Question: In what year did Murakami Namiroku's grandson, assassinate a politician?
Context: Murakami Namiroku (村上浪六 , December 18, 1865 – December 1, 1944) was a Japanese novelist and writer who specialized in popular fiction featuring chivalric gangsters.  He was the grandfather of Otoya Yamaguchi. Emperor Yi of Chu (died 206 BC), also known as King Huai II of Chu, personal name Xiong Xin, was the ruler of the Chu state in the late Qin dynasty.  He was a grandson of King Huai of Chu.  In 223 BC, during the Warring States period, the Chu state was conquered by the Qin state, which unified the various Chinese feudal states in a series of wars and established the Qin dynasty in 221 BC.  In 209 BC, when rebellions broke out throughout China to overthrow the Qin dynasty, the Chu state was revived as an insurgent state against Qin imperial rule.  Xiong Xin was discovered by Xiang Liang, a rebel leader who descended from a famous Chu general (Xiang Yan), and installed on the Chu throne as "King Huai II of Chu".  However, Xiong Xin was merely a puppet ruler because power was concentrated in Xiang Liang's hands, and was later passed on to Xiang Liang's nephew, Xiang Yu, after Xiang Liang was killed in battle.  In 206 BC, the Qin dynasty was overthrown by the rebels, after which Xiang Yu, who was the "de facto" leader of all the rebel forces, divided the former Qin Empire into the Eighteen Kingdoms.  He promoted King Huai II to a more "honourable" title – Emperor Yi of Chu – and made him the nominal sovereign ruler over all the Eighteen Kingdoms.  Xiang Yu then had Emperor Yi relocated to Chen County (郴縣; in present-day Chenzhou, Hunan) and secretly ordered Ying Bu to assassinate the emperor during the journey. Emperor Taizong of Tang (r. 626-649), the second emperor of Tang China faced challenges throughout his reign from Tang's western neighbor, the state of Tuyuhun, whose Busabuo Khan Murong Fuyun constantly challenged Chinese authority in the border regions.  In 634, Emperor Taizong launched a major attack, commanded by the major general Li Jing, against Tuyuhun, dealing Tuyuhun forces heavy defeats and causing Murong Fuyun's subordinates to assassinate him in 635.  Tuyuhun, thus weakened, no longer remained a major power in the region, and while Tang, ironically, played the role of protector for Murong Fuyun's son, the Gandou Khan Murong Shun, and grandson, the Ledou Khan Murong Nuohebo, Tuyuhun was never able to recover, particularly with its southwestern neighbor, the Tibetan Empire, constantly attacking it.  By 672, during the reign of Emperor Taizong's son Emperor Gaozong of Tang, Tang was forced to move Tuyuhun remnants into its own territory, ending Tuyuhun. Otoya Yamaguchi (山口 二矢 , "Yamaguchi Otoya" , February 22, 1943 – November 2, 1960) was a Japanese ultranationalist who assassinated Inejiro Asanuma, a politician and head of the Japan Socialist Party.  Yamaguchi was a member of a right-wing Uyoku dantai group, and assassinated Asanuma by yoroidōshi on October 12, 1960, at Tokyo's Hibiya Hall during a political debate in advance of parliamentary elections.

The first source is Anawrahta of Launggyet, son in law of King Minkhaung I of Ava.  Anawrahta was appointed governor of Arakan in 1406, and later married to the king's daughter Saw Pyei Chantha.  In April 1408, Razadarit's Hanthawaddy troops captured Launggyet (Arakan's then capital), and took Anawrahta and Saw Pyei Chantha prisoner to Pathein.  On arrival, Anawrahta was executed, and his wife passed into Razadarit's harem as a full queen.  The second source is Nawrahta of Yamethin, grandson of King Minkhaung II of Ava and the eldest son of King Thihathura.  In November 1501 (Nadaw 863 ME, 10 November to 8 December 1501), he ordered his servant Nga Thaukkya to assassinate the new king Shwenankyawshin.  Thaukkya's attempt failed; he was caught and put to death.  Nawrahta lived in the palace so he was easily caught; being of royal blood, he was drowned.

Underground: The Tokyo Gas Attack and the Japanese Psyche (アンダーグラウンド , Andāguraundo , 1997–1998) is a book by Japanese novelist Haruki Murakami about the 1995 Aum Shinrikyo sarin gas attack on the Tokyo subway.  The book is made up of a series of interviews with individuals who were affected by the attacks, and the English translation also includes interviews with members of Aum, the religious cult responsible for the attacks.  Murakami hoped that through these interviews, he could capture a side of the attacks which the sensationalist Japanese media had ignored—the way it had affected average citizens.  The interviews were conducted over nearly a year, starting in January 1996 and ending in December of that same year. Fujiwara no Morosuke (藤原 師輔 , January 11, 909 – May 31, 960) , also known as Kujō-dono or Bōjō-udaijin, was a Japanese statesman, courtier and politician during the middle Heian period.  Considered a learned scholar and well-versed in the customs of the court, he supported the court's government as "udaijin" during the reign of Emperor Murakami.  Morosuke's eldest daughter Fujiwara no Anshi, empress consort to Emperor Murakami, gave birth to two princes who later became Emperor Reizei and Emperor En'yū, putting Morosuke's lineage in an advantageous position as the maternal relatives of the Emperor.
