Template:Eien no Tsubasa Song

A soft ballad written for the 2007 film For Those We Love, "Eien no Tsubasa" was composed for a work that told the stories of the Kamikaze pilots of World War II and the families they left behind. Tak completed the opening and ending first, and only then did he move onto composing the melody. Throughout production, he rewrote the melody several times until he was content with the result. The lyrics of the song speak of the preciousness of what has assumed importance in one's life. Koshi stated that the lyrics were written about "doing something from the bottom of one's heart, for someone else. When someone does that, they grow wings on their back, and their hearts are rewarded from it. I wrote about that sort of symbolic hope." Tak recalled during an interview with NEWS ZERO: "When I went to Chiran that day, the sky was really blue—really calm. After seeing that, I really opened up to that image." That image was one that made quite an impression, causing Tak to revisit it on two future occasions. The first came in 2010, when he said he thought back to the band's visit to Chiran when he wrote a semi-sequel to "Eien no Tsubasa" titled "hotalu" for his joint album with jazz legend Larry Carlton, TAKE YOUR PICK. Later, Tak would craft an instrumental version from the original composition for his 2012 solo album Strings Of My Soul. The song has not been performed live since B'z LIVE-GYM 2008 "ACTION".
