Rizhao (Chinese: 日照), alternatively romanized as Jihchao, is a prefecture-level city in southeastern Shandong province, China. It is situated on the coastline along the Yellow Sea, and features a major seaport, the Port of Rizhao. It borders Qingdao to the northeast, Weifang to the north, Linyi to the west and southwest, and faces Korea and Japan across the Yellow Sea to the east.

The name of the city literally means "sunshine".^[4] The city is known for its sustainability, and it mandates solar-water heaters in all new buildings. Rizhao city was recognized by the United Nations as one of the most habitable cities in the world in 2009.^[5][6]

The city population stands at 2,968,365 people as of the 2020 Chinese census, of whom 1,172,205 live in the urban area of Donggang District.

Rizhao is located at the place where the ancient Dawenkou culture and the Longshan culture flourished. Rizhao belonged to the Dongyi people during the Xia and Shang dynasties (2070-1046 BC), and to Ju and Yue States in the Spring and Autumn period (770-476 BC) and the Warring States period (476-221 BC). It became a part of Langye Commandery in the Qin dynasty (221-206 BC). Rizhao was named Haiqu County (海曲縣) during the Western Han (206 BC-25 AD) and Xihai County under the Eastern Han (25-220 AD).^{[citation needed]}

During the Tang dynasty, together with Ju County, Rizhao belonged to Mi Prefecture of Henan Prefecture. In the second year of the Yuanyou Period of the Song dynasty, Rizhao Township was established, with the name meaning "(the first to get) sunshine". In the 24th year of the Dading Period of the Jin dynasty, Rizhao County was established. In 1940 it came under the control of the Chinese Communist Party during the Chinese Civil War. After being a county and since 1985 a city under the administration of Linyi, Rizhao became a prefecture-level city within Shandong province in 1989.^{[citation needed]}

The Field Museum of Natural History in Chicago has done field survey archaeological work in Rizhao over the years.^[7]

Rizhao has a temperate, four-season, monsoon-influenced climate that lies in the transition between the humid subtropical (Köppen Cwa) and humid continental (Köppen Dwa) regimes. Winter is cool to cold and windy, but generally dry, with a January average of −0.3 °C (31.5 °F). Summer is generally hot and humid, but sweltering days are rare, with an August average of 25.7 °C (78.3 °F). Due to its proximity to the coast and being on a peninsula, it experiences a one-month delayed spring compared to much of the province. Conversely, fall is milder than inland areas in Shandong. The annual mean temperature is 12.95 °C (55.3 °F). On average, there are 2,530 hours of bright sunshine annually, and the relative humidity is 70–74 %.^{[citation needed]}

• Donggang District (东港区)

The seaport serves as a site for loading and unloading iron ore and coal.

The alliance aims at building a shipping and logistics center in Northeast Asia.^[14] The new iron ore port of Lanqiao is located close to it as is the Lanshan port region.^[15]
