The opening paragraph says that mentsu are divided into shuntsu, koutsu, kantsu and jantou. Jantou has its own chapter. But that chapter says that jantou isn't mentsu. Why's jantou so prominently in the mentsu article if jantou isn't mentsu? Wouldn't that make the division in the opening paragraph a falsehood? --Gwaur (talk) 03:41, 14 March 2017 (UTC)
