1 Introduction

Purchasing style of Japanese consumers have made their own development. Purchase of goods with a large amount once a month or once a few weeks is a kind of global standard. On the contrary, purchase of goods with a small amount once in couple of days is common in purchasing style of Japanese consumers. Purchase of goods with a large amount in a weekend is recently getting to increase however, the interval is a week at the longest.

As a background, there are a variety of factors. Firstly, it can be mentioned that motorization in Japan has not developed as Europe and America. Therefore, it is difficult to buy goods with a large amount. Secondly, it can be mentioned that Japanese residence is narrow. Japanese residence is narrower than Western residence. Residence in downtown is narrow in particularly. Therefore, even if it’s bought in large quantities, there is no place to keep. Thirdly, it can be mentioned that Japanese seek a fresh. Japanese tend to buy a fresh thing. Culture to eat raw fish, such as represented in sushi is its symbol. Therefore, in order to get fresh things, it is to the frequent shopping.

Retailing of Japan has various features to accommodate Japanese purchasing. According to L.P. Bucklin, it shows the four factors as distribution results that consumer seek: spatial convenience, lot size, delivery time and width and depth of assortment. In four factors of L.P. Bucklin, purchase of goods with a small amount once in couple of days has strongly demanded spatial convenience and lot size. As a result, retailings of Japan are improved spatial convenience to make small scale store in comparison with Europe and American. Also, lot size is smaller than Europe and American. Furthermore Japanese tendency to want to select products in comparison from the instruments that number also strong. Distribution style of Japan is making small scale store and preparing small lot of goods widely. Compared with store of Europe and American are located in the extensive sites on the suburbs and assorted at large lot of goods, it is inefficient. In order to perform efficient management, retailing is common to become large scale by M&A. As a result, Market becomes oligopoly. And leading market share increases. In actuality, in Australia, top five companies account for about 90 % of the market. Also, in America, top eight companies account for about 40 % of the market. On the contrary, in Japan, top five companies account only 7 % on the market. As a background, it was born to various operating styles to accommodate spatial convenience. Specifically, there is convenience store with improved temporal convenience by being open 24 h. Also, it is a factor that the government had been factor also had been protecting a small retailing to restrict the opening of large-scale stores by legal regulations. However, in recent years, these legal regulations have been abolished one after another by the deregulation. As a result of, case to overlap with each of management style has increased because retailing pursues the convenience. Specifically, convenience store is sold fresh food and supermarket is extended the operating hours. Therefore, market of retailing has become highly competitive. In addition, growth of online market is also more vigorously competition in recent years. Under such fierce competition, the retailing has been introduced a membership system in order to survive. The purpose of membership system is to enclose the customer by member benefits, such as coupon. However, if a membership benefit is functioning effectively, membership system is meaningless.

The purpose of the research is to discover more effective method of membership system by analyzing the actual data.
