Seeking Info on Mr. Yukio Jamaki from Naha Okinawa

[1960MarineFamily]

Recently found a letter from Mr. Yuki Jamaki sent to my father in 1960. They met while my dad was stationed as a Marine in the area. At the time Mr. Yukio Jamaki's address was A C. - 74 Matsuo-Ku, Naha, Okinawa, Ryukyn. Curious to see if he might still be living or perhaps members of his family might still be in the area. It is a long shot, but thought it might be nice to let him know my Dad kept the letter or at least share the letter with his family if Mr. Jamaki has passed away. Any information, including a Google map with the address pinpointed on it or possible family leads would be greatly appreciated.

I'm not sure but the location could refer to block #1 7-4 ie here. In any case, this is the general area.
