A Business Historical Research on the Innovation by Distributors in Soap, Detergent and Toiletries Industry from the mid-1970s to 1980s in Japan

这项研究回顾了日本两家领先的批发公司，并展示了制造商的独家批发公司和一般批发商之间的关系是如何在日本形成的。它首先讨论了关东地区、北海道和东北地区的Kao独家批发销售公司的历史。然后研究了北海道当地领先的批发公司Daika的案例，该公司将业务活动扩展到东北和关东地区。通过观察这两家公司，我可以理解日本制造商的独家批发公司和一般批发商之间的竞争与合作关系是如何形成的。

This study reviews two leading wholesale companies in Japan and shows how relationships between manufacturers' exclusive wholesale companies and general wholesalers were formed in Japan. It first discusses the history of Kao exclusive wholesale sales companies in the Kanto region and in the Hokkaido and Tohoku regions. It then looks at the case of Daika, a leading local wholesale company in Hokkaido, which expanded its business activities into the Tohoku and Kanto areas. By looking at these two companies, I can understand how the competitive and cooperative relationships between manufacturers' exclusive wholesale companies and general wholesalers were formed in Japan.
