Abstract
On October 6, 2015, TPP (Trans-Pacific Strategic Economic Partnership Agreement) has reached a basic agreement. TPP benefit in the industrial sector of Japan. However Japanese are wary about agriculture sector. As mountains account for 80 % of country, it cannot be efficient agriculture on a large scale in Japan. It is disadvantageous in the price side too. Furthermore, it becomes the problem that the area under tillage decreases by the aging of the scholar of agriculture. Among in this environment, the freshness vegetables are indispensable to a domestic dining table every day. Therefore, it is necessary that the freshness vegetables are supplied qualitative, price mark and quantitatively. It is the purpose that changes in the price of fresh vegetables is to analyze whether give how to affect the purchasing behavior of consumers.
As the analysis, changes in price and quantity were classified into three features.
Feature 1 is “two peaks of quantity”. Feature 2 is “The difference in the Hall vegetables and cut vegetables”. Feature 3 is “The difference in the way of price declines”.
From the analysis, the authors clarified what kind of influence the change of the price of freshness vegetables had on the purchasing action of consumers. In addition, it was found that there is a difference market transaction price and store price.

1 Introduction
1.1 About TPP
On October 6, 2015, TPP (Trans-Pacific Strategic Economic Partnership Agreement) has reached a basic agreement. TPP is diversified economic partnership agreement with the aim of liberalization of the economy by the countries of the Trans-Pacific. TPP was started in among Singapore, Brunei, Chile, and New Zealand on June 3, 2005. After that, due to an increase in participating countries, it has joined 12 countries. In addition to this, it is said that Korea and China and Thailand and Taiwan show interest (Fig. 1).
1.2 Trends in Japan’s Agriculture
Approximately 80 % of Japan are mountainous districts. This is attributed that Japan belongs to the Ring of Fire. Therefore, it is difficult for farmer to secure large-scale farmland. Table 1 shows area per farmer review. Farmland area of Japan is about one two-thousandth as small as that of Australia which is a big exporter of farm produce. Being narrow farmland area per one farmhouse is reduced farm production efficiency. Therefore, farm production price of Japan is higher than Australia’s it.
In addition, it is for farmers of Japan to be aging and decrease. Figure 2 shows the configuration of the age agriculture employment population. Percentage in this figure shows composition ratio each year and Ave. in figure shows average of age of famers each year. It shows that agriculture employment population in 2015 is less than half compared to that in 1995 and Average age goes on increasing year after year. In particular, the proportion of the agriculture employment population of over 65 years old in 2015 is 63.5 %, and average age in 2015 is 66.3 years old; it is very high.
As a background, there is two reasons that it is policy of the Japanese government and low wages of farmer. About first reason, it has been promoted the policy of reducing crop acreage by Japanese government. Japanese major production of agriculture is rice. However, Japanese no longer eats rice by westernizing of eating habits compared to before. For this reason, Japanese government has kept product prices by promoted the policy of reducing crop acreage. For this reason, Japanese government has kept product prices by promoted the policy of reducing crop acreage. At the same time, Japanese government has protected farmers by imposing duties from foreign countries. About second reason, as mentioned previously, there is inefficient farm production. Also, it is thought that the primary industries such as the agriculture and forestry marine products industry continue declining in the country which is high in wages like Japan widely. Furthermore, it is one of the reasons that there is a uniquely Japanese distribution system of production of agriculture. That system is commonly to be through JA (Japan Agricultural Cooperatives). At first, JA was made in order to protect farmers. It was purpose of JA to stabilize shipping prices by shipping together the products. However, in the case of system of JA had to ship all products of making. Therefore, even if farmers thought to want to sell by myself a part of products of making, they weren’t able to do it. This means that famers can’t decide product prices himself. Accordingly, in recent years, it has become the problem regarding system of JA.
1.3 Trends of Vegetable’s Price in Japan
Vegetable’s price in Japan is varies greatly. As a background, there is for seasons in Japan. There are the four seasons, and the severe change of the climate is not stable in its production of vegetables. Therefore, vegetable’s price is not stable too. Figure 3 shows market transaction price of vegetables in Tokyo. The vertical line in Fig. 3 shows percentage of increase or decrease of the quantity standard of July 1, 2013. The price of vegetables, as can be seen from this figure change up to twice.
1.4 The Effect of TPP Gives to Japan
As mentioned previously, Japanese agriculture is having various problems. Therefore, it was divided Japan whether she will join or not to TPP. Especially, agricultural group including JA declared opposite opinion. On the other hand, TPP brings profit to manufacturing industry by being rescinded tariff of shipping country. Especially, it has brought about great effect for Japan which exports a lot of industrial products. Finally, Japanese government declared to join TPP on the condition that protect of rice, wheat, dairy products, beef, pork, sugar cane 5 items.
2 Data Used for the Analysis
The analysis was carried out using the purchasing data was offered from All Japan Foods Co., Ltd. which be supplied by Joint Association Study Group of Management Science of all customers who visited stores.
2.1 Store Data Used for the Analysis
It is used 5 stores in Hokkaido area and Tokyo area respectively to analysis. Data of store shows in Table 2.
Figure 4 shows position in Area of Hokkaido and Kanto. Area of Hokkaido is located in the north of Japan. Public transportation of Hokkaido is not much development. Therefore, motorized society is developing into Hokkaido in Japan relatively. On the contrary, public transportation of Tokyo is highly developed to be the center of Japan. Therefore, there are a lot of people who don’t have a car.
Also, it is found that shop area is proportional to the daily turnover.
2.2 Purchasing Data of All Customers
It is indicated below about the outline of data.
Term: Jul. 2013–Jun. 2014
Area: Hokkaido area and Tokyo area, 5 each
Number of data: about 18.6 million cases
Data is receipt data. Including information is sale date, sale time, membership number (members only), large classification code, middle classification code, jan-code, using coupon flag (members only), and coupon number (members only).
3 Procedure of Analysis
3.1 The Selection of Kind of Vegetables for Analysis
Firstly, the authors selected vegetables for analysis. As research object, it is targeted the 14 items listed in “About the growth situation and price outlook of vegetables” that are announced every month by Ministry of Agriculture, Forestry and Fisheries. These 14 items are popular items and are eaten in Japan. Table 3 shows vegetables which is selected for analysis.
3.2 The Selection of Kind of Items for Analysis
Secondly, the authors selected items for analysis. As a reference Jan-code, it targeted things that are sold more than 250 days corresponds to two-thirds of the year were included. Table 4 shows items that are selected for analysis. Looking at the figure, there is “1/2 off”, “1/4 off” or “1 pice” in item name. This shows purchasing style of Japanese. The Japanese tends to purchase it many times little by little. Therefore, supermarket in Japan sells the item which was subdivided. Additionally, about Taro, it was excluded from items for analysis because it didn’t exist items were sold more than 250 days.
3.3 Ranking for Items Price
Thirdly, the authors was the ranking of the items price. At first, we seek Dairy price each item. If same item sells at plurality of stores in same day, daily price was the average of the price of each store. Next, it was classified as a price per day the 22 stage from less than 100 yen to more than 300 yen as shown in Table 5. Finally, we aggregated number of sales each rank.
4 Result of Analysis
As the result of analysis, it was found three characteristics.
4.1 Characteristic 1: There Was Two Peaks
The first characteristic, it was found two peaks in low-price rank. As the background, there is sale of supermarket. It is commonly that the supermarket in Japan performs a sale in once a week. Thereby, vegetables also are often on sales items. Therefore, these two peaks is conceivable that one is normal selling price and the other is sale selling price. Figure 5 shows Specific examples that belong to characteristic 1.
4.2 Characteristic 2: Difference of Hole Vegetables and Cut Vegetables
The second characteristic, it was found difference of hole vegetables and cut vegetables. Hole vegetables sales volume is greatly changed with the rise of the price. Reduces the quantity and price of the hole vegetables increases. The quantity of cut vegetables rises. This tings is conceivable that there have been switching to cut vegetables from the Hall vegetables with an increase in price. Figure 6 shows Specific examples that belong to characteristic 2. Market price shows market transaction price in Tokyo, and its unit is “Yen”. Otherwise shows percentage of increase or decrease of the quantity standard of July 1, 2013.
4.3 Characteristic 3: Difference of Way of Decline in the Items Price
The third characteristic, it was found difference of way of decline in the items price. Even if these products are the same products, the change of the price is not similar. For the reason, it is conceivable difference of sales specifications. Figure 7 shows Specific examples that belong to characteristic 3.
5 Conclusion
5.1 Conclusion
The authors analyzed changes in sales volume with respect to a change in price using purchasing data of all customers. The purpose of the analysis was to clarify effect of changes in fresh vegetables prices give consumers.
As a result of the analysis, it was clarified that the change in the price of fresh vegetables had three features.
The result of the study is able to predict the influence that the change of the price of vegetables gives demand. By using this prediction, the farmers can be maintained prices by exported overseas, when the supply is too large relative to demand. As mentioned previously, farmers of Japan has disagreed to TPP. However, the famers can utilize TPP in what they export abroad positively in this way effectively.
5.2 Further Task
As a result of the analysis, it was clarified that the change in the price of fresh vegetables had three features. However, using the analysis as for the data which I used for analysis this time, standard information suffered a loss. Therefore, it is necessary to analyze considering standard information. Also, because there is season in vegetables, a price fluctuates by a season. It is necessary to analyze considering seasons too.
