Hanroku Yamaguchi's "Plan for Osaka" is known to be a pioneering example of Japanese city planning. This is the third in a series of papers confirming the contents of the accompanying text to Yamaguchi's plan, "Explanation of the Plan for Osaka". Part three deals the design of the lot number and alley that Yamaguchi added to the plan. Yamaguchi proposed the design in two ways: one is to set general principles, and the other is to deal with specific cases in light of individual conditions. The combination of concreteness and future vision is the most significant aspect of Yamaguchi's plan.

Hanroku Yamaguchi's "Plan for Osaka" is known to be a pioneering example of Japanese planning. This is the second in a series of papers confirming the contents of the accompanying text to Yamaguchi's plan, "Explanation of the Plan for Osaka". Part two deals Yamaguchi's plan for the watercourse, park, harbor railroad station and an alternative plan for the main (first class) street. We point out that the watercourse plan typically reflects Yamaguchi's concept of industrial development, and plans for the harbor railroad station and street alteration show a tight connection between Yamaguchi's plan and the Osaka Harbor Construction Plan.

This study examined the impact of "Plan for Osaka, 1899" by Hanroku Yamaguchi on the urbanization of the Osaka port reclaimed area.1. We confirmed certain influences of the design standards shown in Yamaguchi's "Explanation" on the development plan of the reclaimed area, especially on the house numbering and size adjusting methods of town blocks and plots.2. Yamaguchi's standards for 'backstreet and alleys' have also affected the urbanization process. Such standards prepared to adapt to specific conditions and variations worked in practice.3. The "Plan for Osaka, 1899" had an impact on actual urbanization with detailed design.
