Okazaki area, east of Kyoto city, was built as an important noble and religious place in the Heianperiod (794-1185). We supposed that at the end of the 16th century there would be settlementsenclosed by fossa similar to landscapes represented in Rakuchu Rakugai-zu, a series of paintings ofKyoto by local artists, which is one of the most important urban iconographies of Japan. In the Edoperiod (1603-1867) Okazaki area assumed the role of suburban agricultural zone which provided thefood production to the urban habitants. It also could be the place of scenic beauty in which theintellectuals commonly lived there. But after the Meiji Restoration, the role of Okazaki area changedcompletely. In 1885, Kyoto prefecture started the great public canalization project as the water supplybetween Kyoto and Otsu of Shiga prefecture. Kyoto prefecture also planed the industrial districtconstruction in Okazaki area. In 1895 pavilion buildings were built for the 4th Inner NationalExhibition of Japan and at the same time Heian-Jingū Shrine was constructed for the millenniumceremony for foundation of Kyoto city. After that the territory prepared for the exhibition was reusedfor the cultural district. The cottage area of bourgeois and politicians was created at the eastern part ofOkazaki area. The canal project accompanied the electric generation plant. Okazaki area became thesymbol of the modernization of Kyoto city.
