Kazuhiro Koshi

1.1. Childhood and Education

Koshi was born on December 23, 1964, in Otaki Village, Nagano Prefecture, Japan. Growing up surrounded by nature, he was active in sports from a young age, participating in swimming and short-distance track and field in elementary school. He was also a skilled skier. Koshi continued his athletic pursuits more seriously in junior high school, and during his time at Nagano Prefectural Kiso High School, he excelled as a shot put athlete. He later attended Sendai University, graduating from its Faculty of Physical Education.

1.2. Athletic Background

At Sendai University, Koshi initially joined the bobsleigh club. However, the rigorous training led him to temporarily quit the club. He rejoined in the autumn of his fourth year. Despite being selected for the All Japan team, his first attempt at a sliding sport fell short when he failed to qualify for the 1992 Winter Olympics in Albertville, France. This setback prompted him to explore other avenues within winter sports.

1.3. Transition to Skeleton

Following his bobsleigh experience, Koshi transitioned to skeleton, a sport that was virtually unknown in Japan at the time. With no domestic coaches available, he faced significant financial challenges. Despite these difficulties, he gradually developed his skills by seeking advice from athletes and coaches from other countries during international expeditions. His dedication and perseverance allowed him to become a trailblazer for skeleton in Japan.

2.1. World Cup and World Championship Performance

Koshi made history as the first Japanese athlete to achieve a podium finish in a sliding sport World Cup event, securing third place at the Königssee World Cup in Germany in 1999. In the following season, he achieved his first World Cup victory at the Nagano event. These accomplishments were unprecedented for a Japanese athlete in bobsleigh, luge, or skeleton. His advanced curve-sliding technique became so renowned that it was dubbed the "Koshi line."

He achieved his best overall seasonal Skeleton World Cup finish twice, placing second in both the 1997-98 and 2000-01 seasons. He also secured a third-place overall finish in the 2002-03 season. In the FIBT World Championships, Koshi's best performance was a fourth-place finish in the men's skeleton event at Nagano in 2003.

Initially, Koshi used foreign-made sleds, but as he ascended to the world's top ranks, he found it increasingly difficult to purchase them. Consequently, from early 2000, he began using sleds manufactured by Nigitec, a metal processing factory in Wakayama Prefecture, Japan.

2.2. Domestic Achievements

Koshi demonstrated significant dominance in domestic competitions. He won the All Japan Skeleton Championships four consecutive times, from 1998 to 2001. He continued to secure victories in the championship, including titles in 2004-05, 2006-07, and 2007-08, further cementing his status as a leading figure in Japanese skeleton.

2.3. Detailed Competitive Record

3.1. 2002 Salt Lake City Olympics

Skeleton was reinstated as an official Olympic sport at the 2002 Winter Olympics in Salt Lake City, Utah, for the first time in 54 years since the 1948 Winter Olympics in St. Moritz. Koshi, at 37 years old, was selected to represent Japan, making his Olympic debut as the oldest member of the Japanese delegation. The media dubbed him "the hope of the middle-aged" or "the hope of the middle class," and he was considered a strong medal contender. However, heavy snowfall on the course the day before the competition created unfavorable conditions for Koshi's style, which relied on technical sliding to overcome slower start dashes. He ultimately finished in eighth place. Despite not winning a medal, this was a significant achievement, marking the first time in 30 years that a Japanese athlete had placed in the top eight in a sliding sport at the Olympics, since the Sapporo Olympics luge doubles event.

3.2. 2006 Turin Olympics

Koshi again represented Japan at the 2006 Winter Olympics in Turin, Italy, once more as the oldest member of the national team. In his first run, he achieved a time that put him within medal contention. However, a mistake in his second run resulted in an 11th-place finish. This outcome deeply disappointed Koshi, who reportedly shed tears over his performance. Despite the setback, he decided to continue his career, feeling that he still had unfinished business in the sport.

3.3. 2010 Vancouver Olympics

Koshi qualified for his third Olympic appearance at the 2010 Winter Olympics in Vancouver, British Columbia, Canada. On September 20, 2009, prior to the Olympics, he participated in the All Japan Push Championships, where he achieved a personal best at 44 years old, finishing 9th. Following this, he announced his intention to retire from top-level competition after the Vancouver Olympics. At 45 years old, he became the oldest Japanese athlete to compete in a Winter Olympics. He finished in 20th place after completing all four runs. Following the competition, Koshi stated that he felt he had reached his "limit value," indicating his intention to retire from competitive racing. However, he also told reporters that he would continue to engage in skeleton "for my health" and suggested he might still compete in Japanese National Championships.

4.1. Coaching and Sports Promotion

From the 2010-11 season, Koshi took on the role of head coach for the Japanese World Cup team. In this capacity, he guided and mentored the next generation of Japanese skeleton athletes. Furthermore, on June 21, 2007, under the sponsorship of Systex, his main sponsor, Koshi co-founded Japan's first skeleton club team, the Systex Skeleton Club, alongside fellow athletes Shinpei Tayama and Hiroatsu Takahashi. He also received sponsorship from Freeport, Hitachi Port Hospital, Club Kong, and Shinshu Sudo. Furthermore, he maintained a trainer contract with Masato Matsumoto. He also actively worked towards establishing a formal governing body for skeleton in Japan, aiming to create a more structured environment for the sport's development.

5.1. Competitive Mindset and Rituals

Koshi was known for his competitive mindset, characterized by setting ambitious goals and publicly declaring them to prevent himself from retreating. He consistently aimed for an Olympic gold medal. Even after announcing his intention to retire from top-level competition following the 2010 Vancouver Olympics, he maintained a resolute stance, stating, "My goal is nothing but a gold medal." Before each race, Koshi performed a pre-race ritual known as "finger vacuum," a distinctive gesture intended to bring him good luck and focus.

5.2. Notable Anecdotes

During the test runs for the bobsleigh competition at the 1998 Winter Olympics in Nagano, skeleton was not yet an Olympic sport. As Koshi performed his runs, many spectators, unfamiliar with skeleton, mistakenly believed that bobsleigh athletes had fallen and were sliding down the track, highlighting the sport's obscurity in Japan at the time.
