japanese musicians

These lovely Japanese musicians are on a journey, carrying their belongings in bundles. After playing for a wedding in a nearby village they are making their way home. They have stopped at the edge of a stand of bamboo to rest and have tea. While waiting for the tea, they are playing for their own entertainment. No harm will come to them in the peaceful countryside.

Their names, from left to right, are Jin, which means gentleness; Chizu, a thousand storks; and Sen, wood fairy. Their lives are devoted to their music and simple pleasures.

What is Jin thinking about?
