Q: Question: Who else was part of the Duchy of Brabant with Woluwe? Passage 1:He came from the same area of Japan as future stable-mates Sakahoko and Terao. He was fond of kendo at school. He joined Izutsu stable in 1977, and first reached a sekitori rank in July 1982 when he was promoted to the juryo division. He first made the top makuuchi division in January 1983 but posted a losing record of 4–11 and so was immediately demoted. He won promotion back to the top division in January 1984, and remained there for virtually all of the rest of his career. In September 1984 he defeated a yokozuna for the first time when he upset Kitanoumi in one of the latter's final tournaments. He made the sanyaku ranks for the first time in November 1987 when he reached komusubi, but he proved to be out of his depth and scored only two wins against thirteen losses. He made komusubi once more in September 1990 at the age of 30, but again struggled, winning only three bouts. He suffered from stage fright, losing weight during tournaments because of stomach upsets. This affected his performance against top ranked wrestlers – he stumbled out of the dohyo in a match against Hokutoumi in September 1990 with his opponent barely having to touch him. He was restricted by a foot problem as well as digestive illness towards the end of his career. After 46 consecutive tournaments in the top division he was demoted to juryo after scoring only 4-11 at maegashira 15 in the July 1991 tourney, and he pulled out of the following tournament with a knee injury after fighting only one match. This brought to an end his streak of 1036 consecutive matches from sumo entry. He announced his retirement shortly afterwards.
 Passage 2:Sassari is located in north-western Sardinia, at above sea level. The area rises up on a wide karstic plateau that slopes gently down towards the Gulf of Asinara and the Nurra plain. The city is surrounded by a green belt of thousands of hectares of olive plantations, which from the 19th century have partly replaced the mixed woodlands of oak and other Mediterranean trees as well as the maquis shrubland. The thinly populated Nurra Plain, located to the west, occupies the main part of the region of Sassari, while the urban agglomeration, with a population of about 275,000 inhabitants, is located to the south east. The abundance of water, with about 400 springs and artesian wells, has made for much development of horticulture over the centuries.
 Passage 3:Several archaeological finds on the territory of Woluwe-Saint-Lambert show traces of human activity during the Bronze Age. The first historical mention of the village, however, dates from the 11th century, when some of the forested land near the Woluwe River was cleared for farming. A church was built and dedicated to Saint Lambert, the 7th-century bishop of Maastricht who was martyred in Liège. At the end of the 12th century, the rights to the parish of Saint Lambert were given to the canons of the chapter of St. Michael and Gudula in Brussels. Various charitable organizations and hospitals then started acquiring land in this area. Throughout the Middle Ages, Woluwe was part of the Duchy of Brabant, governed under the usual feudal arrangement of those times. Among the Dukes' vassals were some powerful local lords and landowners. Some of Woluwe's territory also belonged to the powerful Forest Abbey (Vorst in Dutch) and Park Abbey.
