The Mikado Band is a musical group from Japan that plays traditional Japanese music. The band's name comes from the Gilbert and Sullivan operetta, The Mikado. The band consists of three members: OBI (3 letters), which stands for 'Oboe, Bamboo Flute, and Shamisen.' The oboe is a woodwind instrument, the bamboo flute is a type of flute, and the shamisen is a three-stringed instrument. Together, these instruments create a unique sound that is distinctively Japanese.
