Okinawa

Okinawa is the largest island in the Ryku island chain. Naha, the biggest city and capital of the island chain was almost completly destroyed in the land, air, and sea battles that took place on and around Okinawa. Shuri Castle was also destroyed in the battle and was also the base of operations for the Japanese commanders on the island. The overall battle lasted about 82 days and was the bloodies battle in the Pacific War. All of the casualties on both sides put together were more than the number of people killed in the atomic bombings of Hiroshima and Nagasaki put together. This high number of casualties was probably the reason we didn't invade Japan.
