As culture flourished, so did decentralization. Whereas the first phase of shoen development in the early Heian period had seen the opening of new lands and the granting of the use of lands to aristocrats and religious institutions, the second phase saw the growth of patrimonial "house governments," as in the old clan system. (In fact, the form of the old clan system had remained largely intact within the great old centralized government.) New institutions were now needed in the face of social, economic, and political changes. The Taiho Code lapsed, its institutions relegated to ceremonial functions. Family administrations now became public institutions. As the most powerful family, the Fujiwara governed Japan and determined the general affairs of state, such as succession to the throne. Family and state affairs were thoroughly intermixed, a pattern followed among other families, monasteries, and even the imperial family. Land management became the primary occupation of the aristocracy, not so much because direct control by the imperial family or central government had declined but more from strong family solidarity and a lack of a sense of Japan as a single nation.
What became the aristocracy's primary occupation?
Land management

The permanent snow cover necessary for glacier formation is affected by factors such as the degree of slope on the land, amount of snowfall and the winds. Glaciers can be found in all latitudes except from 20 to 27 north and south of the equator where the presence of the descending limb of the Hadley circulation lowers precipitation so much that with high insolation snow lines reach above 6,500 m (21,330 ft). Between 19N and 19S, however, precipitation is higher and the mountains above 5,000 m (16,400 ft) usually have permanent snow.
Between which north latitudes are glaciers not found?
20 to 27 north

The largest parks in the central area of London are three of the eight Royal Parks, namely Hyde Park and its neighbour Kensington Gardens in the west, and Regent's Park to the north. Hyde Park in particular is popular for sports and sometimes hosts open-air concerts. Regent's Park contains London Zoo, the world's oldest scientific zoo, and is near the tourist attraction of Madame Tussauds Wax Museum. Primrose Hill in the northern part of Regent's Park at 256 feet (78 m) is a popular spot to view the city skyline.
How many royal parks are located in the center of London?
