Den Janlaphan was born as the eight of nine children in Phichit, Thailand. He entered Thammasat University at the age of 16, and began boxing, making his amateur debut in 1995. He turned pro, and made his professional debut in January, 2000, in Bangkok, Thailand. He transferred to the Kadoebi Houseki Gym in Tokyo, Japan, and made his Japanese debut in August, 2001 as "Eagle Okuda", winning by first-round knockout.
He won the WBC Minimumweight title in January, 2004, beating Jose Antonio Aguirre by decision. He made his first defense in May of the same year, but lost his second defense in December, 2004 against Isaac Bustos. The fight was stopped in the 4th round due to a shoulder injury by Kyowa. He made his return in August, 2005, against Katsunari Takayama, who had beaten Bustos to win the WBC Minimumweight title. Kyowa won by decision, regaining his title.
On January 9, 2006, he defeated Ken Nakajima (14-2-0) by 7th round tko. On May 6, 2006, he defeated future light flyweight champion Rodel Mayol (22-0) by a 12-round unanimous decision.

He met Akira Yaegashi, the WBC's 6th ranked contender, on June 4, 2007, in Yokohama, Japan, for his fourth defense (fifth total). Kyowa dominated the young challenger from the first round to make his fourth straight defense by unanimous decision. He lost a point for an accidental head-butt in the 2nd round, but knocked down Yaegashi in the 10th round to secure his victory. All three judges awarded him the win by over ten points. This fight also utilized the open scoring approved by the World Boxing Council. Every four rounds, they would announce the official scoring of the fight.
