直線文をもつ線刻鉄鏃は，弥生時代後期に北部九州において出現した透孔鉄鏃に起源をもち，古墳時代中期の宮崎県域（南九州）において集中的にみられる。１本の線刻は，透孔の退化形態と捉えた。直線文をもつ線刻鉄鏃は圭頭式にほぼ限定でき，広域に流通しない。この線刻鉄鏃は，地下式横穴墓といった特定墓制との関連の中で発達した地域的習俗の一つとみなし，地域内で生産され，地域内で消費されたものと評価した。
いっぽう，円文をもつ線刻鉄鏃は，古墳時代中期の事例が多いものの，すでに古墳時代前期初頭に出現している。弥生時代後期の小孔をもつ鉄鏃との関連も考慮されるが，儀仗性が高い鉄鏃に施される傾向が認められることから，円文は特殊性を際立たせる細工と捉えた。円文をもつ線刻鉄鏃は，圭頭式をはじめ，定角式，柳葉式，二段逆刺鉄鏃など，多様性が認められた。分布の中核が見出せず，朝鮮半島を含め広域に分布している。円文は，倭王権中枢と関連が強い鉄鏃に施されているいっぽうで，地域性が顕著な鉄鏃にもみられる。円文を施す技術や意味が，倭王権にとどまらず，多地域に拡散している可能性がうかがえた。
マロ塚古墳例の確認によって，直線文をもつ線刻鉄鏃の分布が宮崎県内にとどまらず，熊本県域まで広がることが明らかになった。直線文をもつ線刻鉄鏃を用いることに，地域的な紐帯が読み取れる。熊本県域の有力首長層の副葬品に，宮崎県域との関連を示す儀礼用具が含まれることに，被葬者の性格の一端が示されていると評価した。, Iron arrowheads (yajiri) with line engravings (line-engraved iron arrowheads) are found in the Marozuka Tomb. The purpose of this study is to investigate the places of manufacture of the line-engraved iron arrowheads and their significance as grave goods. I collected Kofun Period line-engraved iron arrowheads, organized them into form-based categories, and examined their distribution, and transitions in that distribution.
The line engravings on the iron arrowheads can be broadly divided into two types: a line engraving consisting of only a single straight line, and circular patterns arranged in or around the central area. Both types of line-engraved iron arrowheads are related by being highly ceremonial, but arrowheads thought to be of the parent pattern are different, and there are differences in the periods of their manufacture and in their distribution.
Line-engraved iron arrowheads with the straight line pattern originate from the pierced iron arrowheads found in northern Kyushu from the late Yayoi period, and in the mid-Kofun Period are concentrated in the area of Miyazaki Prefecture (southern Kyushu). The single straight engraved line is conjectured to be (interpreted as) a regressed form of the earlier piercing. Iron arrowheads with the straight line engraving are mostly limited to the specifi c keito- ( jade gui-tablet) style shaped arrowheads, and the range of distribution is also limited. The line-engraved iron arrowheads are treated as a local custom related to the specific grave style of underground yokoana (horizontal) graves, and are considered to have been produced locally and used locally.
On the other hand, even though examples of line-engraved iron arrowheads with circular patterns are common from the mid-Kofun Period, they had already appeared by the beginning of the early Kofun Period. There is a possibility that they are related to the late Yayoi Period iron arrowheads with small holes, but since the circular patterns tend to be applied to iron arrowheads that are highly ceremonial, the circular pattern is conjectured to be (interpreted as) as workmanship undertaken to emphasize that distinctiveness. Among preserved line-engraved iron arrowheads are circular patterns with a variety of shapes, including the keito - type, jo-yokaku (chisel-pointed) type, yanagiba (willow leafshaped) type, nidan-kaeri (double barbed) type, and others. No central point of distribution can be discerned, and they are widely distributed, including on the Korean peninsula. The circular pattern suggests that the iron arrowheads are closely related to the central royal government of Wa, but with strong manifestations, too, of local characteristics. I point out that the techniques and significance of applying the circular pattern were not limited to the royal Wa government, but may have been distributed throughout many localities.
Through the existence of the Marozuka Tomb line-engraved iron arrowheads, it was learned that the distribution of line-engraved iron arrowheads with the straight line pattern was not limited to Miyazaki Prefecture but also extended to the Kumamoto area. It is possible to detect local ties through the use of line-engraved iron arrowheads with the straight line pattern. This means that the burial goods of powerful headmen in the Kumamoto area included ceremonial items that demonstrated a relationship with the Miyazaki area. It is worth noting that this reveals one aspect of the personality of the person buried in the Marozuka Tomb.},
