Nagare bows low as he holds the basket out: containing, as all before it, fresh fish, rice, along with fruits and nuts of the season. Being vastly uninterested in fishing, Nagare can easily make the promise demanded of him.

"You have my solemn word that I shall not fish nor set a toe in this river ever again." An easy promise to make since it's true. Once he's claimed his prize, Nagare has no need or intent to return here. He holds his bow until he feels the basket taken from his grasp.
