This was our bait, small ebi (shrimp) some of which was still in big frozen blocks. We were provided with professional rod and reels with the weirdest bait contraption I’ve yet seen. At the end of the fishing line was a red lantern thing which you filled with the bait and which had holes at the bottom to let the bait flow out of it. Attached to the lantern thing was a heavy sinker and another line with two hooks, which we also baited with the shrimp. You can see the setup in some of the pictures.
