What country does sushi & karaoke come from?

The story behind the answer

Japan is correct. Modern sushi—vinegared rice paired with seafood—was refined in Edo (Tokyo) in the 1800s, with nigiri popularized by Hanaya Yohei as fast street food. Karaoke, meaning “empty orchestra” (kara = empty, oke = orchestra), was invented in Japan in the 1970s by Daisuke Inoue and became a staple of social nightlife.

Memory tip: both terms are distinctly Japanese. “Sushi” refers to the vinegared rice (su = vinegar), not just raw fish, and “karaoke” describes singing with an instrumental track. Linking cuisine (sushi) and culture (karaoke) helps remember their shared Japanese origin.
