Kinki University successfully completes eel farming

Kinki University has succeeded in completely cultivating edible eel. Previously, I was surprised to hear that eels had been successfully hatched artificially, but this time it will be completely farmed. The ecology of eels is not well known, and it was thought that eel fry hatched in the Philippines or near China, grew up, and circulated throughout the Japanese archipelago, but eels are now being farmed within Japan, including these areas.
Originally, eel was a delicate species that reproduced through wide-area circulation, and was rare and expensive, but due to the cost of aquaculture, it may soon become a food that can be easily eaten. What is noteworthy is the eel protein. Eel has more protein per 100g than beef.

The Japanese archipelago is poor in protein sources.

Originally, there were no large animals living in Japan, so people ingested protein from tofu, miso, and fish. Whaling was largely a cultural aspect and was a source of food for large animals and high protein content. If it were possible to farm eel in large quantities, it would be more efficient than other edible meats, and the result would be omega-3 fat, which is good for the body instead of animal fat.
Japan's food self-sufficiency rate is announced to be 66% on a monetary basis, but the low level of 38% on a calorie basis is largely due to protein deficiency. If edible eel were easily available on the table, the calorie self-sufficiency rate would rise dramatically.

World's largest rare earth mining

Recently, it was announced that rare earth mining will begin in 2024 in the deep sea of Minamitorishima, Japan's Ogasawara Islands. The amount of rare earths buried in this sea area is said to be the largest in the world, and is said to be enough to meet the entire world's demand for several hundred years. The underground oil reserves of the Ibaraki Prefecture Goura coast are estimated to be one of the largest in the world, based on the amount and area of gas generated on the seabed surface.

Possibility of world's largest oil field

Japan has not made any progress in marine resource development. Despite the fact that there was a lack of resources as a reflection of the defeat in the war, Japan continued to engage in resource diplomacy by relying on foreign sources, and these became a conduit to oil-producing and other resource-rich countries. However, when the world becomes this unstable, it is impossible to say such things.

Japan has the 6th largest area in the world, including the EEZ.
