Shōnan gold was first cultivated in 1988, by hybrid crossing the Citrus flaviculpus ({{nihongo|Ōgonkan|黄金柑|"Golden Orange"}}) with Citrus unshiu cv. {{Nihongo|Imamura unshiu|今村温州}} (a variety of Satsuma orange).{{Harvnb|真子|鈴木|浅田|2000|pp=370–1}} It is thought to be a nucellar seedling of the mother plant Ōgonkan.

The cultivation was first conducted at the {{Nihongo|Kanagawa Agricultural Research Institute, Nebukawa Experiment Station|神奈川県農業総合研究所根府川試験場}} in the city of Odawara, although the station has since been bureaucratically reorganized as the {{Nihongo|Nebukawas Sub-Office, under the Ashigara-ku Office, Kanagawa Agricultural Technology Center|神奈川県農業技術センター足柄地区事務所根府川分室}}.{{citation|date=2011-11-10|author=神奈川県農業技術センター(Kanagawa Agricultural Technology Center)|title=かながわ農林水産100の知識 (Kanagawa Nōrinsuisan 100 no chishiki)|url=http://www.agri-kanagawa.jp/nosoken/kentei/|access-date=21 February 2013|archive-url=https://web.archive.org/web/20140415065104/http://www.agri-kanagawa.jp/nosoken/kentei/|archive-date=2014-04-15|url-status=dead}} [http://www.agri-kanagawa.jp/nosoken/kentei/p015_p098.pdf 農業(15～97頁)] {{webarchive|url=https://web.archive.org/web/20121018134901/http://www.agri-kanagawa.jp/nosoken/kentei/p015_p098.pdf |date=2012-10-18 }}, p.70 Further seed selection and propagation was continued until the 12th year (1999) to establish stability of characteristics. The hybrid was registered with the name "Shōnan Gold" (registration number 11469) at Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) in 2003, and the first harvest took place that same year.{{cite web|author=神奈川県農業技術センター (Kanagawa Agricultural Technology Center)|url=http://www.agri-kanagawa.jp/nosoken/tokkyohinshu/shonan-gold.htm|title=湘南ゴールド (Shōnan Gold)|date=December 2007|access-date=2008-04-11}}{{Dead link|date=May 2019 |bot=InternetArchiveBot |fix-attempted=yes }} Shipment started in 2006 (FY2005) with about 2.0 metric tons officially entering the market, or about 450 kg according to a newspaper coverage.{{cite news|author=楠田裕司(Yuji Kusuda)|publisher=Asahi Shimbun|url=http://www.asahi.com/food/news/TKY200804110192.html|title=【神奈川】新種ミカン食後にいかが (Kanagawa-ken: mikan shokugo ni ikaga)|date=2008-04-11|access-date=2008-04-17|archive-url=https://web.archive.org/web/20080415004404/http://www.asahi.com/food/news/TKY200804110192.html|archive-date=2008-04-15|url-status=dead}}

The sphere-shaped fruit averages about 77 g (2.72 oz) each in weight and the rind or peel is yellow. The flesh or pulp is tender, succulent, and sweet, with sugar concentration typically 11–12{{nbsp}}°Bx (i.e. 11–12% by mass). It is fragrant like the Ōgonkan, but is smoother-skinned and easier to peel by hand. The fruit ripens during April and retains excellent flavor until May, which exactly targets the months when the unshū (satsuma) oranges run scarce in the Japanese market.

The young sapling is thorny and grows upright, but as it ages, it loses its thorns and begins to spread its limbs laterally. To encourage earlier fruiting, it is important to train the branches on the young tree so they fan out. Fruiting is bountiful, but has alternate year bearing (biennial bearing) tendencies.

The growers (the {{Nihongo|JA-kanagawaseisho|かながわ西湘農業協同組合}}, i.e., the Japan Agricultural Cooperatives of the "West Shōnan" region of Kanagawa) and the agency (Kanagawa Agricultural Technology Center) jointly held a symposium on the proper method of fruit thinning and planted a test tree, to continue to develop improved cultivation techniques and quality.{{cite web|url=http://kanasan-no-hatake.jp/information/2012/07/action-11.html|work=かなさんの畑 (Kana-san's Field)|title=湘南ゴールドのシンニング（摘果）作業を勉強してきました！ (Went to study fruit-thinning tasks for Shonan Gold!)|author=かながわブランド振興協議会 (Kanagawa brand promotion council|date=2012-07-20|access-date=2012-09-05|archive-url=https://web.archive.org/web/20150621221258/http://kanasan-no-hatake.jp/information/2012/07/action-11.html|archive-date=2015-06-21|url-status=dead}}

The history of planted acreage, annual yields, and shipments, according to the agriculture ministry data are tabulated below.{{cite web|author=農林水産省(MAFF)|title=特産果樹生産出荷実績調査 ("special produce orchard tree production and shipment realization study")|url=http://www.e-stat.go.jp/SG1/estat/List.do?lid=000001102429|access-date=21 February 2013}}{{cite web|url=http://www.kudamononavi.com/graph/category/ca=14/ku=43#nenji|title=果物統計 果物別グラフ 湘南ゴールド (kudamono tōkei..

In statistics up to 2010, Kanagawa prefecture accounted for 100% of Shonan Gold production in Japan.As of Feb-2013, the latest available online at www.e-stat.go.jp site is FY2010 data The major producers are the city of Odawara and the town of Yugawara.

The year is fiscal year, so the first shipment, given as FY2005 in the above data, really occurred in 2006. According to an Asahi Shimbun online edition, the first shipment amounted only to {{cvt|450|kg}}.The wide margin in numbers cannot be accounted for by fresh fruit vs. total, since the government statistics also has a breakdown column for fruits shipped as processed goods.
