【‘Ukulele but Pop】 is Tomoki’s theme. Since meeting the `Ukulele in 2013, he has won the Grand Prize at the 8th The `Ukulele Contest (#1 in Japan) in only 2 and a half years. He also has won first place in the International Contest the following year on Oct, 2016. From the gentle sound that touches the heartstrings to his aggressive performance that undermines the image of this small instrument fascinates all those that hear his sound.
