The Umibōzu are gargantuan Yōkai (creatures of Japanese folklore) that roam the seas and shipwreck fishermen. Some say they are drowned priests, due to their shaven heads and how they typically appear to be praying. They are usually reported as having grey, cloud-like torsos and serpentine limbs. The Umibōzu are typically depicted with only their giant heads exposed above the water, peering down at helpless boats.
Yōkai are the creepy monsters of Japanese folklore. There are many (ranging from faceless women to monstrous skeletons), and they take on various forms. One of those forms is now in a t-shirt! Wear it proudly and show everyone how awesome Yōkai are.
