Declan Suzuki-McComb is a left-handed batter and right-arm medium-pace bowler who has been part of Japan's international setup since making his T20I debut against Indonesia in 2022. He has developed into a useful all-round option for Japan, contributing with both bat and ball while also gaining experience across the East Asia-Pacific pathway. His most significant bowling performance came against Bhutan in 2026, when he claimed his maiden T20I five-wicket haul, returning 5/20 from four overs.

Suzuki-McComb has also been part of Japan's squad at the 2022 Asian Games and has featured regularly in their subsequent regional campaigns. His ability to contribute in both disciplines has made him a valuable member of the side, while his international experience has continued to grow since his debut. That progress saw him included in Japan's squad for the 2026 Asian Games in Aichi-Nagoya, giving him another opportunity to represent the country on the continental stage.
