in June. In continuation of her 10th anniversary celebration, Misia released her very first digital single, "Catch the Rainbow" (produced by Sakoshin) on August 30, 2008.] She wrapped up The Tour of Misia Discothèque Asia in early March, a tour that brought her to Seoul, Singapore, Hong Kong and Shanghai and opened her eyes to the different responses of crowds as she noted "In Japan, it is like people are melting into one group in their excitement, but in Singapore young couples started to kiss. I often see Japanese couples hand-in-hand, but it is rare to see them showing they love each other in front of others." In 2008, Misia drew near more than 200,000 spectators, second only to Ayumi Hamasaki in the number of concert-goers for a solo female artist in Japan. The June 2009 single "Ginga/Itsumademo" was inspired by Misia visiting her grandfather for the last time before his death, for which she stated upon its release, "I thanked him for taking me out for a walk when I was a child, for teaching me how to fold origami and make shadow pictures, and for telling me stories. I couldn't stop saying thank you." This and her later single "Hoshi no Yō ni...", which was used as the theme song for the film Mega Monster Battle: Ultra Galaxy were included on Misia's 9th studio album Just Ballade. Misia's 2010 tour titled "Hoshizora no Live VI" included performances in the open air and within forests in order to raise awareness of biodiversity and to support her anthropological work. For the 2010 FIFA World Cup in South Africa, Misia recorded the song "Maware Maware" and performed it at Nelson Mandela Square in Johannesburg before the Japan vs Cameroon game. She was also inspired by the International Year of Biodiversity and wrote the song "Life in Harmony", eventually chosen by the Convention on Biological Diversity to be the song for the conference. In 2011, Misia returned to recording with the song "Ashita e" to raise money for victims of the 2011 Tōhoku earthquake and tsunami and "Kioku", Misia's first official single in nearly a year and a half. These songs, along with "Maware Maware" and "Life in Harmony" were included on Misia's 10th studio album Soul Quest. She followed up Soul Quest with the cover album Misia no Mori: Forest Covers, which includes a cover of Charlie Chaplin's "Smile" which is
