Kōfu (甲府市, Kōfu-shi, Japanese: [ko̞ːɸɯᵝ]) is the capital city of Yamanashi Prefecture, Japan. The total area of the city is 212.41 square kilometres (82.01 sq mi).

Famous in the late 19th and early 20th centuries for "Japan-law" quartz twins. The name of this twin law is derived from this locality.

Kōfu 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 east–west axis. The city bisects the Kōfu Basin and is 250 to 300 meters above sea level. Kōfu is surrounded by mountains on all sides. Three quarters of Kōfu'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 Kōfu to the south.

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
