Tosa-Style Castnetting

By obachan,  Japan

Perhaps cast net fishing is nothing unusual; people in many countries seem to do it for living or for recreation. I even found announcement of “cast net competitions” outside Japan on several websites. However I should say that here in Kochi, they have developed a very unique castnetting culture. Not only they developed a unique throwing style called Tosa-ryu (Tosa style), the enthusiasts in this prefecture practiced on land so hard that they finally turned it into an athletic event, on-land cast net throwing competition called Oka-ami. This “dry” castnetting competition, with the unique, colorful cast nets for “athletic use,” is something you cannot find anywhere else in Japan (or possibly in the whole world?).

This is how an “athletic” cast net (left) looks compared to a regular cast net commonly used for fishing in the river (right). Athletic versions are bigger, all hand-made and not available at fishing-gear shops, according to Mr. K who invited me to see the demonstration yesterday. What they do is that they buy nylon fishing lines at the store and dye them with the colors they like, and make their original cast nets. Those who are not skillful enough ask more experienced people to make one for them. It is said that two to three weeks are necessary to finish one net and it probably costs around 40,000 to 50, 000 yen (apx. US$350 to US$440) to make one. The leads are usually called “iwa(rock)” but in Kochi they are sometimes called “hiru (leech)” because of their shape.

Colorful nets for athletic use

In athletic castnetting, the net must be thrown from a special board which is considered to be the bow of the ship. Mr. K said that here in Kochi, experienced masters used to strictly teach younger members to show respect when getting on the board by taking off shoes and stepping on from rear of the board, not from side or front.

 

Tosa-style castnetting. Now he’s loaded and ready to throw.
See the throwing motion in a slideshow here. To have a sense of continuum, set the speed to 1 second.

It's a little hard to see in the photo, but there are ropes stretched on the ground in a radial pattern to be used as measurement lines. After landing on the ground, the net is measured on certain lines to figure out how far and how wide it spread out, and based on the sum of the measurements, the ranking of the person is decided. The competition is held 4 times between January and March every year (2 throws per person at one competition), and the annual ranking is decided based on the result of all competitions. This is their official ranking list. If you are familiar with Japanese traditional wrestling, Sumo, you might think that this looks just like Sumo ranking list. Yes, they adopted the ranking system from Sumo wrestling.
