Matsuyama (松山市, Matsuyama-shi^?) is the capital city of Ehime Prefecture on the Shikoku island of Japan. It is located on the northeastern portion of the Dōgo Plain. Its name means "pine mountain." The city was founded on December 15, 1889.

The city is known for hot springs (onsen) and is home to Dōgo Onsen, the oldest hot spring bath house in Japan. A second favorite tourist spot is Matsuyama Castle. Eight of the eighty-eight temples in the Shikoku Pilgrimage are in Matsuyama.

Matsuyama was in medieval times part of the Iyo-Matsuyama Domain, a fiefdom of Iyo Province consisting mainly of a castle town, supporting Matsuyama Castle. There was a nearby village at Dōgo Onsen to the east and a port somewhat farther to the west at Mitsuhama providing a link to the Japanese mainland (Honshū) and Kyūshū.

Dōgo Onsen was already famous in the Nara period, and Shotoku Taishi visited the spa in the year 596. It is also mentioned in passing in The Tale of Genji. The site of the former Yuzuki Castle is nearby.

Rudy Hartono Kurniawan (Chinese: 梁海量; pinyin: Liang Hailiang), born August 18, 1949) is a former Chinese Indonesian badminton player who won the men's singles title at the World Championship in 1980, and the prestigious All-England Championship trophy eight times, seven times consecutively (1968–1974), in the 1960s and 1970s. He is one of the most famous players in the history of the sport. His sister is also a former world-level badminton player, Utami Dewi Kinard.

During his prime years Hartono won men's singles in most of the international tournaments that he entered. He also played on six consecutive Indonesian Thomas Cup (men's international) teams between 1967 and 1982, the first of these when he was only seventeen, helping Indonesia to win four consecutive world team championships (1970, 1973, 1976, 1979) in what was then a triennial event. His game was characterized by great power, accuracy, agility, mobility, aggressiveness, and coolness under pressure. In 1997 he was among the first group of players inducted into the World Badminton Hall of Fame.
