Satsuma. It used to be only a Japanese orange, but now it’s a typeface as well. A rather unusual typeface. Satsuma is rough around the edges, squarish and playful. It is handmade and comes with over 400 interlocking ligatures. If that ain't fun, I don't know what is!
Of course, Satsuma comes with extensive language support AND accented ligatures! Due to the complexity of this font, it only comes as TTF.
