I don't think that is because it's old. Take for example Itazura na kiss: manga from the 1991, same as Kanata Kara. In 2008 they made it into an anime. So maybe they couldn't fine someone who would made it into an anime or the author didn't want to I don't know know. But I agree with you that it would be really cool to see the anime of this amazing manga
Man! This is one of the few manga's I read over and over again because I love the story and characters. Why haven't they made this into a anime series yet???
