1 Introduction

Wedding market in Japan is about 3 trillion yen [1] conjunction with marriage costs and new life preparation costs, and the number of marriage couples is estimated to be approximately 650,000 pairs [2]. Domestic population is in the medium- and middle-long term downwards due to the declining birth rate. It has been presumed that there is also decreasing number of marriages, compare to this number, the implementation rate of the wedding reception is about 50 % [3]. It can be recognized as the wedding market still has a certain amount of potential market. Against a backdrop of this, it is essentially to be impressed the “customer”, satisfied more than what they expected. Far beyond that, the most important fact is made them influencers to dig up more potential customers. The marketing researches market of interest has been changed in 2 decades from spending on the expenditure non-durable goods such as food in everyday of life to the services in providing. This means that consumer spends more on “buy goods” to “usage of the service” [4]. Wedding reception is not only goods itself, because it is the market that is selling the services too, and to survey on the CS (Customer Satisfaction) through survey after the enforcement wedding reception is estimated to be higher. Also, especially in the marketing mix, it is said to be important part that is post Encounter marketing mix (after customers received the service) [5, 6], what products and services to customers is to contribute to the overall CS improvement attention is focused, and decided to research.

Index that becomes the axis in this study is the NPS (Net Promoter Score). This is an indication of the investigation method for measuring customer’s loyalty proposed by Frederick F. Reichheld. To classify into 3 groups by scores (the range of 0–10) through questions the possibility of recommendation the company (products, services or brands) to friends or colleagues along with the answer.
