In April 2008, Japan’s Food Safety Commission (FSC) was asked by the Ministry of Health, Welfare and Labour to make an assessment of the safety of food from cloned animals. Somatic cell cloning has recently emerged as an issue also in Japan, and on February 29, 2009, a special assessment group on cloned animals set up in the FSC’s Expert Committee announced that such food was safe.

On March 24, 2009, the Food Safety Commission once more discussed this topic. However, it became clear that there were a number of unresolved issues and serious problems related to this technology. CUJ raised several questions at this meeting. We were told that in Japan, some 1,240,000 cows are slaughtered annually, and among them approximately 720,000 have some defects or show symptoms of disease. The officials reluctantly admitted that in such cases, the lesions or sick parts are simply removed, and the rest of the carcass is used for food. Clearly, we must assume that the same practice will continue also in the case of sick cloned animals. More »

Rainy season has just begun and we got some torrential downpours, but today is sunny and humid in Tokyo. We are pleased to publish two more presentations from last year’s World Foodless Day, with a focus on food prices and how to improve Japan’s low food self-sufficiency rate.

Due to the many graphs and tables, we are publishing both a low-graphics version and a full graphic version this time. Please download the pdf file of your choice. - Editors More »

A quantitative analysis based on the Food Demand-Supply Table, the Guideline of Nutritional Requirement for the Japanese people, and the Local Production-Local Consumption principle

Paper presented at the World Foodless Day in Tokyo, October 16, 2008

The current world-wide food crisis has made it clear that the low Japanese food self-sufficiency ratio is the underlying cause of various food-related problems. As one of the fundamentals for our survival, food is more and more dependent on foreign political and commercial trends that are beyond our control. Also Japan hunting for food in other countries contributes to the tension on world food trade markets and tends to raise international food prices. Japan’s food mileage, the world’s highest, reaching 910 billion ton-km in total, and 7,110 ton-km/capita annually [1], is adding a large amount of CO2 into the global atmosphere. This paper looks at ways to improve Japan’s food self-sufficiency from the consumer perspective.

Demand-side Approach

Motivated by a number of concerns, we attempted a quantitative analysis on to what level Japan’s food self-sufficiency could recover. For this purpose, we used a static model based on the Food Demand-Supply Table (a statistic published by the Ministry of Agriculture, Forestry and Fishery), the Guideline of Nutritional Requirement for the Japanese (published by the Ministry of Health, Welfare and Labour), and the Local Production-Local Consumption principle.

Japan’s food self-sufficiency ratio is estimated to be around 40% in 2007. Several estimates of Japan’s potential food self-sufficiency have already been made, but in general, they have focused mainly on the supply-side, assuming selectively that the demand-side of food remains out of the policy scope. However, one of the main factors causing our low food self-sufficiency can be attributed to the over-consumption of meat and fat, items that are unsuitable for the Japanese farming conditions [2].

That is why we asked, “What if the Japanese dietary habit changed to one more healthy and more suitable for domestic production?” To do this, we decided to create a model on the basis of the demand-side approach, starting with our food consumption patterns, followed by the domestic food production efforts adapted to these patterns.

Three Patterns of Food Consumption

The first food consumption pattern we took as a model is a set of food intake and nutritional data recommended by the Ministry of Health, Welfare and Labour. This pattern has been created as the ideal for Japanese people to maintain their health, avoiding lifestyle-related sickness (MHWL pattern). The second pattern is a set of food requirements based on the daily meal menus organised specifically for our model by Setsuko Shirone, an expert of sustainable food consumption and organic agriculture. Let us call this Chisan-chisho pattern (LP-LC pattern), after a popular movement that encourages local production and local consumption in Japan.

Figure-1 shows the differences of the consumption of each food-group or item per day per person compared with the status quo (as of 2005). According to the MHWL pattern, the ingestion of grains, potatoes and vegetables would increase, while consumption of meat, milk products, sugar and fat would drastically decrease. Turning our attention to the LP-LC pattern, we note that this tendency is even more radical. The exception is the high amount of marine products intake that is still considered to be possible; all of this, however, consists of small fish and coastal fish, as well as continued consumption of other domestically available marine species.
