While browsing Japanese Amazon for Tenkara rods I came across this listing from Nissin of what appears to be Tenkara rod with a titanium scoop on the end.
I was curious so I did a few searches. After reading the reviews translated to english, Started to zero in it with keywords ladle, japan, fishing, then found a result with the word burley or berley and searched with japan, fishing, burley.
