The manhole covers of Japan are extraordinary. This cover featuring 64 abstracted fish moving in opposite directions as they gobble each other is technically the first decorative cover. Designed in 1977, Naha, a city in Okinawa prefecture of over 300,000 went its own way by eschewing traditional covers. City officials worked with a local illustrator and an old foundry to give people an understanding of where their taxes were going. Sewerage systems are underground and these sunk costs, if you will, have limited visual value. Not here, as the cover served as inspiration for the rest of Japan to adopt designing unique covers. This cover is near the Dragon Pond below the castle. 乾杯!
