Kumamoto Castle
The town area of Kumamoto had been completed at the time of Katō Kiyomasa. Tsuboi Kawa (river) had been separated from the Shirakawa. Portions of Tsuboi Kawa and Iseri Kawa were made into moats of Kumamoto Castle. Samurai residential areas were placed around Kumamoto Castle, and the areas for townspeople were separated. Choroku Bridge was the only bridge crossing the Shirakawa (river); it was the only one for the defense of Kumamoto Castle. Suizenji Park, a Japanese style garden, was made for the exclusive use of the Hosokawa clan in 1634. A factory for wax production was completed in 1803; the products were transported over the rivers to the sea.
