# Shinano Province

Shinano Province (信濃国, Shinano no kuni) or Shinshū (信州) is an old province of Japan that is now Nagano Prefecture.
Shinano bordered Echigo, Etchū, Hida, Kai, Kōzuke, Mikawa, Mino, Musashi, Suruga, and Tōtōmi Provinces. The ancient capital was located near modern-day Matsumoto, which became an important city of the province.
The World War II-era Japanese aircraft carrier Shinano was named after this old province.

## Historical record

In 713, the road that traverses Mino and Shinano provinces was widened to accommodate increasing numbers of travelers through the Kiso District of modern Nagano Prefecture.
In the Sengoku period, Shinano Province was often split among fiefs and castle towns developed, including Komoro, Ina, and Ueda. Shinano was one of the major centers of Takeda Shingen's power during his wars with Uesugi Kenshin and others.
During the Azuchi–Momoyama period, after Nobunaga's assassination at Honnō-ji Incident, the province was contested between Tokugawa Ieyasu and the Go-Hōjō clan based in Odawara castle. The Tokugawa clan, The Uesugi clan and the Hōjō clan each aspired to seize the vast area in Shinano Province, Ueno region, and Kai Province, which ruled by the remnants of the many small clans formerly serving the Takeda clan. Following of disorder post death of Nobunaga, at the same time with Ieyasu departure an army of 8,000 soldiers to those disputed region. This caused the triangle conflict between those three factions in the event which dubbed by historians as Tenshō-Jingo War broke out. As the war turned in favor of Tokugawa clan, combined with the defection of Sanada Masayuki to the Tokugawa faction, the Hōjō clan now negotiate truce with Ieyasu and The Go-Hōjō clan then sent Hōjō Ujinobu as representative, while the Tokugawa sent Ii Naomasa as representative for the preliminary meetings. Furthermore, In October, representatives from the Oda clan such as Oda Nobukatsu, Oda Nobutaka, and Toyotomi mediated the negotiation until the truce officially concluded.
Suwa taisha was designated as the chief Shinto shrine (ichinomiya) for the province.
In 1871, during the Meiji period, with the abolition of the han system and the establishment of prefectures (Haihan Chiken) after the Meiji Restoration, Shinano Province's ex-domains/1871 prefectures and ex-shogunate territories/1868 prefectures (mainly Ina [merger of several shogunate demesne administrations with parts of Matsumoto], Okutono, Iwamurada, Komoro, Ueda, Matsushiro, Suzaka, Iiyama, Suwa/Takashima, Takatō, Iida, Matsumoto) and Takayama/Hida which covered Hida Province were administratively merged into Nagano (initially Nakano Prefecture in 1870) and Chikuma prefectures. The seat of the prefectural government of Nakano was Nakano town from Takai District (became Nakano City in 1954), Nagano's prefectural capital was Nagano town in Minochi District (→Nagano City in 1897), and Chikuma's capital was Matsumoto town, Chikuma district (Matsumoto City from 1907). In the second wave of prefectural mergers in 1875/76, Chikuma was split again: the Western part covering Hida Province was merged into Gifu, and the Eastern part in Shinano became part of Nagano. Since that time, Nagano is essentially contiguous to Shinano.
