Ōtsu (大津市, Ōtsu-shi) is the capital city of Shiga Prefecture, Japan. As of 1 October 2021^[update], the city had an estimated population of 343,991 in 153,458 households and a population density of 740 persons per km².^[1] The total area of the city is 464.51 square kilometres (179.35 sq mi).

Ōtsu is part of ancient Ōmi Province and has been settled since at least the Yayoi period. It was an important center of inland water transportation on Lake Biwa and was referred to in the Man'yōshū as Shiga no Ōwada (志賀の大わだ) and Shigatsu (志賀津).^[2] It was also on the main land routes, the Tōkaidō and the Nakasendō connecting the eastern provinces with the ancient capitals of Japan.^[3][4] Additionally, the ancient Hokurikudō, which connected Kyoto to the provinces of northern Honshu, ran through Ōtsu.^[4] From 667 to 672, the Ōmi Ōtsu Palace was founded by Emperor Tenji was the capital of Japan.^[3] Following the Jinshin War Ōtsu was renamed Furutsu (古津, "old port").^[2] A new capital, Heian-kyō, (now Kyoto), was established in the immediate neighborhood in 794, and Ōtsu (meaning "big port") was revived as an important traffic point and satellite town of the capital. With the establishment of the new capital, the name of the city was restored to "Ōtsu".^[5][2]

Ōtsu prospered during the Edo period because of its port on Lake Biwa and as Ōtsu-juku, a major shukuba on the Tōkaidō and Nakasendō highways. The city was under direct administration of the Tokugawa shogunate, both for its strategic location and for its role as a center of travel and trade.^[4] Zeze Domain was based in Zeze, a neighboring castle town, and the smaller Katada Domain occupied the northern area of the present-day city from 1698 to 1826.^[6][7]

The Meiji Restoration of 1868 saw the establishment of a new central government in Tokyo and the abolition of the han system. Numerous prefectures under control of the Meiji government were created, and part of the old province of Ōmi was designated as Ōtsu Prefecture in 1868. Several smaller prefectures were merged into Ōtsu Prefecture in 1871, which became part of present-day Shiga Prefecture on January 1, 1872. Ōtsu was named the prefectural capital of Shiga.^[8][9] The town of Ōtsu was established on 1 April 1889 with the creation of the modern municipalities system. It was raised to city status on 1 October 1898.

The Ōtsu incident, a failed assassination attempt on Tsarevich Nicholas Alexandrovich of Russia (1868 – 1918, later Tsar Nicholas II), occurred on 11 May 1891. Nicholas, returning to Kyoto after a day trip to Lake Biwa, was attacked with a saber by Tsuda Sanzō (1855 – 1891), an escort policeman. Nicholas survived the assassination attempt, but the incident was seen as a crisis in Japanese-Russian relations.^[10][11] For a while the local populace considered renaming the city to avoid the stigma associated with the scandal, but the idea was eventually shelved.

The Lake Biwa Canal (8.7 kilometres (5.4 mi)) was constructed in the 1890s between Ōtsu and Kyoto. The canal, which was later expanded during the Taishō period, played an important role in connecting the cities, facilitating water and passenger transportation, and providing electrical energy to power Japan's first streetcar railroad services. The canal was designated a Historic Site in 1996.^[12][13]

The city area gradually expanded by annexation of the village of Shiga in 1932, towns of Zeze and Ishiyama in 1933, villages of Sakamoto, Ogoto, Sakashita-honmachi, Oishi and Shimoda-kamimura in 1951, and towns of Katata and Seta in 1967. On March 20, 2006, the town of Shiga (from Shiga District) ceased to exist after merging into Ōtsu.^[4]

Per Japanese census data,^[14] the population of Ōtsu has grown steadily over the past century.

Ōtsu is located on the southern and western shore of Lake Biwa and occupies most of the southwestern portion of Shiga Prefecture.^[5] The city is L-shaped and stretches along the southwest shore of Lake Biwa, Japan's largest lake.^[4] Ōtsu ranges from the densely populated alluvium depressions near the shore of Lake Biwa to sparsely populated hilly and mountainous areas to the west (Hira Mountains and Mount Hiei) and south of the city.^[5] Mount Hiei to the west encompasses much of the border of the city and Shiga Prefecture with Kyoto.

Lake Biwa provides water for the industrial areas of the Kansai Region, irrigation and drinking water in the Shiga area.

The Eight Views of Ōmi refer to a series of scenic views of Ōmi Province, the present-day Shiga Prefecture. The eight views were chosen in 1500 by a court noble and poet of the Muromachi period, Konoe Masaie (1444 – 1505). The views were inspired by the Eight Views of Xiaoxiang, China, and are located at the southern end of Lake Biwa. Six of the sites are within the city of Ōtsu, and two are located just beyond the borders of the city. The sights were depicted by Hiroshige (1797 – 1858) in several different series of ukiyo-e pictures, and served as an inspiration for other artists and literary figures.^[50][51]

The Ōtsu Matsuri is the largest festival in the city. It begins Saturday, October 6 and ends on Sunday, October 7 and is connected to the Tenson Shrine in the Kyō-machi district of the city. The Ōtsu Matsuri is similar to the Gion Matsuri in Kyoto, and features thirteen tall lantern floats, which resemble those of the Gion. The floats feature karakuri ningyō, or mechanical dolls which operate via special mechanisms.^[52] The thirteen floats each have their own tradition, customs, and lineage, and are paraded through the city from 9:30 am until 5 pm on the day of the festival.^[53] The Ōtsu Matsuri is thought to have begun in the early Edo period, and the first written record of the festival dates to 1624. Many of the hikiyama in use today date from the Edo period, and are accompanied by matsuri-bayashi festival music unique to the city.^[52] The Ōtsu Matsuri is designated a Prefectural Intangible Folk Treasure by Shiga Prefecture.^[54]
