Cavalcade Wargames have released their 28mm Wako Pirate figure.
From their website:
Our Wako Pirates have arrived. Originating from Japan, China and Korea, these bands of scrappy seamen pirated vessels traveling the Pacific, the Sea of Japan, the Yellow Sea, the East China Sea and the South China Sea. The Wako also waged war against fortifications and villages in Japan, China and Korea during the 13th through 16th centuries. The Wako are $13.99 for 6 infantry and $8.99 for 3 command figures.
