The Musashi's are a musical group in Japan, consisting of five cats owned by musician/songwriter Hideo Saitō.
Toward the end of 2007, Saitō posted a video of the cats on YouTube to celebrate Christmas.
In the video, the cats sing to the tune of "Jingle Bells" along with instrumental backup.
On March 3, they released their first single covering a popular Japanese song "Hotaru no Hikari".
A second single titled "Ichinensei ni Nattara" was released on April 7, 2008.
