[19] In November, the band made their major debut under Toshiba EMI, with the single "Nijūgoko-me no Senshokutai",[16] followed by "EDP (Tonde Hi ni Iru Natsu no Kimi)" in January, both of which rose to the top 50.

[21] By the end of 2006, the band's popularity had increased significantly: their album Radwimps 4: Okazu no Gohan, led by the top-20 singles "Futarigoto" and "Yūshinron" and the top-5 "Setsuna Rensa", debuted at number five[19] and had an initial shipment of more than 100,000 copies.

On 11 March 2012, Radwimps released the single "Hakujitsu" (白日, "Broad Daylight") on YouTube, commemorating the one-year anniversary of the 2011 Tōhoku earthquake and tsunami.
