{{Main|Fanclub (album)|Feedback File}}
Due in part to their growing recognition, Asian Kung-Fu Generation would dedicate a significant amount of time the next couple of years going on extensive national tours. Between March 14 and June 26 of 2005, AKG went on an extensive sold-out Re:Re Tour, performing at forty-eight concerts in thirty-eight cities throughout Japan. At the same time, the band released their second DVD, ''[[Eizō Sakuhinshū Vol. 2|Eizō Sakuhinshū Vol. 2: Live at Budokan +]]''. The two-disc video was the band's very first live DVD, as the first disc contains live footage of the entirety of the final show of their "Tour Suihai 2004 - No!Member, November-," at Budokan, where they performed before an audience of over 10,000 people on December 5, 2004. Meanwhile, the second disc contains clips from their first concert at the Shimokitazawa Shelter Club on November 2, 2004. It also includes behind-the-scenes documentary directed by Toshiaki Toyoda and filmed at [[Kanto Gakuin University]], as well as outtakes from the music video for "Kimi to Iu Hana." Upon its release, the video managed to top the Oricon DVD charts for an entire month. On July 9, AKFG held their fifth Nano-Mugen Festival at [[Yokohama Arena]], where they performed with seven other Japanese and UK bands.<ref name="History | NANO-MUGEN FES. 2008"/> To advertise the event, they released a preceding [[Nano-Mugen Compilation|compilation album]] that retained one song from each band attending the festival. Over the next summer, AKG attended a host of festivals, including Summer Sonic 05, Rising Sun Rock Fes. 2005, and Rock in Japan Fes. 05.<ref>{{cite news |url=http://news.bbc.co.uk/2/low/entertainment/4604683.stm |title=Festivals 2005: Your Reviews |access-date=2006-04-17 |author=Evans, Jason |date=2005-08-31 |work=[[BBC News]] |publisher=MMIX}}</ref><ref>{{cite web | title=特別企画 SUMMER SONIC 05大特集！ | url=http://www.mtvjapan.com/event/summersonic05/list.html | work=[[MTV Japan]] | publisher=[[MTV Networks]] | access-date=2009-05-13 | archive-url=https://web.archive.org/web/20171217105950/http://www.mtvjapan.com/event/summersonic05/list.html | archive-date=2017-12-17 | url-status=dead }} {{in lang|ja}}<!--Japanese--></ref><ref>{{cite web | title=冬のサマソニ、SONICMANIA 05を先行独占放送！ | url=http://www.mtvjapan.com/event/sonicmania/ | work=MTV Japan | publisher=MTV Networks | year=2006 | access-date=2009-05-13 | archive-url=https://web.archive.org/web/20160303233110/http://www.mtvjapan.com/event/sonicmania/ | archive-date=2016-03-03 | url-status=dead }} {{in lang|ja}}<!--Japanese--></ref> They also appeared as guests on ''GOGOICHI –SPACE SHOWER CHART SHOW–'' on November 27 on SPACE SHOWER TV. The band closed the year by releasing the single, {{nihongo|"[[Blue Train (Asian Kung-Fu Generation song)|Blue Train]]"|ブルートレイン|}}, followed up by a brief tour entitled, "Tour SUI CUP 2005 - Winter Dragon" in December.

The band began 2006 with the release of their upcoming album's second single, "[[World Apart]]." The single was unique in that it featured a song in which Kensuke Kita stood as lead singer. It was AKFG's first song to achieve number-one single status, also it was the year that the band was finally able to acquire their very own studio. They then took part in live performances in LIVE SUPERNOVA DX on February 16, 2006.<ref>{{cite web |url=https://www.j-wave.co.jp/topics/0601_supernova9.htm |title=McDonald's TOKYO REAL-EYES presents LIVE SUPERNOVA DX |author=Migaku, Huzita |access-date=2008-11-07 |work=[[J-Wave]] |publisher=J-WAVE |date=January 2006 |archive-date=2016-03-03 |archive-url=https://web.archive.org/web/20160303231432/https://www.j-wave.co.jp/topics/0601_supernova9.htm |url-status=dead }} {{in lang|ja}}<!--Japanese--></ref> On March 15, AKG released their third full-length album, {{nihongo|''[[Fanclub (album)|Fanclub]]''|ファンクラブ|}}.

To commemorate their ten-year anniversary, Asian Kung–Fu Generation released their first compilation album, ''[[Feedback File]]'' on October 25. Rather than featuring hit singles, the nostalgic album was primarily compiled of [[B-sides]], live performances, and old demos from their early indie days. Even though it retained little new material, the compilation was met by commercial success and managed to debut at number two on the Oricon charts. AKFG then went on a two-month arena tour entitled, Tour Sui Cup 2006-2007: The Start of a New Season. Well over 100,000 fans attended this tour, which traveled through eight cities and featured guest performances by bands from Japan and the United States.<ref name="ASIAN KUNG-FU GENERATION: Biography"/> In the midst of the tour, AKFG was commissioned by the director of the then-upcoming anime film, ''[[Tekkon Kinkreet]]'', to compose a theme song for the movie. The band created a song called, {{nihongo|"''[[Aru Machi no Gunjō]]''"|或る街の群青}} and released it as a year-end single prior to the film's debut.<ref>{{cite web |url=http://www.sonymusic.co.jp/Music/Arch/KS/ASIANKUNG-FU/KSCL-1068/index.html |title=ASIAN KUNG-FU GENERATION: "''Aru Machi no Gunjō''" (或る街の群青) |access-date=2008-10-11 |work=ASIAN KUNG-FU GENERATION Official Website |publisher=Ki/oon Records Inc |year=2006| archive-url= https://web.archive.org/web/20080919151149/http://www.sonymusic.co.jp/Music/Arch/KS/ASIANKUNG-FU/KSCL-1068/index.html| archive-date= 19 September 2008 | url-status= live}} {{in lang|ja}}<!--Japanese--></ref> As a sign of their increasing cultural prominence, the band came to be parodied in a volume of the popular ''[[Hellsing]]'' [[manga]] by members of the [[Holy See|Vatican]] named, "The Vactikung."
