Okinawa Memorial Day (Okinawa Prefecture)

Okinawa Memorial Day is a public holiday observed in Japan's Okinawa Prefecture annually on June 23 to remember the lives lost during the Battle of Okinawa. It is not celebrated nationally throughout Japan. The Battle of Okinawa was the only ground engagement of the Pacific War fought on Japanese soil. Over 240,000 people died and numerous buildings on the island were destroyed along with countless historical documents, artifacts and cultural treasures. It is estimated that about the half of the war victims were local Okinawan residents, among them children.
