Okinawa Sunabe Seawall Kadena 3" Challenge Coin

Inspired by the Sunabe Seawall on Okinawa, Japan. 

This amazingly designed coin incorporates many themes from the island: the Orion beer lantern, the island's tetrapods, and, of course, the island itself. 

It was designed by a military brat who grew up on the island and returned as an adult to serve on Kadena.
