Japanese rules are the rules used in Japan. Japan had no written rules until 1949. They were revised in 1989. The new rules are rather different from the old rules, but have the same effect for nearly all games. Other parts of the world have often also adopted such rules. Furthermore, sets of rules similar to those used in Japan are often casually referred to as Japanese (style) rules.
