When Pearl Harbor was attacked and war declared, Murai stepped up to become the chairman of the territory's Emergency Services Committee (ESC).
In 1942, Murai and his wife Hazel volunteered to escort 132 Japanese nationals from Hawaii across a potentially hostile US mainland to North Carolina to be repatriated to Japan.
[4] Murai's leadership status in these organizations led to a lifelong friendship with the future, thrice elected Governor of the State of Hawaii John A.
