At the heart of their music lies “Kindred Harmony” — a unique musical connection born from their shared roots, expressed through powerful acoustic guitar performances, intricate arrangements, and the natural harmonies that only brothers can create. Together, they have developed a distinctive sound that transcends genres and borders. Their international musical journey began in 2009, when they moved to the UK and immersed themselves in London’s vibrant music scene through busking and open mic performances. After returning to Japan, they expanded their activities across Europe, where they went on to win a band competition in France. Over the years, GoodMoon’s members have performed across Japan, Europe, North America, and Asia, sharing the bill with legendary guitarists Steve Vai and Joe Satriani. Their achievements include winning the Japanese edition of EMERGENZA and performing at major Japanese music festivals such as ROCK IN JAPAN and RISING SUN ROCK FESTIVAL. Following a period of musical activity in Toronto, Canada, the brothers began performing under the name GoodMoon in 2020. As songwriters, composers, and arrangers, the brothers create all of their music themselves. Their work also extends beyond live performances, with music featured in projects for major brands and franchises including TOYOTA, Takamine Guitars, and Cyborg 009. In March 2026, GoodMoon held a headline show at BLUE NOTE PLACE in Ebisu, Tokyo, showcasing their signature blend of dynamic acoustic guitar work, expressive melodies, and seamless brotherly harmonies.
