M. Nakai Repair Service is a family owned and operated business. Masao (Poker) Nakai founded the company in Honolulu in 1945 and repaired gas pumps. In 1961, the business was incorporated and moved to 288 Mokauea St and has been there ever since. In 1972, Masao retired and the business was handed over to his sons, Earl (Masa) and Ronald. The business is now run by Earl and his son, Scott, and grandsons Reyn and Landon.
