Onsan

Onsan [有算; おんさん] is a city located in Shinkō Prefecture in north Kanton. It has a population of around 168,000, making it the fourth-largest city in the prefecture. Onsan is particularly well-known for its religious history, with over 150 ancient shrines located in or around the city, and five temples situated within the city centre.
During the early Nittori period (1000-1300 AD), local warlord Takabari Yōbi established Keigan Castle in Onsan and took control of the region. He founded the Yōbi clan, who inhabited and governed modern-day Onsan for over 120 years, until the mid-11th century when it came under control of the Hatsu clan, vassals and descendants of the Yōbi who inherited the land after the last chief died heirless. However, their rule came to an end when the region was captured by the Shin clan in 1145.
By the 1600s Onsan became known for its shrines and temples, many of which had been built in the 14th century by local monks and zealots. The largest temple, and the most famous even to this day, is Obokami Temple in the city's western ward. 
== Economy ==
Onsan is a fairly popular tourist destination, with its religious sites attracting both foreign and Kantonese visitors. In 2017, Obokami Temple and Uema Temple were ranked #13 and #25 respectively on a list of 'Best Temples to Visit in Kanton'. Onsan's economy benefits from tourism, but it is also an industrial city, with car-manufacturing factories and processing plants located throughout the city's northern ward. Every year, Onsan holds a festival celebrating fuchigan, a traditional Kantonese street food said to originate in the city; this can draw up to 25,000 attendees each year.
The Onsan Research Park, established in 1997, is a major centre for the Kantonese telecommunications industry, and is where many mobile communications-related companies have set up their research and development centers along with testing facilities.
== Geography ==
Onsan is located near to the cities of Futsukana and Meikai, in the central region of Shinkō Prefecture. The city has one of the highest population densities in the prefecture, with over 200,000 residents squeezed into a space which has been mostly impossible to expand. Onsan has the highest concentration of skyscrapers in Shinkō, and it's estimated that roughly 16% of the population live in flats or apartments. In 2012, the Onsan City Government met with Arihara council to discuss merging plans; however, these plans did not ever come to fruition.
