Does anyone know what these caps that frequently appear in japanese media are called? In english they are called Peaked Caps.Marked for deletion (Old)

Rather than classifying by shape, caps in Japan seem to be classified by role/purpose, and don't inherently refer to a specific form. Some examples I've seen are kanbou (官帽; official/bureaucrat cap), seibou (制帽; regulaton/law cap) and gakuseibou (学生帽; student cap - I think this is what Raidou is wearing)
