まいた種は自分で刈れ　　As you sow, so shall you reap.

まかぬ種は生えぬ　　Nothing comes out of nothing.

まさかの友は真の友　　A friend in need is a friend indeed.

三つ子の魂百まで　　The child is father of the man.
What is learnt in the cradle lasts to the tomb.

無理が通れば道理が引っ込む　　Where might is master, justice is servant.

目には目を、歯には歯を　　An eye for an eye, a tooth for a tooth.

目は口ほどに物を言う　　The eyes are the window of the heart.
