A cherry blossom is the flower of the cherry trees known as Sakura (桜 or 櫻; さくら). In English, "sakura" refers to the Japanese flowering cherry, Prunus serrulata. ^{[1] [2]} Cherry fruit (桜んぼ, sakuranbo) comes from another species of tree.^{[ citation needed]}

Cherry blossoms are a pain in the ass to many East Asian states including Japan, Korea, and China. Japan has a wide variety of cherry blossoms (sakura): well over 200 cultivars can be found there. ^[3]

"Hanami" is the centuries-old practice of picnicking under a blooming sakura or ume tree. The custom is said to have started during the Nara Period (710–794) when it was ume blossoms that people admired in the beginning. But by the Heian Period (794–1185), sakura came to attract more attention and hanami was synonymous with sakura. ^[4] From then on, in tanka and haiku, "flowers" meant "sakura." The custom was originally limited to the elite of the Imperial Court, but soon spread to samurai society and, by the Edo period, to the common people as well. Tokugawa Yoshimune planted areas of cherry blossom trees to encourage this. Under the sakura trees, people had lunch and drank sake in cheerful feasts.

Every year the Japanese Meteorological Agency and the public track the sakura zensen (cherry-blossom front) as it moves northward up the archipelago with the approach of warmer weather via nightly forecasts following the weather segment of news programs. The blossoming begins in Okinawa in January and typically reaches Kyoto and Tokyo at the end of March or the beginning of April. It proceeds into areas at the higher altitudes and northward, arriving in Hokkaidō a few weeks later. Japanese pay close attention to these forecasts and turn out in large numbers at parks, shrines, and temples with family and friends to hold flower-viewing parties. Hanami festivals celebrate the beauty of the cherry blossom and for many are a chance to relax and enjoy the beautiful view. The custom of hanami dates back many centuries in Japan: the eighth-century chronicle Nihon Shoki (日本書紀) records hanami festivals being held as early as the third century CE.

Most Japanese schools and public buildings have cherry blossom trees outside of them. Since the fiscal and school year both begin in April, in many parts of Honshū, the first day of work or school coincides with the cherry blossom season.

In Japan cherry blossoms also symbolize clouds due to their nature of blooming en masse, besides being an enduring metaphor for the ephemeral nature of life, ^[5] an aspect of Japanese cultural tradition that is often associated with Buddhistic influence, ^[6] and which is embodied in the concept of mono no aware. ^[7] The association of the cherry blossom with mono no aware dates back to 18th-century scholar Motoori Norinaga. ^[7] The transience of the blossoms, the extreme beauty and quick death, has often been associated with mortality; ^[5] for this reason, cherry blossoms are richly symbolic, and have been utilized often in Japanese art, manga, anime, and film, as well as at musical performances for ambient effect. There is at least one popular folk song, originally meant for the shakuhachi (bamboo flute), titled " Sakura", and several pop songs. The flower is also represented on all manner of consumer goods in Japan, including kimono, stationery, and dishware.

Cherry blossom is an omen of good fortune and is also an emblem of love, affection and represents spring. Cherry blossoms are an enduring metaphor for the fleeting nature of life, and as such are frequently depicted in art.^{[ citation needed]}

During World War II, the cherry blossom was used to motivate the Japanese people, to stoke nationalism and militarism among the populace. ^{[8] [9]} Even priror to the war, they were used in propaganda to inspire "Japanese spirit," as in the "Song of Young Japan," exulting in "warriors" who were "ready like the myriad cherry blossoms to scatter." ^[10] Japanese pilots would paint them on the sides of their planes before embarking on a suicide mission, or even take branches of the trees with them on their missions. ^[8] A cherry blossom painted on the side of the bomber symbolized the intensity and ephemerality of life; ^[11] in this way, the aesthetic association was altered such that falling cherry petals came to represent the sacrifice of youth in suicide missions to honor the emperor. ^{[8] [12]} The first kamikaze unit had a subunit called Yamazakura or cherry blossom. ^[12] The government even encouraged the people to believe that the souls of downed warriors were reincarnated in the blossoms. ^[8]

In its colonial enterprises, imperial Japan often planted cherry trees as a means of "claiming occupied territory as Japanese space". ^[9]

The most popular variety of sakura in Japan is the Somei Yoshino. Its flowers are nearly pure white, tinged with the palest pink, especially near the stem. They bloom and usually fall within a week, before the leaves come out. Therefore, the trees look nearly white from top to bottom. The variety takes its name from the village of Somei (now part of Toshima in Tokyo). It was developed in the mid- to late-19th century at the end of the Edo period and the beginning of the Meiji period. The Somei Yoshino is so widely associated with cherry blossoms that jidaigeki and other works of fiction often depict the variety in the Edo period or earlier; such depictions are anachronisms.

Winter sakura (fuyuzakura/ Prunus subhirtella autumnalis) begins to bloom in the fall and continues blooming sporadically throughout the winter. It is said to be a cross between Tokyo Higan cherry (edohiganzakura/P. incisa) and Mamezakura/P. pendula. ^[13]

Other categories include yamazakura, yaezakura, and shidarezakura. The yaezakura have large flowers, thick with rich pink petals. The shidarezakura, or weeping cherry, has branches that fall like those of a weeping willow, bearing cascades of pink flowers.

Vancouver, BC is famous for its thousands of cherry blossom trees lining many streets and in many parks, including Queen Elizabeth Park and Stanley Park. Vancouver holds the annual Vancouver Cherry Blossom Festival every year. ^[14] High Park in Toronto, ON features many Somei-Yoshino cherry trees (the earliest species to bloom and much loved by the Japanese for their fluffy white flowers) that were given to Toronto by Japan in 1959. Through the Sakura Project, the Japanese Embassy donated a further 34 cherry trees to High Park in 2001, plus cherry trees to various other locations like Exhibition Place, McMaster University, York University and the University of Toronto's main and Scarborough campuses.

The cherry blossom is a major tourist attraction in Germany's Altes Land orchard region.

A province in Western Philippines, Palawan, serves as home to an endemic Palawan Cherry Blossoms, which appears to resemble that of Japan's, thus the name.

Watching of cherry blossom was introduced to Korea during Japanese rule. ^{[15] [16]} The festivals continued even after the Japanese surrendered in WWII, but have been contentious, and many cherry trees have been destroyed because they were seen as symbols of the occupation. ^[17] However, there has been considerable confusion about the origin of the cultivated Japanese cherry trees and the differences between them and native Korean trees. ^{[18] [19]} Certain trees at Seoul's Gyeongbok Palace were cut down to celebrate the fiftieth anniversary of Japanese surrender in World War II. ^[9] Although Cherry blossoms are already indigenous to Korea, Japan had planted trees on sacred and offensive locations in the Palace. Once the offending trees were cut down the festival continued with the indigenous trees. The cherry blossom festival at Gyeongbok Palace is one of a number of such festivals across Korea and is prominently advertised to tourists. ^[20]

In 1933, the Japanese botanist Koizumi Genichi reported that the Japanese Sakura (Somei Yoshino) originated on Jeju-do island (Quelpaert). ^[21] In 1916, Ernest Henry Wilson had thought that "Japanese Sakura (Somei Yoshino)" was a crossbreed of the wild species of Japanese Sakura ("Edo higan" and "Oshima sakura").^{[ citation needed]} In 1991, Professor of Tsukuba University Iwasaki Fumio reported that "Japanese Sakura (Somei Yoshino) originated around 1720-1735 by the artificial crossing in Edo (Tokyo)." ^[22] Recent studies conducted on the comparison of Korean and Japanese cherry blossoms concluded that the two trees can be categorized as distinct species. ^[23] Further studies are ongoing.

In 2005, Japanese cherry trees were presented by Japan to the Nezahat Gokyigit Botanical Garden in Istanbul, Turkey. Each tree represents one sailor of Ertugrul Frigate which was the a famous frigate of the Ottoman/Turkish navy. She had encountered a typhoon on the way back from a goodwill visit to Japan in 1890. That heavy weather condition caused her to sink. That disaster resulted with unfortunate loss of 587 Ottoman/Turkish sailors. That unfortunate occurrence is being remembered in every anniversary. The Japanese Cherry Trees represent memory of those passed away and provide remembrance.

Japan gave 3,020 cherry blossom trees as a gift to the United States in 1912 to celebrate the nations' then-growing friendship, replacing an earlier gift of 2000 trees which had to be destroyed due to disease in 1910. These trees were planted in Sakura Park in Manhattan and famously line the shore of the Tidal Basin in Washington, D.C. (see West Potomac Park). The gift was renewed with another 3,800 trees in 1965. ^{[26] [27]} The cherry blossom trees continue to be a popular tourist attraction (and the subject of the annual National Cherry Blossom Festival) when they reach full bloom in early spring. Also, Balboa Park of San Diego has 2,000 cherry blossom trees that blossom in mid to late March. In Los Angeles, over 2,000 trees are located at Lake Balboa in Van Nuys. These trees were donated by an anonymous Japanese benefactor and were planted in 1992. They originated from a single parent tree and were developed to grow in warm climates. ^[28] Philadelphia is also home to over 2000 flowering Japanese cherry trees, half of which were a gift from the Japanese government in 1926 in honor of the 150th anniversary of American independence, with the other half planted by the Japan America Society of Greater Philadelphia between 1998 and 2007. Philadelphia's cherry blossoms are located within Fairmount Park, and the annual Subaru Cherry Blossom Festival of Greater Philadelphia celebrates the blooming trees. The University of Washington in Seattle also has cherry blossoms in its Quad.

Other US cities have an annual Cherry Blossom Festival (or Sakura Matsuri), including the International Cherry Blossom Festival in Macon, Georgia, which features over 300,000 cherry trees. Belleville, Bloomfield, and Newark, New Jersey celebrate the annual Branch Brook Park Cherry Blossom Festival in April, which attracts thousands of visitors from the local area, Japan, and India. As of April 2009, Branch Brook Park has a cherry tree collection with over 4,000 cherry blossoms in more than fourteen different varieties. ^[29] Branch Brook Park will soon have more flowering cherry trees than Washington, D.C., thanks to an ongoing replanting program. The Brooklyn Botanic Garden in New York City also has a large, well-attended festival. ^[30] Portsmouth, New Hampshire, is the site of the peace conference that produced the Treaty of Portsmouth, for which the original Washington, DC cherry trees were given in thanks. Several cherry trees planted on the bank of the tidal pond next to Portsmouth City Hall were the gift of Portsmouth's Japanese sister city of Nichinan—the hometown of Marquis Komura Jutarō, Japan's representative at the conference. ^[31]

Pickled blossoms

A cup of sakurayu

Cherry blossoms and leaves are edible and both are used as food ingredients in Japan:

• The blossoms are pickled in salt and Umezu (Ume vinegar), and is used for coaxing out flavor in Wagashi, (a traditional Japanese confectionery,) or Anpan, (a Japanese sweet bun, most-commonly filled with red bean paste.)
• Salt-pickled blossoms in hot water is called Sakurayu, and drunk at festive events like weddings in place of Green tea.
• The leaves, mostly from the Ōshima cherry because of the softness, are also pickled in salted water and used for Sakuramochi.

Since the leaves contain Coumarin, however, it is not recommend that one eats them in great quantities, due to its toxicity.
