In the Ariake Sea, which produces the largest volume of nori seaweed in Japan, Mr. Toshiki Kume has engaged in the cultivation of nori for thirty years, and his son Mr. Yuki Kume is now working with him. They have the newly introduced DW-480-0A, a fishing boat exclusively for nori cultivation, to help them deliver nori of the highest quality to customers.

Rich gifts from the Ariake Sea

The Ariake Sea receives nutrient-rich water from many rivers flowing into it, including the Chikugo and Yabe Rivers, which are Class A rivers in Kyushu. With a tidal range of up to approximately 6 m, the sea can provide the growing nori with lots of nutrients in the seawater and plenty of sunshine. Such an outstanding habitat environment in Saga makes the nori soft and richly flavored.

The harvesting season is approaching. First-harvest nori is especially soft and delicious, and is shipped as gift items. Since we heard that about 70% of nori from Saga is shipped as an ingredient for rice balls sold in convenience stores, we are glad whenever we see people in convenience stores buying these rice balls.

New reliable partner

Nori is raised from seed in oyster shells from spring onwards. Now it is autumn, and our full-scale work will start soon. We have set up poles in the sea and spread nets for nori cultivation, and we are now attaching seed to the nets. Although we start harvesting the nori later, after it has grown, we continue to work on the management and maintenance of nori without a day off from the start of the growing period until the harvest.

This is why we place great importance on the reliability of the boat. The DW-480-0A, which is our family's third boat for nori cultivation, sails stably and smoothly even on a windy day. The riding comfort is good and the boat is very reliable. A square bow (*) is used in the boat to increase the width of the bow deck. We can also set up poles with a greater sense of security, and we feel that it is easier to work on board the boat. It is also good that more materials and harvested nori can be loaded.

In addition to the improved operational efficiency, we also very much like the sharp bridge design.

(*) Original shape of popular front hull adopted in Yamaha's pleasure boats. The DW-480-0A is the first fishing boat that uses the shape. It also has the effect of reducing the amount of seawater flooding onto the deck.

To deliver nori to as many people as possible

Most of all, with the new boat we are motivated to work more than ever. While the work of nori cultivation is tough, we want as many people as possible to taste delicious nori from Saga and feel happy. It is the reward of our job and we are proud of it.


Fishing boat exclusively for nori cultivation, DW-480-0A
We developed the first fishing boat manufactured with FRP in 1965, and started mass production of large fishing boats equipped with diesel engines in 1970. They were fishing boats exclusively for nori cultivation, to be used in the Ariake Sea. The FRP nori cultivation boats became popular very quickly, and we have sold a total of 9,600 Yamaha fishing boats (DW series) for the nori cultivation market in the Ariake Sea. In June 2016, we released the new DW-480-0A, which features a stylish design aimed at next-generation fishery workers.

A Word from Yamaha Staff
We have further improved sailing stability and speed performance

In the Ariake Sea, which is proud to produce the largest yield of nori in Japan, the peak harvest season comes in the middle of the winter. We developed the next-generation fishing boat, DW-480-0A, targeting this market which has many young successors in their 20s. With outstanding sailing stability, stylish shape and further improved speed performance, the boats contribute to the revitalization of the market of nori production from the Ariake Sea, continuing to do great work at sea.
