Suzuki competed in race walking from a young age and his international debut came at the 2004 World Junior Championships in Athletics. He was the 10,000 metres walk bronze medallist at the 2005 World Youth Championships in Athletics and the 2006 World Junior Championships in Athletics. He began competing in the senior ranks a year later and came sixth in the 20 km walk at the Asian Race Walking Championships and fourth at the 2007 Summer Universiade. In the following two years he came tenth and fifth at the Asian Race Walking Championships. A personal best time of 1:22:05 hours in 2009 earned him a place at the 2009 World Championships in Athletics but he was among the last walkers to finish in the 20 km race.
