This song was composed for the International KODOMO Choir   Festival held during the World Symposium on Choral Music in   Kyoto 2005. In 2006, the composer arranged this song into   the mixed choir version for the joint concert in Singapore.   A choir in Singapore, a choir from the Philippines, and the   choir of Ko Matsushita himself from Japan were gathered.   Through the work divided into three groups, our prayer for   peace spreads like waves turning into whirlpools. This piece  should be sung powerfully and brilliantly.
