In Okinawa last year, I had lunch at an A&W root beer and hamburger shop. The placemat on my tray gave a brief history of the company, which has its origins in California and is named for founder Roy Allen and early co-owner Frank Wright.
Okinawa got its first A&W in 1963, and in the 1970s the company ran a radio ad campaign with a little gag that could only work in Japanese.
According to the placemat, the ads connected A&W with the phrase あなたとわたしのドライブイン (Anata to Watashi no doraibuin). As any beginning student of Japanese knows, “anata to watashi” means “you and me,” so あなたとわたしのドライブイン was “our drive-in.”
