Question: Who is the author of the book made famous by the heir apparent to the Chrysanthemum Throne?
Context: Sukhrangpha was the king of Ahom kingdom from 1332 CE to 1364 CE.  He had to face the revolt led by his youngest brother Chao Pulai or Tai Sulai (there are confusion in Ahom historians whether Chao Pulai and Tai Sulai were same or different personality.  Eventually he came in terms with Chao Pulai (or Tai Sulai) by appointing him as Charing Raja, a newly created official post to administer the region of Charing.  Later the post of Charing Raja was usually conferred to the heir apparent to the throne.  It can be compared with the title of Prince of Wales of England, where the heir apparent to the throne was conferred with this title. The Dauphine of France (] ) was the wife of the Dauphin of France (the heir apparent to the French throne).  The position was analogous to the Princess of Wales (the wife of the heir apparent to the British throne). Duke of Rothesay (Scottish Gaelic: "Diùc Baile Bhòid" , Scots: "Duik o Rothesay" ) is a dynastic title of the heir apparent to the British throne, currently Prince Charles.  It was a title of the heir apparent to the throne of the Kingdom of Scotland before 1707, of the Kingdom of Great Britain from 1707 to 1801, and now of the United Kingdom of Great Britain and Northern Ireland.  It is the title mandated for use by the heir apparent when in Scotland, in preference to the titles "Duke of Cornwall" (which also belongs to the eldest living son of the monarch, when and only when he is also heir apparent, by right) and "Prince of Wales" (traditionally granted to the heir apparent), which are used in the rest of the United Kingdom and overseas.  The Duke of Rothesay also holds other Scottish titles, including those of Earl of Carrick, Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland.  The title is named after Rothesay on the Isle of Bute, Argyll and Bute, but is not associated with any legal entity or landed property, unlike the Duchy of Cornwall. Charles, Prince of Wales (Charles Philip Arthur George; born 14 November 1948) is the eldest child and heir apparent of Queen Elizabeth II.  Known alternatively in Cornwall as Duke of Cornwall and in Scotland as Duke of Rothesay, he is the longest-serving heir apparent in British history, having held the position since 1952.  He is also the oldest person to be next in line to the throne since Sophia of Hanover (the heir presumptive to Queen Anne), who died in 1714 at the age of 83. Naruhito, Crown Prince of Japan (皇太子徳仁親王 , Kōtaishi Naruhito Shinnō , born 23 February 1960) is the elder son of Emperor Akihito and Empress Michiko, which makes him the heir apparent to the Chrysanthemum Throne. Qian Hongzun (錢弘僔) (925－June 7, 940), formally Heir Apparent Xiaoxian (孝獻世子, "the filial and wise heir apparent"), was an heir apparent to the throne of the Chinese Five Dynasties and Ten Kingdoms Period state Wuyue during most of the reign of his father Qian Yuanguan (né Qian Chuanguan, King Wenmu), but did not inherit the throne on account of his predeceasing his father. 100 Famous Japanese Mountains (日本百名山 , Nihon Hyaku-meizan ) is a book composed in 1964 by mountaineer and author Kyūya Fukada.  The list became famous when Crown Prince Naruhito took note of it .  The list has been the topic of NHK documentaries, and other hiking books. The Crown Prince of Thailand (or Siam; Thai: สยามมกุฎราชกุมาร ; rtgs: Sayammakutratchakuman ) is a title held by the heir apparent to the Thai throne.  First created by King Chulalongkorn (Rama V) in 1886, for his son Prince Maha Vajirunhis, the king's eldest son by a royal wife Queen Savang Vadhana.  Prior to this, the Siamese throne did not have a law or formal system regulating the royal succession.  In 1688 King Petracha of Ayutthaya created the title of Front Palace, which by the Rattanakosin period had become the main title granted to the heir presumptive to the throne.  However few Front Palaces have succeeded to the throne this way, with the exception of King Buddha Loetla Nabhalai (Rama II) in 1809.  After the Front Palace crisis in 1875, the title of Front Palace was abolished and replaced with the title of Crown Prince, who became heir apparent to the throne. Louis of France (1263 or 1264 – Château de Vincennes, before May 1276), was an heir apparent to the French throne.  He was the eldest son of King Philip III of France and his first wife, Isabella of Aragon (1247-1271).  He was the heir apparent to the French throne from August 25, 1270 (at the death of his grandfather Louis IX of France), until his own premature death, at the age of 12-13. Masako, Crown Princess of Japan (皇太子徳仁親王妃雅子 , Kōtaishi Naruhito Shinnōhi Masako ) , born Masako Owada (小和田雅子 , "Owada Masako" ) on 9 December 1963, is the wife of Naruhito, Crown Prince of Japan, who is the eldest son of Emperor Akihito and Empress Michiko and the heir apparent to the Chrysanthemum Throne.  She is a member of the Imperial House of Japan through marriage.  Should the Crown Prince ascend the throne as expected upon his father's abdication, Masako will become empress consort.
