Kaui M. Kitashima was born and raised in Pearl City on the Island of Oahu.  He is the 6^th of Dan and Merv Kitashima's 7 children. 

He graduated from the Kamehameha Schools in 1998.  While at Kamehameha, Kaui joined the orchestra and played the cello in the 7^th grade.  This was the same year that Kaui took his first and only year of piano lessons.  This started a musical journey that changed his life.  As a junior, Kaui joined the Kamehameha Concert Glee Club and shortly there after was asked to become a musician for the Glee Club where he learned to play the upright bass.  A year later, he was asked to join the newly formed Kamehameha Hawaiian Ensemble as the upright bass player.  In those last two short years of high school, Kaui learned how to play the upright bass, ukulele, and also a little bit of guitar. 

After graduation Kaui decided to continue his education at Brigham Young University-Hawaii campus (BYUH).  While at BYUH, Kaui worked at the Polynesian Cultural Center (PCC) in the Hawaiian village where he continued to refine his ukulele and guitar playing.  In June of 1999, Kaui was asked to become a musician at PCC.  He was excited to learn from a great group of talented and experienced musicians. 

In January of 2000, he left school and his job to serve a mission for the Church of Jesus Christ of Latter-day Saints in Sendai, Japan.  Upon his return in March of 2002, Kaui quickly rejoined the musicians at PCC and continued to learn and grow as a musician and also as an emcee.  Before graduating from BYUH he met and eventually married his Tahitian Princess, Abby H. Matuanui. 

In June of 2005 Kaui left PCC to start his career as the sales manager at Watanabe Floral.  Several months later, he joined Poly Pride Productions and their show at the Waikiki Shopping Plaza where he not only further developed his musicianship but also learned the ins and outs of managing a production.  It was here that he met up with Tyrone Heen, an old friend who became a new music partner.  During their time in Waikiki, Kaui and Tyrone learned to play together and to compliment each other's music. 

Kaui enjoyed his time in Waikiki, but gave it up in June of 2008 to be at home with his wife and daughter, Moehau.  In April of 2009 Kaui joined Po`ohala and he most recently joined the musicians at Paradise Cove.
