Kōchi Prefecture comprises the southwestern part of the island of
Shikoku, facing the
Pacific Ocean. It is bordered by
Ehime to the north-west and
Tokushima to the north-east. It is the largest but least populous of Shikoku's four prefectures. Most of the province is mountainous, and in only a few areas such as around Kōchi and
Nakamura is there a coastal plain. Kōchi is famous for its many rivers.
Inamura-yama in Tosa-cho is the highest peak in Kōchi prefecture with an
altitude of 1,506 meters
above sea level. Kōchi Prefecture has the highest percentage of land covered in mountains out of all Japanese prefectures at 89% with the national average being 66%. The highest peak in Kōchi Prefecture is
Mt. Miune at 1,894 meters (the highest peak in Kōchi Prefecture is Tebakoyama at 1,806 meters). Due to its location in the Shimanto Group geological area, Kōchi Prefecture has many sedimentary rocks and is prone to landslides. Kōchi Prefecture has many rivers such as the
Shimanto River in the western part of the prefecture,
Niyodo River flowing from
Mount Ishizuchi into the
Tosa Bay, and
Yoshino River flowing into
Tokushima Prefecture. Historically, Kōchi Prefecture has not suffered from a lack of water, however
river management has been a consistent issue. In the early
Edo Period, samurai Nonaka Kenzan oversaw large scale improvements to the
Tosa Domain's major rivers. Modern Kōchi Prefecture is known for its river management and minimal water damage despite receiving a large amount of rainfall. The
Kuroshio Current flows by Kōchi Prefecture's coast. The climate of Kōchi Prefecture is heavily influenced by the Kuroshio Current. Even during the winter the water is still warm, and causes frequent
typhoons. Kōchi Prefecture experiences the 2nd most typhoons out of all the Japanese prefectures after
Kagoshima Prefecture.
The 1934 Muroto Typhoon was especially notorious, with the lowest central pressure of any recorded typhoon in Japan at 911.6 hPa when it made landfall on the Muroto Cape. The Ashizuri and Muroto capes are known for their strong winds. As of April 1, 2012, 7% of the total land area of the prefecture was designated as
Natural Parks, namely the
Ashizuri-Uwakai National Park;
Ishizuchi,
Muroto-Anan Kaigan, and
Tsurugisan Quasi-National Parks; and eighteen Prefectural Natural Parks.
