question: The 37th President of the US and which Japanese prime minister created the Okinawa at-large district?
answer: Eisaku Satō
context: Title: Swedish governmental line of succession
  Passage: The Swedish constitution of 1974 allows the Prime Minister of Sweden to appoint one of the Ministers in the cabinet as Deputy Prime Minister ("biträdande statsminister", also unofficially known as "vice statsminister", "Vice Prime Minister"), in case the Prime Minister for some reason is prevented from performing his or her duties.  However, if a Deputy Prime Minister has not been appointed, the Minister in the cabinet who has served the longest time (and if there are several with equal experience the one who is oldest) takes over as head of government.  Note that the person acting as Prime Minister does not do so on a permanent basis: if a Prime Minister dies, resigns or loses a vote of confidence in the Riksdag, the Speaker of the Riksdag will then confer with the parties of the Riksdag and propose a new Prime Minister, who must be tolerated by a majority of the Riksdag.  If the Prime Minister has resigned or lost a vote of confidence, he or she will remain the head of a government "ad interim" until the new Prime Minister assumes his or her office.  The only case where the governmental line of succession becomes relevant is when the Prime Minister dies (upon which the person next in the line of succession serves as the head of a government "ad interim") or when the Prime Minister is on leave or for any other reason incapable of serving, but still remains in office.  This might be compared to the Presidential line of succession in the United States, where the person next in line assumes the Presidency throughout the remainder of the term if the President dies, resigns or is impeached.
  Title: Tottori at-large district
  Passage: The Tottori at-large district (Japanese: 鳥取県選挙区 , Hepburn: Tottori-ken Senkyoku ) is a constituency that represents Tottori Prefecture in the House of Councillors in the Diet of Japan.  Councillors are elected to the house by single non-transferable vote (SNTV) for six-year terms.  Since the establishment of the current House of Councillors electoral system in 1947, the district has elected two Councillors, one each at elections held every three years.  With its 474,963 registered voters (as of September 2015) it is the smallest electoral district for the house.  Accordingly, a 2015 revision of the "Public Officers Election Law" will see the district merged with the Shimane At-large district to create the Tottori-Shimane At-large district; this change will begin to take effect at the 2016 election, at which one Councillor will be elected.
  Title: Kazuhiko Aoki
  Passage: Kazuhiko Aoki (青木 一彦 , Aoki Kazuhiko , born 25 March 1961) is a Japanese politician.  After an earlier career working for a television broadcasting company, he entered the field of politics, serving as secretary to his politician father Mikio Aoki since 1999.  In 2010 he succeeded his father as a member in the House of Councillors for the Shimane at-large district.  A member of the Liberal Democratic Party, Aoki was re-elected to the House in July 2016 as the member for the merged Tottori-Shimane at-large district.
  Title: Okinawa at-large district
  Passage: The Okinawa at-large district is a constituency of the House of Councillors in the Diet of Japan (national legislature).  It consists of the entire prefecture of Okinawa and was created in 1970 following the agreement between US president Richard Nixon and prime minister Eisaku Satō on restoration of Japanese sovereignty over the Ryūkyū islands.  Okinawa is represented by two Councillors electing one every three years.
  Title: Richard Nixon
  Passage: Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th President of the United States from 1969 until 1974, when he resigned from office, the only U.S. president to do so.  He had previously served as the 36th Vice President of the United States from 1953 to 1961, and prior to that as a U.S. Representative and also Senator from California.
  Title: List of Prime Ministers of Japan
  Passage: This is a list of Prime Ministers of Japan, including those of the Empire of Japan, from when the first Japanese prime minister (in the modern sense), Itō Hirobumi, took office in 1885, until the present day.  The office is currently held by Shinzō Abe.  Those Prime Ministers under the Meiji Constitution had a mandate from the Emperor.  The "electoral mandates" shown are for the lower house of the Imperial Diet that was not constitutionally guaranteed to have any influence on the appointment of the Prime Minister.
  Title: Kōchi at-large district
  Passage: The Kochi at-large district (Japanese: 高知県選挙区 , Hepburn: Kōchi-ken Senkyoku ) is a constituency that represents Kōchi Prefecture in the House of Councillors in the Diet of Japan.  Councillors are elected to the house by single non-transferable vote (SNTV) for six-year terms.  Since the establishment of the current House of Councillors electoral system in 1947, the district has elected two Councillors, one each at elections held every three years.  With its 618,834 registered voters (as of September 2015) it is the third-smallest electoral district for the house.  To address the imbalance in representation between districts, a 2015 revision of the "Public Officers Election Law" will see the district merged with the Tokushima At-large district to create the Tokushima-Kochi At-large district; this change will begin to take effect at the 2016 election, at which one Councillor will be elected.
  Title: John F. Kennedy presidential campaign, 1960
  Passage: The 1960 presidential campaign of John F. Kennedy, a United States Senator from Massachusetts, began on January 2, 1960, when Kennedy formally announced his candidacy for 35th President of the United States, replacing incumbent President of the United States Dwight D. Eisenhower.  Kennedy was nominated by the Democratic Party at the Democratic National Convention of 1960, taking place between July 11 and July 15, 1960.  On July 15, 1960, Kennedy named Senator Lyndon B. Johnson of Texas as his official running mate.  Kennedy and Johnson won the election on November 8, 1960, defeating incumbent Vice President and Republican nominee Richard Nixon, who would later go on to be the 37th President of the United States.  Kennedy and Johnson were sworn in as 35th President and 37th Vice President of the United States on January 20, 1961 respectively.  Kennedy would serve as President of the United States until his death in November 1963.
