Torotuna/shirotuna, produced in Shizuoka Prefecture: protecting the ‘delicious cycle of Shizuoka’.

The blue-colored torotuna is a high-quality canned tuna exclusively from the belly of the yellowfin tuna. It is recommended to pair it with pasta, rice, or enjoy as a snack.

Shirotuna is a flake-type canned tuna made from albacore tuna that goes well with salads and mayonnaise.

From a first glance, it might look like ordinary canned tuna but actually this is where the ‘delicious cycle of Shizuoka’ starts.

99% of the canned tuna in Japan is produced in Shizuoka Prefecture. After the catch is offloaded in Shimizu Port in Shizuoka prefecture, it is moved to the processing factory in Shimizu. Instead of throwing away not suitable fish parts such as heads, tails and bones, workers transport it to the factory to dry and use as animal forage and fertilizer.

Shizuoka has been using the tuna fertilizer to grow delicious tea and oranges for a long time.

In recent years, the amount of canned tuna made in Shizuoka has been slowly decreasing due to high production costs and price competition. It negatively impacts other agricultural businesses putting the ‘delicious cycle’ in danger.

Torotuna and shirotuna were created to bring more sustainability into the ‘delicious cycle’ in Shizuoka. Hand-made in Shizuoka, these two products are famous for the unique taste and packaging. Help Shizuoka protect its ‘delicious cycle’ by purchasing it.

Growing nori seaweed protects marine ecosystem (Seto Inland Sea, off the coast of Kasaoka City, Okayama Prefecture)

Only a few farms in Japan produce a nori seaweed called genshisai. Nori is a dried seaweed, an indispensable ingredient in Japanese cuisine. Marine ecosystem plays an important role in producing delicious seaweed but due to the recent changes it is getting more and more difficult to grow seaweed. One of the essential reasons is that the nutrients such as nitrogen, phosphorus and silicon disrupt the delicate balance in marine systems. Extra nutrients can stimulate the excessive growth of plankton and cause a red tide outbreak. On the other hand, low levels of nutrients prevent nori seaweed from growing, negatively affecting marine ecosystems.

There are other problems such as global warming and changes in the river flow. Seaweed plays an essential role in building the marine food chain.Genshisai is a seaweed cultivated in the Seto Inland Sea off the coast of Kasama city, Okayama prefecture. Don’t miss this product that has been contributing to the development of the marine ecosystem for more than 10 years.
