SMAP was a Japanese boy band, composed of Masahiro Nakai, Takuya Kimura, Goro Inagaki, Tsuyoshi Kusanagi, and Shingo Katori. The group was created in 1988 by music producer Johnny Kitagawa, founder of Johnny & Associates, originally as a six-piece with Katsuyuki Mori, until his departure from the band in 1996. After making their debut in 1991, the group took the Japanese entertainment industry by storm, becoming the most successful boy band in Japanese history and the bestselling band in Asia, often referred to as a "national treasure" and a "fortune and property of the country" in Japan. SMAP was regarded as an iconic figure in Japan, after achieving an unprecedented level of success in numerous genres in the entertainment industry, including music, television, film, radio, and theater, as a group and individually.

SMAP was heavily involved in philanthropic activities. They have actively offered philanthropic support especially to the victims and regions affected by the 2011 Tohoku earthquake and tsunami and the 2016 Kumamoto earthquakes. On August 26 and 27, 1995, SMAP hosted NTV's annual telethon, 24 Hour Television, and raised 1.1 billion yen. On August 27 and 28, 2005, Kusanagi and Katori hosted the 24 Hour Television, again, and raised one billion yen.  In 2011, after the Tohoku earthquake and tsunami, they bought a 30-second television commercial block in their weekly television program, SMAPxSMAP, to air a commercial on the information about the Japanese Red Cross Society and a message from the band members encouraging people to donate. Rather than reusing the ones aired in the past, they have been reshooting the commercial every time they have a taping and have them aired every week at the end of the program. Since March 2011, they have actively worked as the members of Marching J, a charity organization established by their agency, Johnny & Associates. Each band member have also made individual donations.  On May 4, 2011, their first and only digital single, "Not Alone" was released. Initially scheduled to serve as the band's 46th single, it was later canceled and released digitally in light of the earthquake and the situation in Japan, considering circumstances in power shortages and distribution. One hundred yen per single downloaded was donated to the victims. On July 23 and 24, 2011, Nakai hosted the annual twenty-seven hour long television special, FNS 27 Hour Television, for the fifth time. A special episode of "Bistro SMAP", a cooking segment on SMAPxSMAP, was aired during the show, titled "Bistro SMAP On The Go". Four members flew to regions that were affected by the earthquake and tsunami, Kimura and Inagaki to Iwate prefecture and Kusanagi and Katori to Fukushima. The four members cooked a total of one-thousand meals to the victims evacuated in these areas. Nakai started to host his own music show, Ongaku no Hi, meaning "music day", to show their support to all those affected by the earthquake and tsunami. The program is aired every summer since 2011. On August 17, 2011, the band released their fifth compilation album, SMAP Aid, to support the people affect by the earthquake and tsunami. Two-hundred yen per album sold were donated to the victims. Being that it was the band's twentieth anniversary, many predicted a tour after the release of the album but the band canceled it due to power shortage in Japan that year.  After the 2016 Kumamoto earthquakes, the content of their 30-second long commercial changed, adding a new message by the band members toward the victims in Kumamoto. On April 24, ten days after the earthquake, Nakai made an unannounced surprise visit to an elementary school in Kumamoto, used as a shelter for the evacuees. He, later went back to Kumamoto on 2 more occasions: May 7  and again on May 15 with Katori.  On June 12, Kimura made a visit to Kumamoto as well.
