, in the opening screen title card thingy of Doubutsu no Mori, that the "doubutsu" (animal) is spelled out in hiragana while "mori" (forest) is a kanji character. Why is that? Is the kanji for "animal" harder for kids to read than the one for "forest"? Is it a stylistic thing?
