A frontal platform structure of the tunnel burial chamber was widely constructed during the final Kofun period in Gunma prefecture. The traditional view accounts that this platform structure was autochthonously developed at the end of the Kofun period in the Gunma region. However, recent archaeological surveys reveal that it is distributed over a wide geographic area throughout Japan. Moreover, its origin may go back to the beginning of the Kofun period in the Kōkuri state of the Korean peninsula.The royal graves equipped with the frontal platforms have been built in the Kōkuri state, and their construction continued up to the end of the eighth century in the state of Bokkai. When the tunnel burial chambers were first introduced to northern Kyushu in Japan, some burials were made in this Kōkuri style. This specific burial structure has not been found in the other Korean states, such as the Kudara, the Shiragi nor the Kaya. Therefore, it is safe to say that these early tunnel burial chambers in Japan developed under the influence of the Kōkuri state.Although the tunnel burial chambers with frontal platforms gradually spread into other regions of Japan, they had never come into the Yamato region. This is because the powerful clans in the Yamato region had an alliance with the Kudara state, which was against the Kōkuri state. This political climate inhibited the adoption of the Kōkuri style burials in the Yamato region. In the Kyushu region, on the other hand, the fan-shaped frontal platforms were introduced without resistance. And the tunnel burial chambers with variably modified entrance corridors began to diffuse over the other areas of Japan from Kyushu.The adoption of burial structures from the Korean state has occurred at multiple times through a different route, In the Mino and the Kouzuke regions, the platform structure was first introduced in the sixth century from a route other than the Kyushu, and flourished thereafter. In the Kouzuke region, more than 3,000 burial mounds with frontal platforms were constructed in the seventh century, when the haniwa rituals had already been abandoned. These frontal platforms were possibly made for the internment ritual. As the Yamato state extended its political boundary, the mound builders in the Kouzuke region moved into northern Japan, where they constructed the burials with a similar structure.
