KAIKI first started playing the ukulele when he was 3 years old. 
 He learned how to play on his own, and his first appearance on stage was at a Hawaii Event when he was 8 years old. 
 At age 17, he went to a four-year medical school in Cebu, Philippines and graduated in a year and a half. When he returned to Japan, he chose to become singer instead of a doctor and he made his debut in June 2016. 
 
 The Uke has always been part of his life, and has always been his guidance. And that is what leads to his "Life Style Music". 
 
 
 
 
 ３歳で初めてウクレレを手にしたKAIKI。 完全独学で、弾きたい曲を耳コピし続け8歳でウクレレプレイヤーとしてハワイ州観光局主催のイベントに出演。 中学卒業後、高校卒業認定資格を取得。 
 １７歳でフィリピンセブへ渡り4年制大学の凖医学部をわずか1年半で卒業。 帰国後、医師になる道は選ばず、大好きなウクレレと歌で2016年6月デビュー。

 暇さえあればウクレレを触っているKAIKI まさに「”Life Style Music”」の体現者である。
