The Gamakatsu "Amago" hooks may look a bit strange, but many tenkara flies in Japan are tied on bait hooks like the Gamakatsu Amago. It is said that the hooks provide more positive hook ups because the tippet is attached to a flexible eye fashioned from silk cord or a bit of mono rather than a hard hook eye. These are barbless hooks, but because of the shape, or the flexible eye, or possibly a combination of both, they hold fish better than the standard barbless "J" shaped hook.
