Peace, Japanese Style
When everyone has grain in their mouth, you will have peace. That is the Japanese style of doing things.
Imagine Japanese people with grain in their mouth. The whole country is at peace.
わ, お
なご, やわ
かず, より
Peace is the Japanese style. The walruses (わ) living off of Japan see this, and start to emulate.
The walruses also achieve peace by putting grain in every walrus' mouth, following the Japanese style.
