KÃ Âfu's name means "capital of Kai Province". During the Sengoku period, it was famous as the stronghold of Takeda Shingen.
Kà Âfu is located in north-central Yamanashi Prefecture which is in Central Honshu. It extends from the northern border of the prefecture with Nagano Prefecture to the south until it almost reaches the prefecture's southern border. It is narrow along its eastâÂÂwest axis. The city bisects the Kà Âfu Basin and is 250 to 300 meters above sea level. Kà Âfu is surrounded by mountains on all sides. Three quarters of Kà Âfu's territory is a part of Mount Kinpu in the north. Much of the northern portion of the city is within the Chichibu Tama Kai National Park. Mount Fuji is visible in the distance from Kà Âfu to the south.
KÃ Âfu has a humid subtropical climate (Cfa), though it is less wet than either the south or Sea of Japan coast due to its location in a shielded mountain valley. Temperature ranges are noticeably greater than in coastal regions: in 2004 KÃ Âfu reached a temperature of previously almost unknown in Japan, and it has fallen below as early as 26 October, which is about a month before the earliest freezing temperatures in such coastal cities as Kanazawa or Tokyo.
Per Japanese census data, the population of KÃ Âfu has remained relatively stable over the past 50 years.
Archaeologists have discovered evidence of human settlement in the KÃ Âfu area dating to the Japanese Paleolithic period, with continuous settlement through the JÃ Âmon, Yayoi and Kofun periods.
During the Nara period, the provincial temple of Kai Province was established in what is now KÃ Âfu, indicating that the Nara period provincial capital was located nearby, as the name of the city implies.
During the Heian period, a branch of the Minamoto clan, the "Kai-Genji" ruled over vast shà Âen estates, and developed a military force noted for its use of cavalry.
By the Muromachi period, a branch of the Kai-Genji, the Takeda clan came to dominate the area, and built a castle in what is now part of KÃ Âfu.
Under the rule of Takeda Nobutora, KÃ Âfu was rebuilt as a castle town starting in 1519, and remained the capital of the Takeda clan under Takeda Shingen and his son Takeda Katsuyori.
During the Edo period, Kai Province was tenryà  territory ruled directly by the Tokugawa shogunate, and Kà Âfu Castle remained its administrative center. In 1705, in a signal honour, it was conferred on Yanagisawa Yoshiyasu a favourite of the fifth shà Âgun. He was a member of the Yanagisawa clan descendants of the "Kai-Genji", the branch of the Minamoto clan which had been enfeoffed with the province of Kai in the eleventh century. His son, Yoshiyasu was transferred to Yamato-Koriyama Castle in 1724 after which Kofu Castle was again held directly by the Shogunate.
Following the Meiji restoration, with the establishment of the modern municipalities system, the town of KÃ Âfu was proclaimed on July 1, 1889.
The city experienced a major flood disaster in 1907 (æÂÂæ²»40å¹´ã®大水害) caused by heavy rain in a typhoon from the night of August 21, 1907 and by deforestation which was accelerated in Yamanashi Prefecture, due to the need for wood for fuel of the steam engines of the growing industrial policy of the Fujimura Prefectural Government. A police officer inspected the stricken area from August 23 to October 10, 1907. Patrol diaries of Masaki Tsukasa Kasaburo said "This heavy rainfall causes rivers to run down, landslides and levee failures, bridge piers destruction, etc., resulting in the destruction of homes and villages, village isolation, runoff, and traffic disruptions caused serious damage 233 people died, 5757 houses were run out, 650 hectares of lands have been buried or run down, 3353 landslides, collapse and damage distance of about 140 kilometers of levees, runoff and burial of roads, the damage distance was about 500 kilometers, 393 telephone poles collapsed.
