It was originally during a fiery competition, when the opponent fans attempted to disrupt his concentration, but it became a chant dedicated to Imazumi.
From the late 1980s to the early 1990s, he was a player deserving to be called a "senior boss" who contributed greatly to the popularity of Japanese rugby.
It was hard to be difficult to understand, while he did not know what to do, on the other hand, although he did not play for the Japanese national team, his talent was highly appreciated by Onishi Tetsunosuke.
The following year, he was called up in Japanese National team for the 1995 Rugby World Cup in South Africa, He also played for Japan sevens.
In March 2005, Imazumi left Sundelphis (remaining the head coach in the rugby club) and went to Graduate School of Public Management at Waseda University.
