To date, SMAP had appeared 23 times on Kouhaku since their CD debut in 1991 and were the final performers for the 2003, 2005, 2010, 2011 and 2012 editions. There were only two years when the group did not appear i.e. 2001 when Inagaki Goro was absent due to a suspension of his work due to his traffic offence and 2004 when the members were busy with solo activities and did not spend much time on their music career. Leader Nakai Masahiro was also the Kouhaku host for 6 years in 1997, 1998, 2006, 2007, 2008 and 2009. He was the youngest Shirogumi host to date back then in 1997.
