This font is Shuei-Mincho and easy to recognize, but unique a font such as BKIG (Shaken font) is very difficult to recognize.
I heard that a certain operator very quick at typesetting was able to set about 3,500 characters in an hour,
but I set (only typesetting, not composing) about 2,000 characters at my maximum pace.
