Transformation during the construction of Lake Biwa Canal 5: Urban Development Influenced by the Canal
This section explaining the nearby urban development related to the Canal.
5.1 Okazaki Area: Created a large and rich waterfront surface
The final LBC plan attempted to reduce the travel time for shipping by adopting technology such as locks. After the adoption of incline railway system in 1887, the Outo Canal was planned to run straight west from the end of the incline as shown in the following figures.

Besides the route of directly go straight toward west, there is an alternative route which took the shortest slant route proposed by the manager of the LBC, Noriyoshi Sakamaoto in 1888. However, Mr. Kitagaki rejected the slant route plan and he said in the conference “In the future, we think Okazaki district will experience urban development. And the slant route didn’t suit the master plan of city because it created a triangle site.”
Later on, Dr. Tanabe said that “Kyoto didn’t have a large water surface. So, if the Outo Canal had a 36 meters channel, it would become a rich waterfront place for citizens.” Therefore, Outo Canal, which was designed for shipping in an urban area produced a rich waterfront area. In the end, this area was used for boating and played an essential role in the fourth exposition of domestic industry in 1895.
5.2 Along the Canal Branch: enhanced neighborhood quality of life
The final route of the LBC is divided into a main shipping channel and a branch of irrigation and water mills.After 1889, hydroelectric power replaced the need for water mills, and the canal branch functions was strictly focused on irrigation. Therefore, the branch of LBC becomes the human-scale flow, which is different from other channels of LBC. This branch is used for irrigation, and for fire prevention in the gardens of houses and temples near Higashiyama mountain. The branch of LBC improves the quality of life of nearby residents because the waterway is no longer used for shipping or to producing hydropower.
