The purpose of this paper is to clarify the cement suppliers for each construction site during the interwar period when cement consumption increased in Japan. Specifically, the authors picked up and analyzed the cement suppliers at each construction site from the contents of the "Completion Reports", which are the construction records made by Shimizu-gumi during this period. There are 3,186 completion reports in total, of which 1,729 have a description of the cement supplier. These 1,792 cases are summarized in tables and figures by use, structure type, prefectures, year of construction, and total floor space. (See Table1-Table3, Fig.2-Fig.3) The findings are as follows: 1. The Cement suppliers can be classified into four types: "Manufacturing Companies", "Shimizu-gumi itself”,"Merchant" and "Supplied by Client". (See Table4) 2. By region, the percentage of “Shimizu-gumi itself” was high in the Kanto, and the percentage of “ManufacturingCompanies” was high in the Hokuriku. On the other hand, the percentage of “Merchant” was high in Chukyo, Osaka, and Kyushu. 3.By period , the percentage of “Merchants” has increased since the Ⅳ period (1936-) .(See Fig.5-Fig.9) 4. The percentage of “Manufacturing Companies” in each region was almost the same as the shipment percentageset by the regulation. (See Table6 and Table7) However, in the Chukyo, the number of cases of Mikawa, which is closely related to the Shimizu-gumi, was the highest. 5. Since the section handling cement was established at the head office, the cases of “Shimizu-gumi itself” were concentrated in the area under the jurisdiction of the head office, especially in Tokyo. 6. Looking at the breakdown of “Merchants” by region, there are some “Merchants” who have a lot of trades, but since there are many cases of "Others", it is indicated that there were trades with various “Merchants”. (See Table8) 7. Looking at the breakdown of “Supplied by Client", there were almost the same number of governments works and private works, and there were many cases of civil works and industry (See Table9). And there were many cases before 1930, when cement sales control began. (See Table9)
