lkai ( ffi i=t ), also written as " ffi till] ," is the name of the people who captured and raised wild boars (pigs) in the Kofun period (4th-6th century). Since it is difficult to distinguishbetween wild boars and domesticated pigs in literature from this period, this paper will refer to both as "boars (pigs)". Boar-shaped haniwa have been the target of archaeological studies on Ikai. Additionally, its horns have been treated in music history as items that have never been introduced into Japan. However, a humanshaped haniwa holding a horn has been excavated along with a boar-shaped haniwa from the Hirugami Kurumazuka kofun in Osaka Prefecture. In this paper, I compared the following archaeological materials: (I) a human-shaped haniwa depicting an Ikai hunting, (2) a haniwa of a person holding a horn, (3) an ornamental image of hunting in a decorated kofun, and (4) images of hunting and horns in a Goguryeo kofun wall painting. I explained their similarities and differences, and analyzed the traits of Ikai and the nature and genealogy of the horns. The method for capturing boars (pigs) in Goguryeo involved horse-riding and using a bow and arrows, but in Kofun-period Japan, only a bow and arrows and hunting dogs were used, and I indicate this as a difference. On the other hand, after examining the horns, I emphasized that most of the horns in Goguryeo were large horns, and they were used as both military musical instruments and as a tool for hunting signals. The results of this analysis indicate that the horn haniwa at the Hirugami Kurumazuka kofun was an "ikai hunting horn." It is thought that the horns in Japan come from the Korean Peninsula, but Ikai was significantly different from Umakai (horse breeding) or Takakai (capturing and raising hawks) in the following ways: time and factors causing immigration, genealogy, and the manner of establishment of culture.
