Daiamondoshi-Pang (lit. "Diamond-sparkle ward") is a city ward in Dengshō 1 - Dosyaeng, the inner city of Kojo's capital Pyingshum. It was carefully planned and built in the late 1840s, after the democratic revolution and the proclamation of the constitution. While the Presidential Palace and the Chancellery as well as Pyingshum City Hall are technically not included in its borders, it forms the heart of the government quarter with the Dyenféi Kō (Arc of Unity) standing in its middle and 10 large avenues symmetrically radiating from it. It it the seat of the nation's parliament, the Jōbunhakke, and many ministries, embassies and international institutions as well as lots of high-grade businesses and retail space. It borders Ōnagara-Pang in the north, Gankakuchō-Pang in the north-east, Goengyuē-Pang in the south-east and Kami so Kuruchi-Pang in the south
After the proclamation of the first constitution in 1834, development for a "new" Pyingshum began, following the aesthetic of the time. Besides placing many government offices in the newly devised government quarter, the new democratic elite also forced the remaining nobility from across the country to move to the new capital, to dissolve their strong regional power structures. As a result, many stately homes can still be seen in the Pang today.
On an area of 2.9 km² there live 10,725 people, giving it a population density of about 3,698 inhabitants/km². Of these 10,725 permanent residents it is estimated that about half of these are actually the wealthy tenants' employees, who live in the rear building. This relatively low living population however doesn't compare to the large amount of people commuting to the Pang every day for work. Daiamondoshi-Pang is the most expensive area in Pyingshum, with prices for 90 year leases in sought-after locations casually reaching 230,000 zubi (~10,000 USD) per square meter.
Daiamondoshi-Pang was the heart of the carefully planned new city centre that was devised and built after the democratic revolution in 1834. The new founders wanted to create an area which was representative as well as being able to house many people of the working class and took inspiration from the style of the Haussmann apartments. Today all buildings in Daiamondoshi-Pang are protected as conservation-worthy and host either one of the many national and international political institutions that are situated there or are home to a very wealthy upper class that is willing to pay large sums of money to live in these exquisite buildings in a very central location. All plots, with the exception of embassies, belong to the state and are only leased for a maximum of 90 year.
Nowadays, preserving the unique architecture is of high importance to the touristic value and integrity of the Pang. Therefore, two general policies were put in place; the front facades facing the streets have to be preserved, and may not be altered. In cases were this is impossible, e.g. in cases of fire, it is not the owners decision how to redevelop the property, but instead a preservation committee from the city comes together and decides whether to rebuild the plot according to still available historic plans, or whether to design a "new" facade that stays in line with the Pang's general architecture. Modern elements are usually not found in the Pang, with the exception of embassies and very few other, exceptional buildings.
On the other hand, everything not directly facing the street may be expanded on or modernised in the frame of the "common" building regulations, which prevent overly eye-catching installations, for example the usual height restrictions still apply. But more importantly, every major change to a building must be approved by all other owners of property in the same plot. Since there are usually dozens of different parties involved, only very few alterations are being made in the courtyards, and if they are, it is common that all affected property owners are given large compensations by the expanding party, to agree with the proposals.
Daiamondoshi-Pang is an internationally well re-known location for high-end expenditure shopping; along Sátarditué-daitō there are countless many boutiques, jewellery shops and other luxury retail facilities catering to the most wealthy customers only. Although window-shopping there is an accepted leisure activity amongst Pyingshum's middle class, at least humorously, the largest portion of customers consists of the city's wealth elite or tourists.
