Oak vs Gifu

Informations

An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers, meaning that the trees are monoecious. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on their species. The acorns and leaves contain tannic acid, which helps to guard from fungi and insects. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus.

Gifu (岐阜市, Gifu-shi) is a city located in the south-central portion of Gifu Prefecture, Japan, and serves as the prefectural capital. The city has played an important role in Japan's history because of its location in the middle of the country. During the Sengoku period, various warlords, including Oda Nobunaga, used the area as a base in an attempt to unify and control Japan. Gifu continued to flourish even after Japan's unification as both an important shukuba along the Edo period Nakasendō and, later, as one of Japan's fashion centers. It has been designated a core city by the national government. Located on the alluvial plain of the Nagara River, Gifu has taken advantage of the surrounding natural resources to create both traditional industries (including Mino washi and agriculture) and tourism opportunities such as cormorant fishing. Mount Kinka, one of the city's major symbols, is home to a nationally designated forest and Gifu Castle, a replica of Nobunaga's former castle.

Gifu also hosts many festivals and events throughout the year. Two major rail lines connect Gifu to Japan's national and international transportation infrastructure. JR Central's Tōkaidō Main Line runs through the city, connecting it with Nagoya, one of Japan's largest cities, and the surrounding area. The city has a direct train route to Chubu Centrair International Airport and facilities capable of hosting international events. Gifu has active relationships with six sister cities. As of 1 June 2019, the city has an estimated population of 401,534 in 178,246 households, and a population density of about 1,972 inhabitants per square kilometre (5,110/sq mi). The total area of the city was 203.60 square kilometers (78.61 sq mi).
