Hey, I took three quarters of Japanese in college, shouldn’t you pronounce it “so-ko-day”?
You might think so. When devising the name, we used the Hepburn method of romanization, in which “dei” can represent the sound “dee”. Though we realized people were pronouncing it “day”, we thought “Sokodei” looked cooler onscreen than “Sokodi” and decided to stick with it. You can say “day” if you want. But we say “dee”.
