Aoi Ward is one of the administrative districts of Shizuoka City, which was established on April 1, 2005, and boasts the largest area in Japan as an ordinance-designated city.
The area is the former Shizuoka city area before the merger with the former Shimizu city on April 1, 2003, excluding the former Nagata village area from the north of the Tokaido main line. It is the largest administrative district in Japan as an ordinance-designated city. This is because it has the former Abe District (area 849.36km2) in the mountainous area, which occupies more than 80% of Aoi Ward and about 60% of the total area of Shizuoka City, and the lowlands and flatlands that are easy to use as an urban area are extremely narrow. .. It also has the highest point in Shizuoka City (Mt. Aino, altitude 3,189.5m).
Most of the population of Aoi Ward is concentrated in the narrow plains in the southern part of the ward, and together with Suruga Ward, it forms the central city area of Shizuoka City. As the political and economic center of Shizuoka Prefecture, there are the Shizuoka Prefectural Office, which has strong earthquake countermeasures, the joint government building of the Shizuoka Prefectural Police Headquarters, and the branches of each city bank. The southern part has been the center of the Suruga region since the Imagawa period during the Warring States period. rice field. The town division, which was neatly divided on all sides of the southwestern side of Sunpu Castle, which functioned as the de facto sub-city of the Tokugawa administration, is almost the same as that of Ieyasu at that time.
The northern part of the ward is lined with mountains in the Southern Alps and has a small population. Hot springs are scattered in the valley and attract tourists. There is a branch office of the ward in the Ikawa area, but since the Oigawa Railway Ikawa Line runs in the direction of Kawanehoncho, the economic connection with the center of the ward is rather weak.
According to the Geospatial Information Authority of Japan's area survey by prefecture, city, ward, town, and village, the area of Aoi Ward is 1,073.75 square kilometers.
According to the Geographical Survey Institute, the north, south, east and west ends of Aoi Ward are located at the following positions. The eastern end is Yayoi Ryokuchi, the western end is about 1.5km south of Mt. Tekari near the head of Mt. In addition, the center of population based on the results of the 2010 census is near Oiwa 4-32.
Abe Oku / Ikawa
The former Abe Oku district (former Umegashima village, Okochi village, Tamakawa village. 45km from Shizuoka station to Umegashima), the former Kiyosawa village and former Okawa village upstream of the Yabushina river, and the former Ikawa village upstream of the Oi river are 1969. It merged with the former Shizuoka City on January 1, 2014.
With the transition of Shizuoka City to an ordinance-designated city on April 1, 2005, Abe Oku and Ikawa are included in Aoi Ward along with Shizuoka City. As for the administrative agency, Ikawa is treated as "Aoi Ward Office Ikawa Branch", and no administrative agency has been set up in the back of Abe. In Abe Oku and Oku Oi, small and long settlements are scattered along the river at low altitudes, and even the largest settlement, Ikawa Motomura, has a population of less than 500, so it is administrative in terms of cost. The reason is that it is difficult to set up an institution.
Ikawa is connected to Shimada and Kawanehon-cho by train, but it is often headed to the city center of Shizuoka City by local bus or passenger car. There are three prefectural roads leading to the city, but all of them are narrow as if weaving through the mountains, and because it is a long winding road that crosses the Fujimi Pass and Dainichi Pass at an altitude of over 1000 m, it takes 2 hours from Shizuoka City to Ikawa Dam. It will take a short time. In recent years, thanks to the construction of the Nagashima Dam, the prefectural road on the downstream side of the Oigawa River from Kanzo Station on the Oigawa Railway Ikawa Line has been very well maintained. It seems that it has increased slightly. Oigawa Railway Doi
