Sayonara
The oriental city Sayonara was featured in two episodes of The Super Mario Bros. Super Show!, "Mario Meets Koop-zilla / Fortune Teller" and "Karate Koopa / Adee Don't". In the former, the city was a modern metropolis filled with large buildings, though the latter portrayal displayed an older fuedal town.
One possible explanation for the severe difference in appearance is that in "Mario Meets Koop-zilla / Fortune Teller", most of the town is entirely destroyed. So it's not unreasonable to assume that the simpler design featured in "Karate Koopa / Adee Don't" might be a result of fewer buildings existing, combined with the fact that there wasn't much time to rebuild since their last encounter with King Koopa.
Dr. T. Garden, inventor of Super Sushi, is a resident of the city.
